Hi,

I have a laptop with sound support provided by snd_via82c686.ko. Sound
support is not compiled into the kernel.

The PCI ID (v=1106, dev=3058) of the sound chip is recognised as being
"VIA 82C686 AC97 Audio", and the "chip" device driver is attached to it.
Because of this, a subsequent kldload of snd.ko will not notice the sound
card as it is already bound to a device at the time, and only unbound pci
devices are ever passed onto the probe routine. MFC of 1.163 of
sys/pci/pcisupport.c fixes this.

Note however that sound support is still not functioning on this laptop,
i'm working on that. I currently get:

pcm0: <VIA VT82C686A> port 0x1c50-0x1c53,0x1c54-0x1c57,0x1000-0x10ff irq 5 at device 7.5 on pci0
pcm0: unable to map interrupt
device_probe_and_attach: pcm0 attach returned 6

I'll keep you updated on that, in the mean time, is there any reason not
to MFC that patch?

Thanks,

gavin
