amixer: Mixer attach default error: No such device

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.
epjh@EMH:~$ amixer get CD
Simple mixer control 'CD',0
Capabilities: pvolume pswitch pswitch-joined cswitch cswitch-joined cswitch-exclusive
Capture exclusive group: 0

Capture channels: Front Left - Front Right

Front Right: Playback 0 [0%] [off] Capture [off]

For xmms:
epjh@EMH:~$ xmms

** CRITICAL **: Unable to open display
Message: device: default

yep sound not up on CD device
amixer set CD 31

man pages and xmms broken -- hmmmmmm

ioctl cdrommsf ( post #5)

epjh@EMH:~$ amixer set CD 31
amixer: Mixer attach default error: No such device
