OSS is essentially replaced by ALSA, try using `aplay` to play sounds
through the ALSA interface. /dev/dsp is still present because of ALSA's
OSS emulation.
Having said that, the device or resource busy message probably means
that your card doesn't support hardware mixing (playing >1 sound at
once) and if you close all other apps using the soundcard it'd work.
A I know my card must support some kind of mixing - before updating my
kernel using "yum update" I was able to use (sometimes) VoiP and heard a
'ping' when somethign was happening in one of my terminal windows. So that
should work fine actually...
Also I am not aware of anything that uses this soundcard. Is there any way
to find out which code, program etc uses the device? And what device is
actually used? Is it /dev/dsp or /dev/snd/ or something else?
Thanks,
Alex
