#1012 Samsung Intercept no Microphone Audio

[Anonymous]

Originally created by: goofee...@gmail.com

What steps will reproduce the problem?
1. Make or receive call with csipsimple
2. turn on speakerphone
3. turn off speakerphone

What is the expected output? What do you see instead?
When in call no audio is picked up from the microphone unless the speakerphone is turned on.

Please provide any additional information below.
I have used all the options for rerouting sound and have not been able to get audio from the mic without turning on the speakerphone.
this phone requires "Use Mode audio API" to get sound to come from the ear speaker.

What version of the product are you using? On what operating system?
Virgin Mobile Samsung Intercept
Android 2.2.2 Baseband EC07

Have tested with the following kernels
VM Intercept Ultimate Kernel Package v3(CrapKernel)
dcd's intercept kernel 0.9.0
Vampirefo 2.2

Arg... a samsung device that has a crappy audio driver :S

The audio hack I found for Galaxy S is based on a "relative" "bug" on the Samsung driver...
In fact the Hack for Galaxy S (that I hope already activated on your config), is based on the fact Mode_in_call route correctly things (to earpiece), and mode_normal retrieve the micro source (in fact unplug it from direct connection to GSM chipset).

Unfortunately, if they change that it may break my hack :S

Normally there is another very very cleaner way to do things... but samsung just do awful things with their audio drivers. And that's always a fight to get voice working on their device (there is two hacks just for this manufacturer!).

Normally on Galaxy S what helps is :
* Use Galaxy Hack => Activated
* Use Mode API => Deactivated
* Use Routing API => Deactivated
* Mode for SIP calls => Normal
* Micro source => default

If you can just check with these exact settings and let me know how it goes. (Be careful that for example activating Mode API will break everything else... in fact activating something is not "better" and combination of hacks may make sense)

Unfortunately if it does not help there is few things I can do :(. Maybe if you collect logs (see HowToCollectLogs wiki page, I could find some clue from logs raised by the audio driver)

using your settings I get audio from the mic but sound is output through the speakerphone.

Here is a log from the phone. it contains 2 calls where I switched the speaker on and off. in the second call I turned the speaker on and off more than once.

from all the options and combinations of options I've tried I can only get audio from the earpiece if I use "Use Mode audio API" but that prevents audio from the mic.

Ok,
Just quick note (for info): actually "Use Mode API" do Mode_in_call for earpiece routing and mode_normal for speaker routing.
So if you turn option off and instead use mode for sip calls "mode_in_call" you should get the same thing (for earpiece routing -- it will probably do nothing when you try to activate speaker however) ;).

Well, sounds the ROM you are using "fixes" the thing that made possible to have the hack I found for this family of samsung devices... at least that's what I suppose regarding the fact with "Use Samsung Galaxy Hack" you have routing to the speaker.
I guess these logs are not with the hack activated cause I do not see the try to route earpiece (mode_in_call) and then retrieve the micro by using mode_normal.

Is there other sip apps you tried that succeed in routing things correctly?

I can try to use the stock rom+kernel tomorrow. I just tried to make a log with the options you supplied but ended up crashing csipsimple when I tired to send them. I'm going to do a data reset on it and try again.

This is the first app I have even gotten the audio to come from the earpiece.

I introduced two new hack settings in latest revision :
http://nightlies.csipsimple.com/trunk/

One is to get the WebRTC implementation instead of mine that I found by an empiric way testing on many devices.
WebRTC is a project from Google, and I guess developpers has a better idea about how manufacturer (specially samsung did things). In fact their implementation do an exception just for Samsung :)... So there is a little hope it helps (main difference with my hacks is the order of method call).
So worth to try :
* Use WebRTC impl : ON
* Use mode API : OFF (does not really matter with WebRTC impl ON)
* Use routing API : OFF (does not really matter with WebRTC impl ON)
* Micro source : default
* mode for sip calls : Normal (does not really matter with WebRTC impl ON)

There is another setting I introduced to let you try it too, it's "Focus audio". By disabling it you'll disable the try to focus audio only on voice call stream.
It's done to stop any currently playing music. However, if manufacturer did weird things it could interfere and mute micro too. So if WebRTC does not help, you can try :
* Use WebRTC impl : OFF
* Use mode API : ON
* Use routing API : OFF
* Micro source : default
* Mode for SIP calls : Normal (does not really matter with Mode API ON)
* Focus : OFF

I know that there is also some secret codes on Samsung devices. Particularily : *#9072641*# (on stock dialpad) that allow to configure deeply how the device behaves with audio. I don't know if it's available on roms you are using, but could also be an interesting thing to look at.

OK I tested out everything on a fully stock sprint rom with stock kernel since for some reason I could not get the virginmobile stockrom to run.

in every test audio only came out the speakerphone

I am going to attempt to get the virginmobile stockrom running again as the sprint one breaks my GPS

Thx a lot for logs,

There is maybe some very interesting clue. I see some log that I've already seen on another Samsung device (codecOn and codecOff).

Could be interesting to activate the "Tone Hack". It was very helpful on the device where I had these logs about codecOn/codecOff, even if problem was a little bit different cause I had no sound at all in earpiece mode.
(Tone Hack ON + Samsung Hack ON + Mode API OFF).

Tried that, also tried everything else since I'm now on a full stock virginmobile rom with stock kernel.

I think for the sake of trying to get this working I am going to downgrade to android 2.1 with the squealjoy kernel which has a supposed VOIP fix.

I linked my thread on the SDX developers forum to here so hopefully someone else can continue trying to get 2.2 working. I'll report back with my findings with android 2.1

Ok so I got squealjoy2.2 running with andoid 2.1 and it is working, would it be helpful to have a log of that?

without squealjoy I was unable to get the audio to route to the earpiece

I think log will be more helpful for those how make 2.2 ROM.
I think that the problem is unfortunately linked to the way the driver setup sound routings :S and unfortunately the app can't workaround it in this case :(.

Hopefully SDX developpers will find a way to port the hack of the previous kernel in more recent ones.
If they need me to give some infos about the way the SIP app do things (actually all sip apps do more or less the same thing), just let me know, I'll be pleased to help.

In android 2.3.3 things will be more obvious (even for samsung ;) ). The android API has something more clear about a specific VoIP mode that they also use for the stock SIP application. Hopefully when samsung will upgrade their device to 2.3 they will provide a clean kernel that allow to change routing as define in android SDK.

unfortunately android 2.3 will not hit this device from what I've read. I hope that a kernel will come out for 2.2

So I can add that the kernel hack has been ported to android 2.2 but unfortunately I am getting the same results as with 2.1

you can get audio from the earpiece but the microphone wont work but once you turn on the loudspeaker the mic works

I am using the kernel referenced in comment 14 (http://forum.sdx-developers.com/index.php?topic=16144.0), which is a froyo kernel with the same hack as squealjoy kernel for eclair) but the results don't seem any different from the stock froyo kernel (audio comes from the back speaker, and if I enable mode audio API, audio comes from the earpiece but the microphone doesn't work).  Has anyone else tried that kernel and gotten it to work?

The audio layer compatibility has been significantly improved recently. Maybe this issue is already fixed with the next nightly builds (that will be produced in about one hour here : http://nightlies.csipsimple.com/trunk/CSipSimple-latest-trunk.apk )

Status: Obsolete
