There are no other sound related PCI devices, and my graphics chip is
an R500 which doesn't support audio, so it must be coming from a
digital interface of SB450.

But I haven't been able to get it working under Linux.

I must be building differently, I'll translate that to
CONFIG_SND_DEBUG=y and CONFIG_SND_DEBUG_VEBOSE=y. Where is the
configure script?

Doesn't seem to have an effect, its easy to reproduce my switching a
control while music is playing.

I've tried, hotplugging the headphones has no effect whether or not
this switch is on or off.
