[SOLVED] ALSA multiple audio source playback

hesse · 2012-06-03 19:22:33

I noticed that by default alsa doesn't allow for playing from two or more sources simultaneously. For instance playing a youtube video while already playing music from mpd will result in having only sound from mpd. How can I enable playback of multiple audio sources in alsa? Thanks

Either use dmix or pulseaudio.

Set up mpd - you probably have it set up to hog the soundcard.

Thanks guys, but I already have configured MPD: http://pastebin.com/GJb5jHnv At least I think it's not the problem.

Badly. It needs to output to *dmix*. "hw:whatever" bypasses dmix, and so won't share with flash.

I put this in /etc/asound.conf

pcm.dsp {
    type plug
    slave.pcm "dmix"
}

and left the settings in mpd.conf like this:

audio_output {
	type		"alsa"
	name		"ALSA Device"
}

The mixing now works with multiple audio sources! Thank you.
