ASLA to OSS and back to ALSA

I'm new to linux.

I switched to OSS from ALSA to fix a glitch I was having with flash (Pandora radio). I decided I didn't like OSS, even though it fixed the error, and I want to switch back. I uninstalled OSS using "pacman -R oss" and it claimed that it reconfigured ALSA for me. Fat chance. It's not working. What do I do to reload? I've tried reinstalling alsa-utils and alsa-oss, as well as run alsaconf. I removed oss and added alsa back to the Daemon array.

Now what?

note: When I try to play an audio file, this is what I get---

aplay /usr/share/sounds/alsa/Front_Center.wav
ALSA lib pcm_dmix.c:1010:(snd_pcm_dmix_open) unable to open slave
aplay: main:608: audio open error: Device or resource busy

Perhaps this information will be useful?

Re: ASLA to OSS and back to ALSA

I checked the programs using my sound card and found:

fuser -v /dev/snd/*
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  david      4439 F.... kmix
/dev/snd/controlC1:  david      4439 F.... kmix
/dev/snd/pcmC0D0p:   david      4441 F...m juk
/dev/snd/pcmC0D1p:   david      4441 F...m juk

Which didn't seem all that strange.... but when I closed juk, my sound started working. ???

Re: ASLA to OSS and back to ALSA

It is still possible for ALSA to block itself, all on its own, depressingly. I suggest you try the enhanced dmix PCM in that thread, and investigate what PCM etc. juk is using.
