 Posted: Wed Dec 14, 2016 4:42 am Post subject: [Solved] Audio only works one program at a time |
 |
|
I got my audio working on a fresh install, but only one program can be playing audio at once. Even within programs, for example, if I play a youtube video in firefox I can hear sound fine, but if I open up another tab and try watching another youtube video no sound comes out. My system worked fine on Ubuntu, how can I get different audio streams to mix and not cause issues?
Also, another example, if I play a youtube video with firefox and then try to play a video with mplayer I get the following error:
[AO_ALSA] Playback open error: Device or resource busy
DVB card number must be between 1 and 4

Most of the cards now allow only 1 playback at a time. There are some cards that allow more than one, but looks like it is not your case. So, if you want to have multiple applications using audio, then you have to enable "dmix" for ALSA, or install some server like pulseaudio or Jack. On my system I have Intel HDA card (snd_hda_intel driver). To enable dmix I've placed following into my /etc/asound.conf
| Quote: |
ctl.!default {
type hw
card 1
}
pcm.!default{
type asym
playback.pcm {
type plug
slave.pcm "dmix:CARD=1,RATE=48000"
}
}
|
My "HDA Intel PCH" is listed as card 1 by "aplay -l", that is why asound.conf references it. In your case it might be different card, so adjust the configuration accordingly. |

Might try this out once I grow tired of pulseaudio,

The only problem with multiple sources and alsa by way of slave, is that it doesn't sound as nice (clear,sharp,etc), since the rate is limited to 48000 which triggers on software mixing. IIRC.

Thanks for the reminder! I can confirm that the solution does work. |
