Interesting. I shall have to compare that with the CS5510/20 VSA1 tree I
have here (which isn't under LGPL)

The 5530 in native mode only generates SMI. I've always felt however that
if you make the buffers big enough you ought to be able to drive it off
the 1KHz timer tick by polling. Interesting project.
Looks like somebody did it already. I will try it as soon as I can.

Hi Rafał,
It seems that you're already using irq 9 for another device, and as Alan says
the cs5530 audio device doesn't seem to do irq sharing. It seems to me that you
need to go into your BIOS settings at startup and tell the device to use an irq
line that's not already in use by some other

Might be worth setting the IRQ to sharable. I've never seen a 5530 with
the sound IRQ shared so I don't know if that works and is a valid
configuration for the VSA firmware
The relevant patch is below. Please give it a try.
