If your volume is at max and your sound level coming out of your headphones is low then you're using headphones not designed for portable use (high impedance headphones). You will need to use a dedicated headphone amplifier to get sufficient volume from them with the phone.

I believe he is jacking into his head unit via the external input. Have you tried adjusting the input gain for the line input on the head unit. On my Pioneer unit it has an adjustable dedicated line input which I use with my Evo.

Revision 4.1.9.1-CFS BETA works best with my EVO (Rooted Stock 2.2 DeOdexed) thus far. No issues; everything works great and screen scrolling is super smooth. Battery life is 16-20 hours, depending on usage. Thanks for all of your efforts !!!

Your right I am going in through my head unit. It doesnt have any gains though as it is a stock head unit. I added a soundgate unit to the stock radio in order to play through the stock aux port. I have also hooked up my Zune to it using the same cable and had no volume problems.
[EVO 4G Android Development] Tiffany84:
Hey, can somebody tell me what might be the best for me using no set CPU, the bfs or the cfs? Thanks.
[EVO 4G Android Development] DaWhip:
I did something similar. After a couple reboots from too much OC I lost 3G and 4G. I reflashed all the radios and did a new hands free activation and it fixed it. Probably a different corruption than what you had, but there is definitely the potential to fubar something when overclocking
[EVO 4G Android Development] netarchy:
One of the many reasons I stress to make backups (and incidentally also why you have to explicitly use a tool to actually overclock). You never know when murphy's law is gonna kick in.

has anyone tried using this kernel with fresh Eco 3.2.0 and does it break anything or is everything fine

Sent using XDA App
[EVO 4G Android Development] Winter Rain:
I've been having issues with a couple of apps using 4.191 CFS(and technically they've been happening since 4.12, just haven't posted before now) on several different roms. I've got an 003 with an Epson screen and I don't overclock.

1.)I can't adjust the brightness in Aldiko by swiping up and down the edges of the screen. It's like it just doesn't register.

2.)Draw! does something similar. It will work fine for a while then stop registering touch input except in the menus. It seems like it happens when the kids draw near the edges of the screen but that could be confirmation bias.

Neither bug occurs on stock, in CM6, or on the 2.1 kernels. Not a big deal, but I thought I better report in in case these are symptoms of a larger problem or in case someone has a work around. Thanks for all your work, netarchy.

Edit: Yeah, y'know what? I'm an idiot. Just tried the new Fresh 3.2 and I'm getting the same problems on that. So I guess it's just Sense, Froyo, and my phone. Oh well. Sorry to waste anyone's time.
[EVO 4G Android Development] Compusmurf:
Don't do it. He's using the new kernel. When the new OTA kernel goes out public, Netarchy has already "promised" an update. :)
[EVO 4G Android Development] crypt0kiddie:
So with Flipz new Fresh Rom being out with a new kernel, does that mean that you will be working on that kernel soon or is there no source yet?

im running 4.1.8-cfs-bfq-(OC) with fresh-evo-3.2.0.0 and it runs great..its stable and snappy, no problems what so ever.... .... i dnt really care about the new kernel/battery life i prefer speed and stability ..... (i have a charger at home, car and work)....
[EVO 4G Android Development] cLOUDFAn:
been using 4.1.9 cfs on fresh 3.1

updated to fresh 3.2 yesterday

it seems stock 3.2 kernel gives me much better battery life than 4.1.9 cfs (while 4.1.9 is much snappier)

looking forward a new netarchy mod kernel :D
[EVO 4G Android Development] donatom3:
I have to agree my eyes not bleeding from the less than 30 fps is more important to me than getting an extra 10% or so in standby battery life.
[EVO 4G Android Development] netarchy:
There is no source for that kernel available right now as it's from a leaked OTA that has not been released publicly by sprint/htc. Once it's officially released they will be obligated to release any source code changes, and then I'll have something to work with.

[EVO 4G Android Development] netarchy:
I -think- the normal kernel works for baked snack, I'll look into it in a little bit to make sure, if not I can always pull the ramdisk from baked snack and make a compatible build.
[EVO 4G Android Development] netarchy:
This is not a problem with my kernel builds, this is a problem with the wired tether app, and is a known issue by the devs. The unsupported kernel error is bogus and incorrect, all the support that needs to be enabled for wired tether is in the kernel.

Basically it's a problem that showed up after the froyo update, when the kernel base was updated to 2.6.32.

That would be awesome!! I switched to ker #4 cause I hear it's the fastest, but it was draining faster. I moved back to #5 lastnight. It's not that much better. I hear your kernel or the Kingz one works great with battery life. Anything you could do would be great.
[EVO 4G Android Development] xlGmanlx:
Net, i know its easy to make the request because it takes no effort on my part, but a Evio and Baked version of your kernels would be an early xmas for me, would be willing to donate for the cause

I've been noticing this also and it's quite annoying. It takes about 3 rings before I see the Accept/Decline screen. I have even missed phone calls because the Answer screen never came up.

I'm using 4.1.9 cfs w/ Stock ROM.

*EDIT*Reverted back to 4.1.8 cfs and its running great!
[EVO 4G Android Development] jasonleb1:
Got a stupid question. What does this uncap the FPS to?
[EVO 4G Android Development] Biofall:
Basically, there is a limitation imposed on the EVO by htc that caps the phone at 30 frames per second. They did this to allow the hdmi out to function correctly. Basically our amazing devs here worked to uncap it while preserving hdmi out, and now your Evo can have up to around 60 frames per second. This is notable when scrolling and playing games, so some people highly desire it
[EVO 4G Android Development] ms79723:
so is there a kernel that basically screams "eff hdmi out, this kernel allows 60fps"
[EVO 4G Android Development] hungry ghandi:

Running 4.1.9.1 cfs on fresh 3.2.0.0. Running great.

[EVO 4G Android Development] guitarjockey:
I flashed this onto my phone but my evo now is at 31.7fps using neocore on fresh 3.2. When I was on Cm6 I was getting around 47 so why is it that I've only uncapped my fps by 1 point?
[EVO 4G Android Development] Djay45:
Neocore always caps at around 30 fps. Use fps2d to test your fps.
[EVO 4G Android Development] d0cx:
i'm gonna test if this kernel works with the new 3.28.651.1 source floating around in the newest ROMs.

EDIT: I got boot-looped using SteelH's HTC Stock Froyo RevF. Will try again using the v4.1.9.1 and see how it goes.

EDIT: Nope... as far as I could test, these kernels are not working with SteelH's RevF ROM based on 3.28.651.1
[EVO 4G Android Development] l33tlinuxh4x0r:
I have the same results as well and I also have the same results with the stock odexed rom released by flip not fresh evo but the stock one.
[EVO 4G Android Development] Biofall:
haha I don't know if you're asking a different question, but the thing you quoted by me answers basically. The custom kernels you'll see on this site have hdmi out AND 55fps
[EVO 4G Android Development] xtravbx:
Yes! This is awesome. I decided to wing it and flash to "Revision 4.1.8-bfs edition - Fresh3 Compatible"

Seems a lot quicker!

I had never flashed a different kernel before.

I just now noticed that there is BFS and CFS.... but didn't bother to read about the difference before flashing. Stupid me... What IS the difference?
[EVO 4G Android Development] 063_XOBX:
This has to have been asked 900 times...
[EVO 4G Android Development] xlGmanlx:

[EVO 4G Android Development] xtravbx:
I'm new to this forum, but not new forums in general. It would have been just as simple to type the answer, then a snide remark.
[EVO 4G Android Development] Compusmurf:
You may be new, but it's a tough crowd, especially if you don't search first.

Now, my little dig... You should really read up on things before you just randomly flash things to your phone so you know what to expect, what other folks have had issues with, what can go wrong and how to undo your mistakes, and, of course what the other guy was implying, so you KNOW what you're flashing and why.

:)

Oh, and read post 4339.... That'll tell you everything you need to know. :)
[EVO 4G Android Development] Biofall:
Best. Post. Ever.
[EVO 4G Android Development] xtravbx:
Thank you. In my defense, I knew why I was flashing to a new kernel. I will be totally honest in saying that when I read, I totally overlooked that one said BFS and one said CFS. Probably from staring at a computer screen for too many hours.

Thanks for the help though!
[EVO 4G Android Development] Compusmurf:
Now that you've done your proper research....

I personally found CFS more stable, but the BFS felt faster.

I don't have quantitative proof of either other than I had several FC's on apps that ran just fine before. That was enough for me. :)

And um, you may understand what you did, and why. But I see it all the time here, folks flash, don't know what or why they did it other than someone else said it was great, then freak when something happens, blame everyone else but themselves.

I'm going to venture a guess, and possibly incite a flame war against me, but 1/3 of the folks on XDA have no business being here as it's a dev type forum. Based on some of the questions I see here, some folks need to read and learn quite a bit more about OS's, Linux, etc and stop flashing things "just because".
[EVO 4G Android Development] JZR:
Have you made any progress on a vpnc solution?
[EVO 4G Android Development] drizkol:

[EVO 4G Android Development] scev5:
to the laymen that means absolutly nothing
[EVO 4G Android Development] xHausx:
I know, I was just looking for an excuse to use that site. lol

Since a CPU can only do one thing at a time you need a scheduler to control how much time it spends on any one particular task. That's where CFS and BFS comes in.

CFS is an older routine that tries to divide up CPU time evenly between everything that needs it, but since it is older it has gotten so big and complex that some say it is bloated.

BFS on the other hand has only been around for about a year and is designed to work better on computers/devices that are slower. Supposedly making them more responsive.

Personally I'm using the CFS version though, to me it seemed much more consistent and smooth.
[EVO 4G Android Development] gjlowe:
Ok, I tried flashing a kernel for the first time this morning. To be clear, I am running the stock, rooted HTC_OTA_Froyo_2.2_build_3.28.651.1_(Rooted)_Deodex _signed_RevF1 ROM (which is probably my problem I am guessing?) I started with 4.1.8-bfs. I did what the OP said by wiping cache and Dalvik cache. Upon reboot, the phone would loop at the Sprint 4G screen. I tried wiping cache and Dalvik, and then flashing the stock HTC kernel but it still looped at the same spot. I went back did a factory wipe, cache wipe, and Dalvik wipe, and same result. Next, I did full/cache/Dalvik wipe, re-flashed the HTC_OTA_Froyo_2.2_build_3.28.651.1_(Rooted)_Deodex _signed_RevF1 ROM and then the 4.1.8-bfs kernel, and same result. I finally recovered by reflashing the ROM and left the kernel alone. By the way, I use AMON RA recovery 1.08.

So, what did I do wrong, or is it just that the kernels are not compatible with that ROM?
[EVO 4G Android Development] xHausx:
If that is SteelH's version of the stock ROM then it is the same one I am using, I havent had any trouble with bootlooping. Have you tried any of the other versions?
[EVO 4G Android Development] tatnai:
are you guys running armon's latest recovery 1.8.0? i've had bootlooping problems with the original toastch not wiping properly that were fixed with armon's, and many have reported the same with clockworks recovery. if you are already running armon RA 1.8.0 than I don't know what to tell you, besides the usual (check MD5 sum to make sure you don't have a corrupt file, flash the ROM again and then the kernel just in case you had bad flashes).
[EVO 4G Android Development] randymac88:
Taken from the PDF from the top listing on Google ("BFS vs. CFS"):

"This indicates that BFS is better for interactive tasks that block on I/O or user input and that CFS is better for batch processing that is CPU bound."

So, it seems to me like CFS might be better at handling multiple large tasks (e.g. opening the gallery while processing a vignette photo, perhaps), whereas BFS might be better for overall responsiveness and "interactivity".

I however am running CFS as I agree it feels smoother and snappier (??).
[EVO 4G Android Development] skydeaner:
Sorry for the late response, i killed my evo :***(

It was on the BFS build. I have tried it on several different roms with the same result. Switching to 4.1.8 fixes it every time.
[EVO 4G Android Development] sanjsrik:
I'm getting pretty bad lockups this morning, so much so I downgrade back to 4.1.8 and the lockups are gone. Was really weird, consistent lockups using 4.1.9.1.
[EVO 4G Android Development] BuddaBelly:
RevF1 uses the latest kernel source and as far as I know is not compatible with any of netarchys builds just yet.
[EVO 4G Android Development] fr4nk1yn:
I'll probably be flamed for this.

I installed CM6 nightly and Snap925mz and at 1190mhz it destroyed Quadrant, maybe too much.

So I ran 0xbenchmark on it and my ROM with CFS 4.1.9.1 at 1151mhz and was surprised the scores were slightly higher everyplace except the 3D Teapot which was 11fps higher with CM6/Snap, 21.5 vs. 32.5

Idea on if whatever CM6/Snap does for that graphics boost can be incorporated here?
[EVO 4G Android Development] Biofall:
Am I alone in thinking there should be a way to vote or for the OP to put a post that appears on EVERY page that answers basic questions to prevent re-asking?

Any update on that new kernel build with the full uncrippled bluetooth stack?
[EVO 4G Android Development] netarchy:
A clarification is in order here:

The kernel in the leaked ota is a 2.6.32 kernel, but the changed sources that apparently give it better battery have not been released, so working with that stuff has to wait until the ota is released officially and the sources for the changes are posted.

As for 2.6.34, those are based off the cm-kernel, and I've been playing with that as well, but it's not at a point where I'd want to release something publically (it's actually easier to make a CM/aosp ready build out of it than it is to make a sense-rom ready build thanks to a lot of custom stuff htc does)
[EVO 4G Android Development] netarchy:
Mine of course! ;D

Of course I'm bit biased on the subject.
[EVO 4G Android Development] netarchy:
The bluetooth stack is actually separate from the kernel.
[EVO 4G Android Development] netarchy:
Don't worry, I haven't forgotten about this, it's just been fairly busy lately so I haven't had as much time to work on the kernel as I'd like.
