Bug 333231 – chromium needs alsa-plugins

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Marcel Jaeschke 2010-08-17 20:40:31 UTC]

I visit http://www.html5video.org today to test the HTML5 video tag. But there was no sound. Chromium print several time the following output:

ALSA lib pcm.c:2171:(snd_pcm_open_conf) Cannot open shared library /usr/lib64/alsa-lib/libasound_module_pcm_pulse.so
[19087:19331:14334566122:ERROR:media/audio/linux/alsa_output.cc(740)] Cannot open audio device (default): No such file or directory

In fact '/usr/lib64/alsa-lib/libasound_module_pcm_pulse.so' doesn't exist on my system. So I emerge alsa-plugins and now i have sound in HTML5 videos. JUHU

I think chromium should have alsa-plugins as a dependency.

Reproducible: Always

Steps to Reproduce:
1. Visit http://www.html5video.org with chromium
2. Play the video

Actual Results:  
NO sound in HTML5 video/audio

Expected Results:  
Sound in HTML5 video/audio

www-client/chromium-6.0.490.1  USE="cups gnome sse2"

Is www-client/chromium-5.0.375.125 affected? How about www-client/chromium-6.0.472.36 and www-client/chromium-bin-5.0.375.125?

Just a guess: Do you have alsa configured to use "pulse" as the default sound device?

Sorry for the late response.
chromium-bin-5.0.375.12 only show the snap page when I enter the video page! Don't know why.
chromium-5.0.375.125 and chromium-6.0.472.36 are affected as well.

Yes, I do so. Is this a bad idea or outdated?

cat /etc/asound.conf
pcm.pulse {
    type pulse
}
ctl.pulse {
    type pulse
}
pcm.!default {
    type pulse
}
ctl.!default {
    type pulse
}

I don't think it is a /bad/ idea, but it does mean that you need to have alsa-plugins installed. Basically, your also config depends on alsa-plugins -- chromium has nothing to do with it.

This would explain why Pawel cannot reproduce the error.

Hmm, I see.
But chromium is the first application which really needs alsa-plugins. (just for me right now)

Listen like my "/etc/asound.conf" is not really necessary. If not, it's a missing dependency for pulseaudio!?
I have take a closer look on this, but this has to wait until monday.

The first sentence in this wiki article is what I'm working from. I'm not a pulseaudio user myself, so I can't comment from personal experience.

I think that it's rather your configuration than chromium that requires alsa-plugins.
