Thanks for the input. I don't have any earphones but the right speaker is on the diagonally opposite corner of the computer from the pcmcia socket and when I put my ear right down on the speaker I am 90% sure the sound is coming from the speakers when dialing up in Windows.

I posted this same question to the tech support dept of the modem manufacturer but since it's Friday I probably won't get a response until next week sometime. If they say anything pertinent I will post it here.

In the meantime, I'll fool around with the Linux mixers and anything else I can find in the sound system.

Thanks,
Bill Moon
