As things go, the sb16 just does not get along with the 1542cf.
I've packed up the card & speakers (still have 20+ days left
on the refund).

Possibly, another manufacturers brand of sound card will get
along with the 1542, I'm open to suggestions on other brands.
But, I need my scsi tape back-up to work, and the CD is really
for accessing photo cd's, so the sound support can wait.

This weekend was not without loss; I did learn about kernel
patching.

Thanks again.
