I'm trying to rebuild a PC for which I have no disks, and I'm struggling to find the correct drivers for the on-board sound. Any advice welcome, thanks!

According to the label it is an Optronix LA915G-ALV

Some details:

Processor
Model : Intel(R) Pentium(R) 4 CPU 3.00GHz

Computer
Mainboard : 915G/GV-87X2
BIOS : Phoenix Technologies, LTD 6.00 PG 01/21/2005
Bus(es) : ISA X-Bus PCI IMB USB i2c/SMBus

Chipset
Model : PC Partner 82915G/GV/GL/P/PL/GL/910GE/GL Grantsdale Host Bridge/DRAM Controller
Front Side Bus Speed : 4x 200MHz (800MHz)
Total Memory : 1GB DIMM DDR
Memory Bus Speed : 2x 167MHz (334MHz)

Peripherals
LPC Hub Controller 1 : Intel 82801FB/FR (ICH6/ICH6R) LPC Interface Bridge
LPC Legacy Controller 1 : ITE IT8712F
Audio Device : PC Partner 82801FB (ICH6) AC'97 Audio Controller

A generic AC97 one usually works for me.

Otherwise....Linux.

Thanks, that's sorted it!

You wont believe how long I've wasted on this. I can be quite thick sometimes...

LOL no problem, as I said, it usually works for me too!
