hi all
yesterday i got my redhat 7.2 up and running.it had a package for palying audiocd's.its called cdp and had a text interface for a dumb terminal.inoticed a strange behavior.i was listening to the song and i gave the shutdown command..even when the system i completely halted(power down too) the cdp is still running.(i think it should as iam listening the songs still).i have a creative cdrom.i have a doubt.are there any cdroms which are programmed to behave this way.i mean which depend on BIOS may be..i didnt make anything how its running.
i dont know whether its related to kernel or not but please try to clarify me.
thanks
pavan

This isn't kernel related. Since the early days of CDROM drives in
computers, the "play audio" function is completely independent of the
operating system. If the player app or the operating system doesn't tell
the CDROM drive to stop, it will keep on playing irrespective if the
operating system is even running.
The only exception is in the past ~3 years some players can do "Digital
Audio Extraction" audio playing. This does involve software, and is
useful when you don't have the audio cable connected between your sound
card and CDORM drive.

Please learn to use word wrap, long lines are difficult to read.
This is normal processing. cdp just tells the cdrom to play, it is
then outside kernel control. You can get the same effect by starting
cdp then killing it, the cd continues to play.
