[Q] Speakerphone Echo on CM9/CM10? - T-Mobile Samsung Galaxy S II SGH-T989

I have mad echo on CM9/CM10, not for me, rather for the person on the other end whenever I am using speakerphone. It is only with AOSP based ROMs, not Touchwiz based ROMs. Touchwiz based ROMs work perfectly.

same problem here with echo in speakerphone mode, running CM9
same problem here, friends complaining about huge echo when i'm in speakerphone mode, they say it's their own voice they hear echoing.
i would assume this is an issue of echo cancellation missing when speakerphone mode is active.
ie. sound from my phone's speaker feeding back into the phone's microphone.
Currently running:
CM9 nightly 2012-08-19 mtd on SGS i9000 international.
with icy glitch kernel for the overclocking.
I should also note that i have installed the sipdroid app, could this interfere with the speakerphone?

The same issue was just reported to me on my Galaxy S (i9000), running last nightly build of CM10, so it's not just S2 issue.
Edit: I checked i9000 CM10 forum and found the solution. In Advanced Settings -> In-Call Volume Controls -> Speakerphone Mic -> reduced it from 31 to about 18. The other side can still hear me well, however the echo disappeared.

Did you try disabling "noise cancellation" in the dialers settings? Worked for me.

MIUI 1.1.14 Call Echo Problem

Just flashed miui 1.1.14...is anyone else having echo problems while on a call.The problem seems to be occurring on the other end of the call and only if I am using speaker phone on my end. Callers are telling me they are hearing an echo when they talk if I am on speaker phone. The echo problem did not occur on miui 1.1.7.
I flashed that same rom, last night and just checked speaker while on a call and it works for me.
Try re downloading and wipe proper then reflash, maybe something corrupted
Swyped from a galaxy far far away......
Generally most echos I hear are from 3 specific people in my call list. I have to believe that since 80% of the people I call on a regular basis have zero echo that it must be the phones/carrier of the 3 people I mentioned earlier. *shrug*
I posted a thread about this over at miui-dev and many other people have come forward saying they have the same issue. It has been acknowledged by the devs and they are looking into it for the next build.

[Q] VOIP - CSipSimple - Echo/Gnex

Many forum members use CSipSimple+GNex, but I have not been able to switch from Sipdroid to CSipSimple due to an echo issue with speaker phone mode.
I am running Stock 4.1.1 with a low-latency patch.
Anyone have some settings they use with CSipSimple so not only normal phone use, but also speaker phone work well without echo problems?
Thanks in advance!

Have you tried the latest version? I was using Sipdroid, and the built in Android SIP function, but the latest version of CSipSimple is outstanding, and better than both. Change to expert mode, and play around with the echo settings in the 'Media' section.
There are tons of options, and you may be able to fix your issues there. Also, try a new codec. Speex works well if you're calling over 4g/3g or you have high latency. What "low latency patch" are you using?

I have the latest Google Play version of CSipSimple, but still experiencing echo issues. Are there any settings you use specifically that I can check against?
Yeh, Speex is the best choice atm for 4g/3g I feel too.
The patch is this: http://forum.xda-developers.com/showthread.php?t=1777261
It takes the delay from 40ms to 18ms, but this was more critical in ICS, which had a delay of 118ms (?) I believe. I still applied it anyways.
Try turning on "voice audio detection" to on in media settings in CSipSimple to see if it helps.

No luck. Still overly sensitive when on speaker phone.

Mic levels, echo settings, audio routing settings. From what I can tell the problem might be either the Nexus has to sensitive a mic or the audio routing is wrong with the default settings in csipsimple.

Mic amplification : 1.0 (default)
Speaker amplification : 1.0 (default)
Echo Cancellation ON
Echo Mode is set to Speex
Media Quality is set to 4.. which is default.
Voice Audio Detection ON
Codecs : G729 and then GSM. Rest are disabled. I have set "Codec priority list per bandwidth" to off.. so it uses G729/GSM for all cases
I havent touched any settings in Audio Troubleshooting.. "Focus Audio" and "Restart stream when change routing" are on under those settings by default

I have a Nexus 4 and I'm having similar echo problems. The person talking to me hears themselves back with a 1/2 second delay. This goes away as I turn down the speaker volume from the earpiece. In Speakerphone mode its terrible and they can hear every word they say clear as a bell 1/2 second later. I'm going to start messing with the echo settings in expert mode. I have found that all SIP programs Vonage, sipdroid, csipsimple, and grooveIP all have this problem with the Nexus 4. Thankfully Csipsimple has more options for echo on the phone so I'll report back once I figure out what works best.
Update problem fixed on my Nexus 4. I was reading through the csipsimple bug mailing list on this issue, and one of the developers pointed to a possible way of fixing echo that completely fixed it for me.
go to csipsimple google code page in the FAQ go to audio routing troubleshooting.
Basically try the Use Mode API first (which worked for me) and go down the list till your echo is gone. To test your echo I would turn up the earpiece volume all the way and set the mic gain to about half during a call in the settings page. If the other person does not hear echo you should be good.

I'm having the same problem.... did you figure this out?
EDIT: Oops, sorry, saw you did. I'm currently using Sipdroid, I may have to switch over to CSipSimple.

Call audio quality

My parents have been complaining about call quality. Basically they cannot understand what I'm saying most or the time.
I'm running the jb nightly
Any suggestions to fix it or any or you experiencing the same problem
Sent from my SGH-T989 on Jelly Bean goodness!
I think I might be possibly having the same issue. I get complaints about call quality randomly. It's only some calls some of the time. Usually the person on the other end complains about an echo. if I hang up and call back it usually resolves it.
Is your problem intermittent or all the time?
Edit: Running stock ICS 4.0.3.
I know it. Skype quality is very fine. But the normal calls are a so bad. Open the call window -> go in the option menu and de/activate the (i dont know the word in english) "Noise suppression". Test both. After the change it should working correctly.
You can check your microphone. Do a test call with skype or some other internet call app.

Noise suppression works well on the latest CM 9.1 and AOKP builds and ICS 4.0.4 from my experience. Everything else, I can't really vouch for.

Options:
1. try different modems
2. try different kernels
3. make sure noise suppression is checked off
4. try different phone.apks
Now here is something that some dont realize but next time you are on a call and use call waiting, when you come back to the person on the original call ask if your call quality has changed. It is an issue if you go from one call to another in AOSP based roms it seems to re-create the underwater muffled sound. If you dont have this happen to you then you are lucky but I have tried this on a few of my friends phone with the same result
Edit: OP ya gotta search next time this has to be the number 1 or 2 asked question in here
I was plagued with these problems as well. No matter what rom or setup I had it never got better. Got a warranty replacement and problem solved. Hopefully it's not that but a brand spanking new device is always cool either way.

[Fix]For anyone experiencing call distortion on custom ROMs

I was experiencing the widely reported call distortion and people being unable to hear me when making calls. I think I found the fix. When you place a call, pull up the menu and turn off the noise filter. Did this and haven't had a problem since with multiple ROMs.
Sent from my SGH-T999 using xda app-developers app
This post title is confusing it makes it look like you have the fix although i have never had any call distortion is it during WiFi calls? what rom are you using....
I too was having that problem and was making all calls via speaker as the issue did not present while using the speaker. I can confirm that disabling noise reduction did the trick.
Phone (like you are making a call)
Menu Button
Go to call setting
Go to additional settings
Disable Noise Reduction
It is also being reported that capping your overclock at 1.5 eliminates the problem as well. The rom/kernel gods are working on the issue.
I've used a few ROMs ranging from Frosty to Sonic and I am now on CM10. Turning the noise reduction has worked with the distortion issue on all the ROMs I've used. My WiFi calling on CM10 works fine as well.

Woah, you should go collect your $350 then.
Flashed Wicked 2.1 a couple days ago and have not had to disable noise reduction.

bad Echo when using speakerphone

This only happens on aosp CM ROMs....people are telling me they can hear themselves talking and echoing back when I try to use the voice call speakerphone. This doesn't happen on stock ROMs. Does anybody else have this issue or does anybody no of a fix or work around???
I'm running on cm13 and people tell me they have a hard time hearing me with echo when i put them on speakerphone, and i have to get off it. I don't hear any echo of my own voice on my end. Seems this is an issue that doesn't appear to have any resolutions (not that i can find thus far...).

I am also interested if anyone has fixed this problem.
Same issue with echo on G3 VS985
I also noticed this after switching to CM 13 ROM and now with crDroid 1.5 which is based on CM 14.1.
The echo goes away for the caller when I mute my microphone, so I can still use the speaker and then unmute when I want to talk - obviously not ideal but it seems to work.
