I get the following error message from aplay:
ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
aplay: main:830: audio open error: Device or resource busy
and a different message from play:
ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
/usr/bin/play FAIL sox: Sorry, there is no default audio device configured
I'm wondering what causes this. Do you have any specific environment variable
set which defines a default audio device?
