PC Compatibility Card - sound problems

I'm running an Apple Pentium 166 Dos card in my PM 8600/250. It runs flawlessly, with one notable problem - no sound on the PC side.

I've gone through the manuals, and troubleshooted everything, and nothing seems to work. BTW, I'm running 8.1 on the Mac side, and Windows 98 on the other...

Here's the weird part - tonight I was playing an audio CD on the Mac side. When I went to the PC side, I was able to achieve sound! And it *only* worked while the CD was playing (again, from the Mac side). It also should be noted that the sound was kind of gritty - not exactly how it should have been, but existent nonetheless...

Anyone familiar w/ running this card in the Mac - I've already checked the cables running from the CD ROM drive to the PC card, and from the card to the sound jack on the motherboard. Is there something else I can/should do?

I've also checked the sound setup on both sides - the Mac side has "sound enabled" in the PC Setup control panel, and according to the PC side, the Sound Blaster drivers have loaded and it thinks it has sound.

Any suggestions?

I have exactly the same problem with the same card on a 7220/200. However, in my case Windows refuses to recognise the presence of Sound Blaster hardware or drivers. But it is interesting that the same thing happens. I also get the CD audio through the PC with a gritty effect - but nothing else. I found the following in the Apple technical archives - perhaps it will help - (perhaps you put it there yourself). I don't think I understand what they mean by "the sound source must be set to CD". I'm hoping your problem might help me solve mine.

Mac OS 8.1: PC Setup Sound Issue
----------------------------------------------------------------------
TOPIC

I have a Power Macintosh 7300/200 with a PC Compatibility Card
installed, running PC Setup 1.6.4 and Mac OS 8.1. When I switch
to the PC side I don't get any sound. If the sound source is set
to CD, I can hear the audio from the PC.

The sound source didn't have to be set manually in Mac OS 8.1.
What is different?

----------------------------------------------------------------------
DISCUSSION

The sound architecture in Mac OS 8.1 is different from that of
previous versions of Mac OS. The sound source must be set to CD to be able to hear PC audio.

PC Setup used to take the setting of the sound source when
switching to the PC. When switching back to Mac OS, PC Setup
would switch the sound source back to whatever it was. This no
longer functions under Mac OS 8.1, so you must manually set the
sound source to CD for PC audio to work properly.

that's it! you solved it...

or rather, you made me solve it, with your advice.

to set the sound source to "cd", you simply open "monitors and sound" control panel, under "sound monitoring source", select "cd". so simple! now the mac is accepting sound from the bus coming from the cd, which is routed through the pc compatibility card.

gawd, that was a really easy fix. thanks again!
