Hello,

I don't know if this would be considered a 'bug', maybe more of a feature 
request?

Summary: request for multi-processing for CD devices (I think the word is 
'multi-processing' - ie. so that you can play an audio CD and browse the 
audio CD using a program such as konqueror at the same time)

Full description: At the moment, if you are playing an audio CD with one 
program and you start accessing the audio CD with another program, the music 
will stop playing.

Keywords: audio, sound, /dev/hdc , /dev/ide0, alsa, oss

Here's a little bit of system information if it helps:

I am not subscribed to the linux-kernel list (well, I was, but after I had to 
delete 100000 messages and my email account was ready to be closed, I had to 
unsubscribe) so if you could possibly cc: me if you can be bothered to or if 
you really need to.

Many thanks :-)
