Sorry I forgot to explain my kernel configuration. I've built it with "device
pcm" in the config file, and also tried removing this, rebuilding, and doing
"kldload snd_emu10k1" and "kldload snd" after boot, with the same result in
each case. Sound works in Windows, btw, so I don't think it's a problem with
the speakers, cables, etc.
For the record. I think I've found the problem. Looking at the source for the
driver I'm using (/sys/dev/sound/pci/emu10k1.c), it has the PCI ID for both
an emu10k1 (SB Live) and emu10k2 (SB Audigy) defined, but this appears to be
for later development of the driver:
----------
#define EMU10K1_PCI_ID 0x00021102
#define EMU10K2_PCI_ID 0x00041102
<<< big snip >>>
static int
emu_pci_probe(device_t dev)
{
char *s = NULL;
switch (pci_get_devid(dev)) {
case EMU10K1_PCI_ID:
s = "Creative EMU10K1";
break;
/* NOTICE COMMENTED OUT CODE HERE */
/*
case EMU10K2_PCI_ID:
s = "Creative EMU10K2";
break;
*/
default:
return ENXIO;
}
device_set_desc(dev, s);
return 0;
}
----------
So it looks like the code for handling the emu10k2 chips hasn't been written
yet or something. My problem was that I'd altered this area of code to give
me more information about another problem (don't ask...) and thought that the
comment commenting out the EMU10K2_PCI_ID case was my own, and removed it.
/me smacks head
Thanks for the help everyone.
