ioctl cdrommsf ( post #1)

I first made sure that I had the latest cdtool from debian. I tried cdplay and got "ioctl cdrommsf". Reading the man page on ioctl didn't help. What does this error mean?

i think that's just a basic Input/output error
first always have to tell people to make sure the external source cd playback device in alsa is not muted
and the volume is up on that device
for me the command to look at it would be
amixer get CD
see man amixer
as a diagnostic thing
try xmms with the cd audio player input plugin and see if it works and post back results

I didn't find a man page or info on amixer.
However:
epjh@EMH:~$ amixer get CD

For xmms:
epjh@EMH:~$ xmms
