[SOLVED] ALSA works, Pulse doesn't .. Help ?

Guide: http://wiki.archlinux.org/index.php/PulseAudio

Apparantly, Pulse doesn't work. ALSA works just fine but hell, I can use only 1 stream at a time. What could be wrong ?

Feb 10 01:45:06 arch pulseaudio[1663]: alsa-sink.c: Error opening PCM device front:0: Device or resource busy
Feb 10 01:45:06 arch pulseaudio[1663]: alsa-sink.c: Error opening PCM device front:0: Device or resource busy

Any ideas ?

Someone/something is using your sound device before pulseaudio can grab it.

Run pulseaudio -vvvv from the terminal and post the output.

Did you make any changes to any config files? Do you have OSS installed? Or any app using your sound device?

OSS is installed and as far as I know, there are no applications running which could lock my sound card. Speaking of config files .. no, it's a clean install and the only changes I've made are the ones represented in the tutorial I posted earlier.

Update: rc.conf daemon list contains mpd .. could it be that it locks the sound card before .xinitrc launches Pulse ?

I would suggest not using pulseaudio and replacing alsa with oss4,http://wiki.archlinux.org/index.php/OSS . Combined with jack that should give you what you want and is easy to configure.

SemiBz · 2010-02-11 18:33:00

Forgot to update the thread - removing mpd from rc.conf solved the problem so not sure whether it's worth switching to OSS .. I'll better ditch mpd.

Teoulas · 2010-02-11 21:57:34

If you want to keep using mpd, you can recompile it with pulseaudio support (or grab mpd-pulse from AUR) and enable pulseaudio output in your mpd configuration.

Don't ditch mpd, I'm using it with pulse. You can use mpd-pulse or simply set your .asoundrc to default output to pulse.

MPD is just a symptom of the bigger problem, your .asoundrc does not redirect apps using ALSA to use pulse instead.

Good advice.

Bad advice. Run this:

fuser -v /dev/snd/* /dev/dsp*

/dev/dsp* is OSS.

I suppose I should put this in a wiki. It plainly causes lots of confusion.

Edit: I've put the fuser command in the ALSA wiki
