Grex Hardware Item 74: Help on Mac sound problem

Help on Mac Sound

Is anyone savvy on Mac sound stuff?  I've got a IIsi, running system 7.0.
I purchased a sleek new Nec Multispin 3Xp CDRom drive.  The drive works
great for data xfer, but I cannot get any sound out of it.  The DA they
supply with it ("Musicbox") seems to access the CD player okay (tracks
go up and down and reset on command), but I get no sound.  There is a
separate headphone jack which DOES have audio output, so I think the
problem is in the computer itself.
Anyone have any ideas?  I would greatly appreciate any assistance!

I could well be wrong, but I would guess that you don't play the audio
through the computer but through an audio amplifier. (Or headphones.)

Except for some of the snazzy-nifty new multi-media machines, that is
probably correct. Even those SNNMMMs have an extra stereo amp and speakers.

In the case of an external CD, the only way to hear the sound is from the
separate anolog audio output jack on the CD. "MusicBox" will control it
though, as you've noticed.

People who have internal CD Roms and are running a later version of the 
system (7.1) should be able to play sound through the Mac's audio, but
they often report difficulty. This is a common
problem which was introduced by the new sound manager. This new component
of the O/S shows its face in the form of a revised sound control panel.

If your sound control panel has a pop-up menu at the top, it's the new
one. Click on it and select "Sound In" Then click "options" and select
"internal CD" and "play through" boxes. These shenanigans are needed
to get this facility to work.

Thank you for the advice.  I appear to have an older version of the
sound manager (no pop-up menus are living in my sound control panel).

I can hook up the earphone jack via converter jacks into my stereo's
RCA input jacks, but the catch is the CDRom player does not produce
output through this jack if it detects that the computer is on.

Does this mean I am SOL? (="out of luck")

Yup
