Michael,

No, but its very similar to PCM-5822.

PCM-5822 audio is not as loud as my old Crystal-MM PC/104 sound card
(speaker outputs), but sound quality is good. When I plug the audio
line outs into my platinum sound amplified speakers with subwoofer 
and satellites, it sounds great. I have obsoleted TVs and traditional 
stereos. Wearable plus linux box with WinTV card is all I need. Cell
phone is next on the obsolescence list :)

> What drivers are you guys using for your sound?

Check your bios irqs and ioports and try this (SB16 driver config):
/sbin/modprobe sb io=0x220 irq=5 dma=0 dma16=5 mpu_io=0x330

Check /proc/dma /proc/ioports etc and look for conflicts.
Install ViaVoice if you want to have some fun.
