Yes, reverting fixes seek/startup time.

If you're concerned about the popping noises, I switched soundcards to
an old SB PCI128 I had lying around (some form of Ensoniq chipset), and
I don't seem to have them anymore. I had several identical SB16's
around, every single one of them had clearly audible popping
noises.

Your patch in kern/59208 *did* seem to lessen the popping noises on the
SB16 cards significantly, though it didn't remove them completely.
