Hi Nik,

Without the Acpi patch in my kernel build I was going nowhere on the sound
problem with my vaio (FX401), but your mileage may vary.

The cause seems to be, the Vaio FX series has got some irq routing issues,
sound is allocated an irq of 7 instead of 5.

The apci patch I used seems to fix this issue and detects the southbridge
Via chipset stuff correctly. I downloaded the 2.4.20-pre8 kernel and patched
against the kernel tree, compiled and installed.

I now have Debian 3.0 running with sound (ESD, Arts) etc .... I also had to
change the permissions on the /dev/esd /dev/mixer also under Debian to get
it to work, otherwise KDE would moan 'Permission Denied'.

However, Slackware 8.1 worked straight out of the box (dont know what voodoo
was built in to its tree), and also gets around bios hang on reboot.

Hope this helps.
