Just gave the updated zip a twirl.

Sounds are working and I can access the sound settings (previous versions caused issues for me).

Echo is still present, though (other party of the call hears their voice back echoed) via earpiece. When I switched to speakerphone echo has gone at the other end.

I've tried it both with nibbles and lightning Zap kernel with the same results.

Rom is Slim Bean 3.1, Twrp recovery.

I used my backups with full wipe to test either with noise suppression on and off.

Echo (for the other party) has improved a bit when I lowered the call volume to almost minimum.

just tried take 2 on hellybean with stock kernel echo was still present. is there any way to compare the hotcakez kernel with the others to find out what is causing the echo with all the other kernels?
[T-Mobile Samsung Galaxy S II SGH-T989] capo31:
After flashing hotcakez kernel echo was gone so I decided to switch kernels I flashed the kko kernel and echo was still gone. So does that mean that maybe something from hotcakez carried over to kko. Haven't tried nibbles or lighting zap
[T-Mobile Samsung Galaxy S II SGH-T989] Elloco305:
I think it was said that kko also gives a few no echo.

I think. :) btw I still haven't got a report from echo. Using the first fix.

I've flashed so much roms today
[T-Mobile Samsung Galaxy S II SGH-T989] capo31:
Well before any fixes I had echo on every jb rom and kernel. Then I used the tape method and I had no echo. Tried hotcakez no echo then tried the 2nd fix and it went crazy with the lighting kernel and seems to be working ok with kko except the other party say my voice cut out sometimes and I sound like I'm in a tunnel but no echo
[T-Mobile Samsung Galaxy S II SGH-T989] DupleX01:

If I followed along properly when you went to the flapjaxx kernel the echo went away, but when you flashed the zip that was posted in this thread for a no echo, it came back?
[T-Mobile Samsung Galaxy S II SGH-T989] telecom2k3:
Two weeks ago was at stock Gingerbread and OK. Went to Jedi Jelly and people complained of echo. Last weekend went back down to stock Gingerbread and OK. Went to Galaxy S2 TMO SGH-T989. SBean v12; LightningZap 3.0.49.3.2 kernel. While the general quality of audio improved (MP3) far-end talker still experienced echo. In Phone application can set global noise suppression on or off, but requires a reboot/shutdown to take effect. With "NoEcho-Take2" patch installed, data over Carrier is OK. Without noise suppression, I have no receive audio at all; not good.. With noise suppression echo persists. Echo disappears on "normal" calls with the "tape" method. Far-end talkers experience echo when local Galaxy S2 is on speakerphone. Blue Tooth OK.

FWIW.
[T-Mobile Samsung Galaxy S II SGH-T989] DupleX01:
Sorry for the confusion!

I've never flashed the zip with the flapjackxxx(h0tcakez kernel) as it was not necessary. With the h0tcakez kernel everything was fine echo wise.

I tried the zip with both nibbles and lightning Zap kernel, but unfortunately the echo was there on those despite flashing the zip.

I tried with noise suppression on and off with the same results on those two kernels.

However, after enabling noise suppression I didn't rebooted. Would that made a difference?

[T-Mobile Samsung Galaxy S II SGH-T989] krazeecracker:
Maybe we need to take the libs from h0tcakez and put them in a zip to flash. I mean all the libs. Just a thought :rolleyes:
[T-Mobile Samsung Galaxy S II SGH-T989] Thee GOC:
So on the h0tcakez kernel there wasn't an issue until you changed kernels.....were you running that with the Sbean V12? That's what is currently on my phone (with the lightening kernel it came with) and the callers I have experience echo AND I sound muffled like crazy.

I am a little apprehensive to flash the secondary 'no-echo' zip after reading of some other's complications with AOPK roms.

But I think krazeecracker might be on to something....
[T-Mobile Samsung Galaxy S II SGH-T989] skinsfanbdh:
flash the hotcakez kernel and you should have no echo. thats the only fix that is working for most people
[T-Mobile Samsung Galaxy S II SGH-T989] krazeecracker:
Just checked nibbles against h0tcakez and they use the exact same modules. Now I'm almost positive that flaps modules are modified for the call echo.

Sorry for the late response but the tape method is just a small piece of tape that covers the the hole near the headphone jack and if u use a case put a piece over the hole on the inside of the case also. As for how it looks I use a case so its not noticeable. Im using it now. I'm running lighting zap and allstar v7 with absolutely no echo

Yesterday I had echo on Jedi mind trick X3 I flashed the first revision of echo fix. Spoke on the phone now with my wife on my break and she heard no echo and heard me clearly.

I saw a post somewhere that yaldak might try to come up with a echo fix for JB. I hope so since he did come up with the ICS echo fix called diamond voice or something like that I think
[T-Mobile Samsung Galaxy S II SGH-T989] DupleX01:
Alrighty, we are getting there. :thumbup:

Richardlibeau's No echo zip contains that diamond voice library. As Elloco305 mentioned above could be, it is only for ICS/older base?

Had this problem also. Clean your cache(s) in Recovery and re-install

H0tcakez. I found it useful to remove the battery after the H0tcakez kernel

install, then boot up.

SkinsFan suggested that the KKO kernel was cleaner. I loaded that

late yesterday and share his opinion. In fact, IMHO, it is MUCH better.
[T-Mobile Samsung Galaxy S II SGH-T989] bert269:
Thanks

I just did tried KKO kernel. It was working fine. -well almost.

1) the Echo was gone, but the deep-sea, underwater-experience was back, reported from the other end of the call (I live in Seattle, but that was ridiculous)

2) the BT headset is not working for calls, music is fine - apparently this is a bug with JB (although I thought only from 4.2 onwards?)

So - sadly, I went back to 4.0.4 - tired of trying all the ROMS and having these issues.....

Then again - it's fun and it's free - that is what ROMming is all about, right?

Good luck to you guys - I'll guess I'll be back with JB once it's a bit 'cleaner' - if ever.
[T-Mobile Samsung Galaxy S II SGH-T989] grannyrogers:
Which 4.0.4 did you go back to?
[T-Mobile Samsung Galaxy S II SGH-T989] Ooshi:
If you did not know, that problem is prevelant in the rom as far as my knowledge goes.

I used Tweakwiz V2 for a day and noticed the problem of call echo.

Only fix atm is for aosp based jb roms. By using hotcakes kernel it fixes call echo.

On JB TW its still a WIP
[T-Mobile Samsung Galaxy S II SGH-T989] Elloco305:
KKO kernel is another option. Some are reporting better experience
[T-Mobile Samsung Galaxy S II SGH-T989] telecom2k3:
1) OK. Had this problem also. Turn ON "Noise Suppression", in the Phone application -> Settings. That will clear up

the distortion that the far-end listener hears.

2) No problem with BlueTooth for me. Make sure your BT registers with the new kernel, SETTINGS, then Enable BlueTooth.

Click on the BT icon left of the slide-bar to view device associations.

That is, if you wish to give it another go. You're right though, ROMs and Kernels Du Jour is a frustrating experience. These

are, after all, Smart Phones. It would seem that some emphasis should be placed on getting the "Phone" part working prior

to releasing a ROM; but to each their own, I suppose :(

As I've asserted before, the HOtcakez kernel works OK also. I had camera and S-Voice crashes with that kernel. Also, many

parameters do not seem to take affect until, surprisingly, the phone is rebooted.

Alas, the Tmo KKO kernel is dead but the sources are available. I see some interesting things in there, but I need to compare it

to other ROM source distros to be sure. There is another thread dedicated to the echo problem that I'll post to, if something

looks promising.
[T-Mobile Samsung Galaxy S II SGH-T989] telecom2k3:
Voice Quality/Echo Crap

OK. Screw it. I couldn't find sources, at least not for Sbean v12/Unicef. OK, the upper mic *CAN* do a couple of things. 1) Provide sampling of background noise for an Echo Canceller function called Comfort Noise Generation. If the called party is in a loud computer room, for instance, CNG prevents the caller from hearing noise, then silence when the remote end's echo canceller kicks in. It also provides a means to save bandwidth transmitting zero voice packets, substituting a single Comfort (Background) Noise packet instead and saving bandwidth. It also provides a much better call experience. 2) Provides an ambient background noise filter for the talker, so that the actual audio is transmitted more clearly. Loud ambient background noise (computer fans, Jet engine ramp-up, symphony orchestras) can be suppressed - like what is presented in those new Apple Iphone commercials. This is sensitive because the trick here is to suppress ambient noise, while preserving proper echo-cancellation function.

A) I've got to figure most phones don't have an extra microphone like this - simply adds cost and complexity.

B) Echo canceller S/W updates posted here work on some systems, change quality on other systems, or don't have any effect. So, this problem is likely to be something that is very phone specific, and common to the phone software, like a device driver.

C) Problem is also likely to be related to Gain control of the upper microphone, probably being too high - either by initialization or via software routine. The "tape" method solves this problem by simply blocking audio input to the microphone.

That said, I'd start with the /drivers/i2c/chips/yda165.c (from KKO) which has interesting model-specific gain control functions:

There's still another code problem when Noise Cancellation is turned off. Maybe the microphone is not initialized but the multiplexing function

(voice mic and ambient noise mic) is not bypassed entirely, resulting in distorted voice heard by the receiver. That might be more difficult to track down, but if I'd start with fixing the obvious stuff first, then see what's left over.

The bottom line is, there's something very wrong, and perhaps fishy, with most Jelly Bean sources.

Anyway, thanks for letting me spew my point-oh-two.
[T-Mobile Samsung Galaxy S II SGH-T989] richardlibeau:
Interesting post. Sounds like some work but maybe it will be corrected for good soon.
[T-Mobile Samsung Galaxy S II SGH-T989] Ooshi:
Coming back to this forum to check if there's any progress,

Just a curious question. Everyone seems to be saying it's a Jelly Bean related thing.

Now the question is, I've been switching roms from stock to CM10 to Tweakwiz to Helly to Slim and so on and so forth.

I have only noticed the problem in Tweakwiz and Slim. (Note: Version 2 of TW)

Kernel being 3.0.49-cyanogenmod-ga568844d

Current CM10 being 10-20130113-Nightly-hercules

Now, I haven't seen anyone (or maybe I just missed one or two posts) say they've tried out CM10.

I mean, I honestly hate that it chugs through the battery but it doesn't seem to have the Call Echo problem.

I've messed around with it, switching between ICS based roms and stuff.

(Mainly stock and Jedi Mind Trick and such.)

This CM10 nightly has been serving me as a daily driver and hasn't failed me yet.

It also feels like the most stable one in my opinion but hey, everyone's got a different taste.

Just wanted to share my opinion on this.

Edit:

I have been asking people around how the call quality is like before and after I switch roms.

Reports on CM10, people are giving 9/10 or 10/10 ratings on the call saying it's even clearer than the calls on stock.

Crystal Clear apparently so I'm curious why nobody else has reported this.
[T-Mobile Samsung Galaxy S II SGH-T989] DupleX01:
Just a quick status update on the KKO kernel. As I have mentioned earlier this completely vanished the call echo issue for me on Slim Bean 3.1 official. Turning the noise suppression setting on makes the calls sounds nice and clear.

After a few days battery life is balanced out nicely as well. Here are a few screenshots (I was busy so not much screen time) with wifi and 3G on all day:

CM10 DID NOT work for me. At the time, 10.1 was not available for Hercules, so don't know about that. I used Release, no Nightlies. Actually, there are a number of echo reports within their forums; just a lot more posts to go through. There are also trouble tickets opened with them regarding this issue as well.

Tried kko with slimbean and it made call quality worse for me. Will try hotcakes and see next if goo will let me download today
[T-Mobile Samsung Galaxy S II SGH-T989] Ooshi:
Thanks, it seems I didn't read quite far enough about the issues regarding the Call Echo on CM10. I guess it really does differ per T989. Or as far as what I can tell.

Edit: Sorry said something very stupid but just so people know, I have heard some people get great audio quality just with CM10 nightly build 2013-01-05.

Unless I missed something in the changelogs, I don't know what caused them to suddenly have a change in call quality there.

This further puts my suspicion on T989s being manufactured differently but hey, hotcakes is kind of relied upon and could serve you well. You should try it out. Come back once you've tried it to give your feedback to us.

That's the problem. WiFi is there when I boot up, but I lose it within a few minutes.

The label is the router, which works for other wireless connections in my house and which is sitting 3 feet away from me as I type this, is "not in range."

The phone won't let me switch to static from DHCP (save-connect greys out when I try it)

It just started a few days ago, after I switched ROMS, but the problem remains the same regardless of which ROM I use... and the problem did not start immediately with the ROM change.

I changed radios and so forth, but this problem appeared several DAYS after I did that.

I've spent hours looking for solutions (I'm apparently not the only one with this problem) but have come up with nothing.

Are there other radios/modems out there to look at or install? Can I go back to the stock radio/modem, and if so, where might that be?

(UPDATE: I reflashed the stock (VRLK3.modem)... and it didn't find wifi at all; went back and reflashed to the VRBLK3_rpm_and_modem.zip back to the same problem. Finds wifi when you boot it up... connects for a couple of minutes and then, a few moments later, "not in range." )

(UPDATE 2: fired up an old Belkin with no security, and the phone seems to be holding the Belkin signal while the Actiontec that I've been using falls off the WiFi Analyzer.

Meanwhile, all other wifi stuff in the house that's connected to the Actiontec continues to be locked on to that router with a strong signal. But on the WiFi Analyzer, it just pops up briefly, and then drops off while the Belkin stays steady.)
