CVS commit: src/sys/dev/pci



Module Name:    src
Committed By:   mycroft
Date:           Sun Oct 31 05:50:58 UTC 2004

Modified Files:
        src/sys/dev/pci: auich.c

Log Message:
Attempt to mitigate "fifo underrun" errors in two ways:
1) Update the queue pointers any time we get a block completion interrupt,
   not just when we hit the last block.
2) Set the "back-to-back enable" bit.
In addition:
3) Make sure we ack every block we transfer; there was a bug that could cause
   the audio layer to get out of sync.
