Arch Linux

I can't reproduce this; while the speaker selection box is grayed out, it says "Default speakers" and "Play test sound" works as expected. I'm also able to hear audio in calls.

The libffmpegsumo.so we ship is compiled with full codec support so that shouldn't be the problem.

Please test if Google Chrome has the same issue. Also check if it could be a firewall issue:

Good morning Evangelos,

I have the same setup in the sense that it is grayed out, but the play test sound does not work.
I do have 2 sound cards on my system, 0 being HDMI and 1 being the regular one. So I have setup .asoundrc like this:

[11:26] freiheit:~% cat .asoundrc
pcm.!default {
type hw
card 1
}

ctl.!default {
type hw
card 1
}

I am not sure if this is related.


For the positive test: Just using firefox + google talk plugin on the same machine works perfectly, I am seeing all speakers and sounds works in the test, as well as in the call (i.e. it is not a firewall problem).

Regarding the link: My connections works fine, video works, the other party can actually hear me. I can see by the bars in their icon that they are speaking, I simply do not hear anything.

I will try to give chrome a try to compare.

Just tested google-chrome with the same result.

Started from the 64 bit rpm using:

./opt/google/chrome/chrome

and also tried

LD_LIBRARY_PATH=$(pwd)/opt/google/chrome:$(pwd)/opt/google/chrome/lib ./opt/google/chrome/chrome

Both times the sound card is grayed out, test sound does not play

I also realised that the camera is grayed out, but this is also the case in firefox.

However I saw one difference: when pressing "play test sound" it changes to "playing" in firefox, however the text stays as it is in chromium/google-chrome.

Can you test without the .asoundrc file to see if the "Play test sound" text changes on click?

Perhaps also try using an alternate .asoundrc file like the one below:

Without asoundrc: Changes to playing, but I do not hear any sound -> I suspect it takes device 0 and plays to HDMI output

Plus errors without .asoundrc:

With the suggested asoundrc it WORKS! I have to read into alsa, what the differences are here, thanks a lot for the hint!


I don't know in which version it changed, but maybe it was not related to chromium itself, but to alsa. However I remember that trouble started at the time that chromium began to have native client support.

I will now also test without the google talk plugin, because I saw that I re-enabled it for testing some days ago.

It also works without the google talk plugin - so the problem was indeed in my .asoundrc - thanks again for helping me out!

Where's the donate to great support button?

Glad it works for you now. ALSA configuration has always been a black box to me. :)

I'll go ahead and close this task.
