I'm unable to figure out how to get audio output from my CDROM
drive to the default audio device /dev/sound0. I _can_ get sound
out of the headphone jacks on the CDROM drive but I'd rather not
have a cable hanging off the drive's tray (this is a TOSHIBA,
XM-4101TASUNSLCD on a Sparc 5).

I've tried the following so far:
(NetBSD-1.6.1/sparc; GENERIC kernel)

% audioctl -w play=44100,2,16,slinear_le
% cdplay play 1 | /dev/sound	# "Permission denied" error
% cdplay play 1 | /dev/audio	# "Permission denied" error
% cdplay play 1 | audioplay -f -c 2 -P 16 -s 44100 -e slinear_le -p line -
	# no error but no sound either
% cdplay play 1 | audioplay -f -c 2 -P 16 -s 44100 -e slinear_le -p line -d /dev/audio -
	# no error, no sound

The 'audioplay' manpage gives an example for playing a raw CD sound
file but I'm not sure how to do this as a music CD isn't mountable;
maybe with 'dd' ?
