(TP560) Line-in volume (and portable CDROM) question

[ross@math.hawaii.edu (David Ross)]

I've just installed a portable CDROM drive on my TP560 (a refurb
from CMS Enhancements, BTW - light and fast, though fatter than my
560!), and have patched the drive's line-out to the TP's line-in
for playing CD Audio.  However, I can't seem to get very much volume,
even with the line-in volume slider maxed out.  For example, if I'm
playing a song, and close a window, the 'closing window' sound effect
is substantially louder than the song, even though I have the slider for
.WAV files only at half max.  Any suggestions? (Other than: "Don't play
CD audio through your thinkpad...")
