Mic doesn't work in Gtalk on ZGB. arecord works fine, so does google voice
search. Everything works on Alex.

Noticed this with R19 build "2046.30.0" on ZGB:

1.) Internal mic seems muted with google talk.
2.) External mic works fine with google talk though.
3.) But, the internal mic responds fine to arecord.

I did a capture of the talk plugin when this was happening. Any ideas?

The capture-side files are empty, meaning capturing isn't occurring at all.

For Googlers, a plugin log file should always be created. Look in
$HOME/.config/google-googletalkplugin. You should find file(s) like
gtalkplugin-cXXXX.log.bz2. Upload the one corresponding to the call
(presumably the latest).

Not sure which errors in there are important, but there seem to be a few
about handle_capture being NULL.

http://code.google.com/p/chromium-os/issues/detail?id=29356

The first errors about PulseAudio are fine, it just means we're falling
back to ALSA. I think the "handle_capture is now set to NULL" error is
actually erroneous; from the code it looks like it shouldn't be an error
but an info message.

The handle_capture error indicates recording is being stopped a few times,
which might indicate an issue. On the other hand we can call start/stop to
test devices so this might be nothing. I don't see anything else in the log
which could indicate the source of the problem.

We could have one of our TSEs repro and investigate this further. Dylan,
can you CC punya...@webrtc.org on this? Do you have a ZGB he could borrow
for testing?

http://code.google.com/p/chromium-os/issues/detail?id=29356

I have now been able to reproduce the same issue after receiving a ChromeOS
canary update. I am currently running:

Version 20.0.1105.0 canary
Platform 2153.0.0 (Official Build) canary-channel x86-zgb_he
Firmware ZGB.03.61.0740.0062G7.010

I do not know how big of a delta it is between this version and the
previous working version, but it would be helpful if someone could
determine any CLs that might have changed to trigger this. The Gtalk plugin
when it was working before and when it stopped working now is the same at
2.8.5 but that could mean that something has changed to uncover something
in the talk plugin which would be helpful to find. I will keep looking into
this to see if our logs shed any more light on this.

doesn't work for video chats.
http://code.google.com/p/chromium-os/issues/detail?id=29356

I was able to run our internal test application and reproduce the issue
(uploaded the logfile from a loopback test entitled webrtc.txt). We seem to
be able to setup everything normally (no error is reported when choosing
the default device for capture) but once the call is started, we see
numerous logs noting that our capture thread has timed-out waiting for
samples from the soundcard. I see this on the playback side also even
though the playback is working well but this is most likely because this
was in a loopback call.

caputre snd_pcm_wait timeout //log that we see noting that our capture
process has timed-out as it has not received any samples from the soundcard.

This will take further investigation. Unfortunately I will be out of the
office next week until Thursday. But can anyone double check if anything
has changed with respect to the soundcard drivers within the versions where
it was working and not working.

Another datapoint might be good to see what the logs look like when it is
actually working to see.

Ray, can you record the same log while using the external mic? You can get
an analog headset that works with ZGB at tech stop.

It also looks like the code in audio_device_alsa_linux will ensure there
are capture timeouts if it gets back a buffer and period size > 5ms. It is
getting a 46.5 mS buffer in this run, and telling snd_pcm_wait to timeout
after 5ms, not sure that's what's causing the problem, you might have to
give me a hand building GTalk on Monday so I can dig a little deeper.

Thanks.

http://code.google.com/p/chromium-os/issues/detail?id=29356

Thanks Dylan. I will look into it further today and get others involved if
I don't make much progress. What I have found so far is that the following
call in our ALSA implmentation in the function where our recording thread
runs (RecThreadProcess( ) in http://goo.gl/w76Zr)

//return a positive number of frames ready otherwise a negative error code
avail_frames = LATE(snd_pcm_avail_update)(_handleRecord);

is returning with a 0. We are not getting any samples from the soundcard.
As you have verified "arecord -Ddefault -c 2 -f S16_LE -r 48000 test.pcm"
seems to work find where I am able to play the recorded file using "aplay
test.pcm".

I will keep investigating.

Noticed this today with "gtalk", after adding onto build "2227.0.0" on all
devices.

1.) Pressing (F8) mute key for speakers mutes audio from the mic briefly,
but then it seems to unmute. One can still hear input from external mic.

2.) But, playing an audio file or audio/video link & pressing the mute key
(F8) works fine, no audio is heard.

3.) ZGB internal mic is still unresponsive as before.

Ray,

Could you please try moving the snd_pcm_wait code after the snd_pcm_readi?
More explicitly, try snd_pcm_readi() even though snd_pcm_avail_update
returns 0.
And please also tell me what device name we are using to open the device?

http://code.google.com/p/chromium-os/issues/detail?id=29356

Just to double check, this is what I did below but to no avail:

//return a positive number of frames ready otherwise a negative error code
avail_frames = LATE(snd_pcm_avail_update)(_handleRecord);

if (avail_frames < 0)
{
WEBRTC_TRACE(kTraceError, kTraceAudioDevice, _id,
"capture snd_pcm_avail_update error: %s",
LATE(snd_strerror)(avail_frames));
ErrorRecovery(avail_frames, _handleRecord);
UnLock();
return true;
}
//else if (avail_frames == 0)
//{ // no frame is available now
// UnLock();

//maximum time in milliseconds to wait, a negative value means
infinity
//err = LATE(snd_pcm_wait)(_handleRecord,
// ALSA_CAPTURE_WAIT_TIMEOUT);
// err = LATE(snd_pcm_wait)(_handleRecord,
// -1);
// if (err == 0) //timeout occured
// WEBRTC_TRACE(kTraceStream, kTraceAudioDevice, _id,
// "caputre snd_pcm_wait timeout");

// return true;
//}

if (static_cast<WebRtc_UWord32>(avail_frames) > _recordingFramesLeft)
avail_frames = _recordingFramesLeft;


With respect to your question, which device name we are using to open the
device? I am assuming "default". Here are some valid logs:

Ray,

Two things to try out:
1) Change the code:
else if (avail_frames == 0) {
avail_frames = _recordingFramesLeft;
}

while (true) {
frames = LATE(snd_pcm_readi)(_handleRecord, buffer, avail_frames);
if (frame < 0) {
UnLock();
return true;
} else if (frames < avail_frames) {
// Put a log here.
err = LATE(snd_pcm_wait)(_handleRecord, ALSA_CAPTURE_WAIT_TIMEOUT);
if (err <= 0) {
// Log the timeout.
}
avail_frames -= frames;
} else {
// frames == avail_frames
break;
}
}


2) hack into the AudioDeviceLinuxALSA::StereoRecordingIsAvailable(), and
force it to return false, so we can try out mono recording.

Ray,
Please forget the code, snd_pcm_avail_update returns 0 is a valid case
since we are using very aggressive polling, and timeout happens due to no
data. They should not be the problems.

Sorry that I did not have time to check the logs carefully, but when I
looked at the webrtc.txt in #16, I did see the recording callbacks
RecordedDataIsAvailable(), which indicates that it gets data from the
soundcard.

Too bad that I don't have any machine to test.

Ray, could you please use StartRecordingMicrophone() to see if it does
recording?
Meanwhile, use StartPlayingFileAsMicrophone() to narrow down the issue more.

Could this be analog-AGC related? The ZGB has a separate "Internal Mix
Boost" ALSA control which is separate from "Mic Boost". "Mic Boost"
applies to a headset (which works), and "Internal Mic Boost" applies to the
build in Mic (doesn't work).

Yes, we got another set of AEC debug recordings and, unlike last time, we
have a near-end signal recorded. In the first set of AEC logs, the near-end
signals were all zero.
But currently, the signal is completely zero at the output of our AEC so we
are still investigating.

I think I know why, from the log:
AudioMixerManagerLinuxALSA::MicrophoneVolume() => vol=31
VoEBaseImpl::RecordedDataIsAvailable(nSamples=480, nBytesPerSample=4,
nChannels=2, samplesPerSec=48000, totalDelayMS=76, clockDrift=0,
currentMicLevel=31)
MaxMicrophoneVolume Microphone hardware volume range, min: 0, max: 31

It looks like the OS reports a max microphone volume as 31, which is
completely wrong. The valid range in linux is 0 - 65535. A value of 31 is
close to being muted.

Dylan, any idea? can we run alsa-mixer in the terminal in chromebook?

It might depends a bit on the devices. But usually it is 65535 for ALSA too
if I don't remember wrong. I may be wrong here, please double check it.

What units is 65535 in?

On ZGB, R19, the range for "Capture Volume"is 0 - 31, which maps
non-linearly to -16.5 to +30 dB of gain.

The "Internal Mic Boost" control ranges from 0 to 3, each step is 12dB

http://code.google.com/p/chromium-os/issues/detail?id=29356

Ray and I think we discovered the root problem today. We open audio devices
in stereo by default, even if it's a true mono device. When using a mono
codec (all the time, at the moment) we downmix before processing.

The problem is that ALSA is providing stereo channels which are near exact
inverses of each other! When we downmix (add the signals) we get a nearly
zero output. Presumably this weird stereo behavior is only happening in the
ChromeOS versions that exhibit the no-audio problem.

I've attached example left and right audio channels (16 kHz), and an image
which shows the inverted signals.

Dylan, any idea what could be causing this?

Mic is still not working on R20 beta on Lumpy with Google+ Hangouts or
Gmail Call Phones. Seems to work on first boot, but never works after
resume from sleep or after first use. This is *not* working on 2268.105 /
20.0.1132.54.
