Hi all,
geting my sound card work has been confusing for me.
There are many forum threads, but none helps. More, maybe i've
messed up with the good config part following those instructions, who knows ...
Can somebody tell me a "linear" step-by-step method of
configuring/testing a sound card?
In my Linux box i do:
root% aplay -vv song.wma
ALSA lib pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave
aplay: main:550: audio open error: Device or resource busy
My system: Debian 2.6.18.dfsg.1-18etch1
root% cat /proc/asound/card0/codec#* | grep Codec
Codec: Generic 11c1 Si3054
Codec: Analog Devices AD1986A
root% lspci | grep Audio
00:14.2 Audio device: ATI Technologies Inc SB450 HDA Audio (rev 01)
root% lshw
...

Many questions like this can be found, but no solution (at least for
me). Thanks.
