if you get sound from the VIA onboard, i'd say it should work  :)  it
sounds like you need some tuning. read on.

hmm. "readonly=1". are you sure you try to hdparm the right device?
this looks like a cdrom player or so, not a harddisk. and if you have
no cdrom in the drive, it cannot test the speed  :)

other things that come to mind:

- do you boot the Low Latency kernel? 

- is the low-latency patch enabled?? (see instructions on the ccrma

- did you look at your irq settings ??? read this webpage for very
good info on irq's and lots more:

good luck, and keep us posted.
