[Captivate Android Development] sRedwolf:
Has anybody else had trouble getting this kernel to NOT overclock their device? Even though I have the setting in the recovery to not overclock I'm still running at 1200MHZ. Other kernels don't seem to have this issue.

I was running talondev (with apex) previously and it on Apex enables overclocking via an app that creates an init.d script that does the following:

echo 1200000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

When I disable overclocking using that app that file is removed and the phone goes back to 1000mhz

As soon as I install Corn though (on apex) the phone runs at 1200MHZ. I can see that scaling_max_freq is set to 1200000 even though no init.d script that sets that exists.

If I manually create an init.d script that sets scaling_max_freq to 1000000 then the phone runs at 1000mhz like I want so technically I don't really have a "problem" - but I'm just curious as to why it's happening. Trying to figure out whether my device has a problem or the Kernel has a problem.

I noticed somebody was experiencing a similar issue in the Corn Kernel v7.06 thread as well.
[Captivate Android Development] gibson3659:
The max frequency for Corn can be set in the tweaks section of recovery.
[Captivate Android Development] sRedwolf:
Right - there's an option "overclock to 1200MHZ" which I have set to OFF. So I've assumed that means the device should be running at 1000MHZ(after a reboot) but it's not - it's always 1200. The only way to force it to 1000 is to setup my own init.d script. Not seeing that behavior on other kernels - when left to its own devices with talondev for example it runs at 1000.
[Captivate Android Development] jvc73:
I was going through the thread right now because I discovered the same thing!

Might also be what is causing me the randow reboots.
[Captivate Android Development] sRedwolf:
I'm using 1.05c with Apex 12.4 and I also have static problems with Bluetooth. Beyond that though this kernel seems pretty rock solid.
[Captivate Android Development] mirotvorets:
did anybody resolve the problem with bluetooth headset? there is trouble only in this kernel. when i make calling via bluetooth i hear my companion very good but he hear only very loud noise in his phone. i suspect there is trouble in the audience chip via bluetooth.
[Captivate Android Development] :
Yes and it has been discussed several times in thread. It is an issue with i897 modems and i9000 kernels (the only possible combo) that won't be resolved.
[Captivate Android Development] Yuna:
Can you point me to technical explanation of issue?
[Captivate Android Development] id_snake:
see PM ...
[Captivate Android Development] Yuna:
How do i enable logcat?
[Captivate Android Development] Yuna:
Can this kernel be updated for Jw5 (364mb ram)?
[Captivate Android Development] anishz:
Can i use this with JVZ rom [Saurom]?
[Captivate Android Development] Wdustin1:
So what's the word on call quality?

[Captivate Android Development] poncespr:
Does not work. I get no audio on handset or speaker. Sbamboo 2.4.

I am on I9000 bootloaders. Should I flash I897 bootloaders?
[Captivate Android Development] Geezer000:
Me either. No audio on handset or speaker. On Saurom

Sent from my Cappy using the XDA app.
[Captivate Android Development] mtcarey:
Yes, it's compatible with JVS - JW1 ROM's.
[Captivate Android Development] kitkitfok:
I also have this problem, I am on i897 bootloaders............

mtcarey, should I flash i897 base modem?
[Captivate Android Development] mtcarey:
For anyone having this problem... what ROM are you using?
[Captivate Android Development] mtcarey:
Bootloader or modem should not make any difference with audio, but use I9000 modem only!
[Captivate Android Development] kitkitfok:
Mosaic 8.5 JVT, come form Semaphore JVZ 2.1.1cbm ............

Should I flash stock JW1 and test again?
[Captivate Android Development] poncespr:
Sbamboo 2.4 based on 2.3.6 SW1

What rom have you tested it on?

Only reason I am on I897 roms is audience support.

My hearing is not that good anymore.
[Captivate Android Development] Geezer000:
I am on Saurom
[Captivate Android Development] mtcarey:
I've got it running on Apex with no audio problems. Have you checked for any init.d scripts which might be messing with the audio?
[Captivate Android Development] Geezer000:
Removed Init-d completely and still no dice.
[Captivate Android Development] mtcarey:
I'm going to flash Saurom and check this out.
[Captivate Android Development] Geezer000:
I've tried both the ODIN and CWM packages and they both do it.
[Captivate Android Development] grkmaster:
Just realized now that i have no audio either on calls either. I get the sound confirmation from the phone when it connects to dial but no ringing or voice. im Running Mosaic 8
[Captivate Android Development] kitkitfok:
I flash back to Semaphore JVZ 2.1.1cbm, audio alive :)

In CWM, I see some set of tweak (existz, yours etc.....), should I apply some of them?

I feel not as smooth as Semaphore kernel..........
[Captivate Android Development] mtcarey:
Ok... flashed Saurom, flashed Corn, no problems with audio. If I (or someone) can remember where to find your hardware revision, that might be helpful information. Also, make sure that the Voodoo Control app detects Voodoo Sound present.
[Captivate Android Development] ChuckDaEngineer:
Mtcary, I tried this on SauRom and couldn't get audio either. Employing my extreme lack of respect for authority, I violated the rule of only using I9000 modems with I9000 kernals and flashed 3 different I897 modems and they all worked with SauRom and your new kernal. I don't pretend to know why but that is my status. I will keep testing for battery life, etc. Thanks for all the hard work, the CM7 guys wouldn't even consider trying this. Very impressive.
[Captivate Android Development] mtcarey:
I respect your lack of respect. Interesting about the modem... I guess I just bought into the conventional wisdom. Do you have audio now?
[Captivate Android Development] grkmaster:
Question, mtcarey - Would there be a reason why my ringtones changed by applying your kernel? I realized this because my notifications werent working and checked the ringtones and the ones i had were replaced. I changed back to talon and they are back again
[Captivate Android Development] kitkitfok:
Thank you your testing!

I flash back to corn kernel again and flash i897 base modem I897UCKK4, audio worked.
[Captivate Android Development] warri:
Confirmed. Was running a i9000 Modem, no sound, flash i897 modem sound returns.
[Captivate Android Development] kitkitfok:
Will have any conflict with ThunderBolt! v2.2.0 and their add-on?

I want to flash them because I feel laggy with your kernel (I have apply init.rc tweak injection syscorps.tweaks, and install zipalign init.d script in CWM)......

The LMK/OOM may be need to set on the aggressive side.
[Captivate Android Development] mtcarey:
Thunderbolt tweaks should work fine.

Have you tried ondemand or smartass governor? Default is conservative.
[Captivate Android Development] mtcarey:
Weird. I'm going to have to figure that one out.
[Captivate Android Development] sinichi21:
Maybe there should be an option on the voice call setting that should enable disable the noise supression. Like on captivate rom
[Captivate Android Development] :
Alright, so I am about to flash SBamboo JW1, this kernel and then the i897 KK4 modem. Should it give me audio and audience?
[Captivate Android Development] poncespr:
Confirmed working after flashing kk4 modem. Will try it a day or two and see how it goes.

Cheers.
[Captivate Android Development] golfslicer:
I can confirm that you need a captivate modem for this to work. I also found another problem that you fixed on the captivate version. The ringtones on the sd card are not showing up.

Since you have the source for the kernel, can you turn off the rat selection on captivate modems?
[Captivate Android Development] pcguy23:
Great work, makes me want to flash an I9000 rom again

do you still get the hspa+ data speeds using an I897 modem?
[Captivate Android Development] :
Do you mean HSDPA and HSUPA (which is HSPA)? HSPA+ was/is AT&T's fake 4G on the Infuse, Atrix, etc; If so, I am getting about 2.5 downloads with KK4
[Captivate Android Development] DAGr8:
if the kernel allows for it o be turned off I can add that option easily ..
[Captivate Android Development] mtcarey:
I just flashed SBamboo, then Corn kernel. Audio is fine with I9000 modem. I'm mystified why the modem should effect audio for some folks... I'll slog through the code and try to figure it out.
[Captivate Android Development] :
I'm going to try KC1 using SBamboo, and I'll report back.

EDIT: Yeah, on KC1, no audio :/
[Captivate Android Development] sinichi21:
What about the upload speed of it?
[Captivate Android Development] :
Scratch that, on KK2 I am getting about 3 down, and .5 up. :eek:
[Captivate Android Development] poncespr:
My speed went from 3megs download/ 1.2megs upload, to 2megs diwnload and 300kbps upload :-/
[Captivate Android Development] CPeterson:
Has anyone tried an i896 or Armani modem to see if they support both the Audience chip and HSUPA?
[Captivate Android Development] Wdustin1:
i installed the kj3 modem and it gets regular crappy upload speeds but it sounds great so i think it gets chip support
[Captivate Android Development] mindphaser2k9:
Great kernel, but I have '?' symbols instead of Russian letters in file names. How can I fix this? ROM is Saurom JVZ for Captivate. With Semaphor kernel all Russian symbols are ok.
[Captivate Android Development] Geezer000:
For all the people not getting audio with a i9000 modem, do you have a 897 or 896?

I have an 896 and get no sound.

Sent from my Cappy using the XDA app.
[Captivate Android Development] ChuckDaEngineer:
Everything seems to work so far. I will try some other modems and watch battery life. (Fingers crossed).
[Captivate Android Development] mtcarey:
Dang! I fixed that in the KK4 kernel but somehow it slipped into this one. New version 1.02 posted which fixes this (and other sd card problems).
[Captivate Android Development] Wdustin1:
AWWW that sucks back to I897 roms for me. i hope you can figure out the charger bug i would like to give I9000 another shot with some Corn lovin
[Captivate Android Development] 4-2ndtwin:
mtcarey,

So what is ur word on ur kernel as far as modems go. I read ur post earlier where u said only use i9000 modems, but I see it working for a majority of others only with Captivate modems ??

And great work by the way. Appreciate what u do here on XDA.

[Captivate Android Development] DAGr8:
Back in froyo days the first baseband was somehow relevant to the second ..

For enabling different basebands and stuff wouldn't surprise me it has something to do with it

so what modem you start from then witch did you flash on top..

Try different match(full wipe in beteeen of course)
[Captivate Android Development] mtcarey:
I'm using the I9000 modem that comes with SBamboo with no problems. I'm not sure that the folks with modem problems are a "majority"... anyone else using I9000 modem with success?
[Captivate Android Development] 4-2ndtwin:
^ Thanks for the reply. And the "majority" I was refering to was just from the posts up to now. I realize the user themselves and what they do/did affect things as well.

Once again thanks...

i was on SBamboo with the stock modem and everything was ok then i flashed corn kernel and no sound, i then flashed KJ3 modem and i had sound again. i never tried reflashing a I9000 modem though
[Captivate Android Development] mtcarey:
Did you (or can you) see if there is anything related in a logcat dump?
[Captivate Android Development] boog:
Oh, man! This is awesome!

Do you have source somewhere? I think this could be ported back to i897 roms!
[Captivate Android Development] 4-2ndtwin:
That would b awesome...i897 GB Roms with i897 modems that have noise cancellation, up speeds like i9000, & etc., etc.

The Devs here r Awesome !!!

I actually started out making an I89x kernel with all the goodies from the I896 source, but I couldn't get it to boot past the initial splash screen. Tried everything... finally went the other way with the I9000 source. I'll set up a Github account and post both... maybe someone else will be able to get it to boot.
[Captivate Android Development] bobapunk:
I would love to have i9000 speed with a working audience chip. I am on kk4 (illuminance 3.0.1) with a sweet ICS theme. Can this kernel be used with with my combo? I am guessing not, but it can't hurt to ask! From what I read here, it seems like the speed is set by the modem, not the kernel... True?
[Captivate Android Development] mtcarey:
An I897 ROM (KK4) like Illuminance needs an I897 kernel. This kernel is for I9000 ROMs. As for speed, are you talking about download/upload speeds? If so, the modem and kernel combination, as well as the geographic area you are in, are factors.
[Captivate Android Development] kitkitfok:
I use smartassV2. Overclock to 1200Mhz.

KeepTheLightsOn don't work.
[Captivate Android Development] watsa:
Good work mtcarey, finally some progress on the lone thing left in cappy development... I was like :eek: when I first read the title of this thread...

You are the man
[Captivate Android Development] :
You just ended so many debates with this kernel :)

I've been running it all day, and now that the SD Card bug is fixed, it's amazing. Less than a day, and I am already impressed!
[Captivate Android Development] mtcarey:
Thanks! It was very tedious stitching it together... like doing a really nasty jigsaw puzzle.
[Captivate Android Development] nappent:
I'm running SBamboo V2.5 with and i9000 bootloaders and no luck with the sound. And I did a full wide when installing the rom. I'm not sure how a few people have gotten it to work.
[Captivate Android Development] mtcarey:
I'm also running SBamboo... the only difference I can think of is that I have the I897 bootloader. For those with audio problems (and those without) what bootloader do you use?
[Captivate Android Development] nappent:
Any chance you can post Version 1.01 to see if it works with past version... Maybe it is a issue if we don't install the kernels in series

Also, what file system are you running ext4?

---------- Post added at 11:00 PM ---------- Previous post was at 10:47 PM ----------

I switch to the I897 bootloaders and no luck...
[Captivate Android Development] mtcarey:
People had that problem with v1.01. I am on Ext4, but that shouldn't make any difference. So you flashed the I897 bootloader and that didn't work? Hmmm....
[Captivate Android Development] nappent:
Yep on I897 bootloader and no luck still. If I'm not wrong but I believe the Canadian Captivate does not have the hardware for this to work so that might be why this is not working for those people. If you have a US AT&T Captivate this chip is there. I'm going to reflash SBamboo just to make sure it wasn't a bad flash or something.
[Captivate Android Development] mtcarey:
The Audience chip code came from the Canadian (I896) source code, so I'm pretty sure they are the same. Whaddaya say, Canadians?
[Captivate Android Development] Yuna:
Hey, those having problems - do you use i9000 modem or i897 one? If the first - you are fools :)
[Captivate Android Development] boog:
Not sure that we will get the up speeds on the i897 side, will still be limited to the i897 modem, but having working source will be nice.

I never could get the i896 source to boot, but I did make a port of talon that would boot, I just couldn't get past the bluetooth audio problems from running an i9000 kernel on i897. I am hoping/thinking you might have solved that issue getting audience to work.

Kinda hoping to see if I could do the same with this one :)

Your work has been amazing!
[Captivate Android Development] kitkitfok:
After 12 hours use, no different of 3G HSDPA Network speed with i897 KK4 modem.

Mobile Signal and Battery status as same as before (i9000 modem).

Voice call I feel have great improve.

Hope you can tweak the kernel that make it faster and better (please fix KeepTheLightOn issue). :D
[Captivate Android Development] mindphaser2k9:
Actually the kernel is quite fast, just need to choose ondemand governor in CWM. Though maybe not so fast as Semaphor or Talon, but close.
[Captivate Android Development] sa1yan:
OMFG, SCREW ICS. :DDD

What are some good roms for this base?
[Captivate Android Development] golfslicer:
Notes flashed from Saurum to SBamboo just to see if I could match MTcarry 1st post.

After flashing you must delete all files in /system/etc/init.d folder or your rom will run slow. You can delete them after flash too, I did. Flash the rom/ it will boot log in and reboot/apply Corn Kernel, Apply tweaks such as sio and SmartAss V2 and under misc, make sure 1200 is selected and init.d scripts, pretty much everything there as Yes. Reboot and then Recovery again and flash Paul Diddy Theme 2.2.

I could not duplicate the KG3 modem as working, it has data and all, but when trying to use the phone it has only interference and no way to talk on both phones calling from and this captivate.

Data upload speeds on KK4 are pathetic, I haven't found one that works any better than KK4.

I9000 modem are not working for voice for me. I got 125/1806/1228 on semaphore kernel and only 230/2734/239 with KK4 on speedtest apk.

Quadrant Score is 3135

I have also tried the ICS rom 4.03, it is fast, but no statusbar toggles and menu is much more cumbersome and different - not for me.

I have tried the KK4 roms and Sbamboo 2.5 is better IMO.

Now if we could only get the i9000 modems to work with this rom with voice on calls working.

Mtcarrey says it does, but I cannot duplicate it, Using usa captivate, i897 bootloaders on ext4 @ 1200.

Build 1010

[Captivate Android Development] mtcarey:
Thanks for the review! I'm still scratching my head over the modem issue since the I9000 modem works fine on my phone. I do have a very early build Captivate and there might have been hardware changes later which cause the conflict. Not sure I can do anything about it but I'll look through the code again.
[Captivate Android Development] mtcarey:
CM7 uses an entirely different partitioning scheme than Samsung. I know Recovery will not work for sure.
[Captivate Android Development] ChuckDaEngineer:
I was running SauRom with the new 1.01 version and was using the KK4 modem from the native I897 leak and after upgrading to the 1.02 version I decided to go back and try the I9000 KC1 modem and viola...phone sound works!!. Don't know how or what I may have done but I will probably play with this combo over the holidays. Now the real question is ... Which flavor is the right one to use?
[Captivate Android Development] mtcarey:
From what I've been reading in researching this problem, the I9000 modem performs some software-based noise cancellation which might be stepping on the hardware resources used by the Audience chip.
[Captivate Android Development] mtcarey:
What is the KeepTheLightsOn issue? First I've heard of it. As far as making it faster, it's pretty tough to beat the work done by existz on Talon without copying his code. I've tried to use only generic bits in the Corn kernel.
[Captivate Android Development] aryn.galadar:
If it helps (or hurts, I guess ;-) ), I'm on a 1006 build, and I'm having the same no-audio-on-calls issue with the I9000 modems.
[Captivate Android Development] golfslicer:
Anybody know why phone signal degrades when connected to WiFi. My dbm signal goes from -83 dbm with wifi off and immediately degrades to -91 or worse as soon as I enable WiFi.

Right now it jumped to -89 then to like -101.
[Captivate Android Development] sa1yan:
It may be because when you connect to WiFi, it disables your data connection. I noticed that whenever my data connection is active, my signal shoots a couple bars, so disabling it may do the opposite.

Or I may be crazy.
[Captivate Android Development] mtcarey:
You probably don't want to hear this, but my signal stays 89-91 with wifi on or off. :D

After I flash your kernel, it don't work.

I think your are copying his old code, because it is early issue of Talon:

0.1.3

Revert back to old touchkey driver

Fixed Issue with KTLO

Compiled sound/soc/codecs as O2
[Captivate Android Development] mtcarey:
I don't have his old code... I have his new code. And I did not copy anything from Talon - just used it (and others) as a cross reference for compiler switches. :D
[Captivate Android Development] sa1yan:
So does the audience chip work with non i897 modems or not? Cause I'm on KG3 and I see that the drivers folder is still there in Root Explorer.
[Captivate Android Development] mtcarey:
Based on feedback, my "official" position is that you need an I897 modem. I've already changed the OP.
[Captivate Android Development] golfslicer:
Check the about phone, I tried what you said, flashed KC1 and rebooted and it was working too. Did a speedtest and got lousy upload speed. I then reflashed another i9000 modem and no dice, reflashed kc1 and no dice, reflashed captivate modem and working again, then reflashed kc1, still working, but when I checked about phone, it still showed me on KK4. So if you think your working on KC1, Check about phone and see if you actually are because I am not.
[Captivate Android Development] ChuckDaEngineer:
I was definitely on KC1. I got voice but quality was terrible. I believe the I897 modern is going to be the way to go until further notice.
[Captivate Android Development] mikel.canovas:
Awesome kernel, there are some great i9000 roms out there that vastly outperform the newest ICS builds in performance, battery life, and features. Thanks for allowing me to use them

This kernel is supposed to fix that issue, and you need to use a i897 modem.
