The recent change acpi(4) change regarding bogus interrupts allowed me
to install Current on an old Everex Stepnote VA1500V notebook.
Everything works with two small nits regarding the sound.
The more important one is that plugging in headphone to the green
line-out jack mutes the speaker but does not provide and sound.
The mic input jack also does not record anything using aucat - I
rarely record though. The *wav file is generated for the appropriate
amount of time but has not discernible output on playback.

I do not see any hp or line-out outputs and I am unsure what to make of
the empty sel2_source.
The notebook chipset is Via based

dmesg | grep azalia
azalia0 at pci4 dev 1 function 0 "VIA HD Audio" rev 0x10: apic 1 int 17
azalia0: codecs: VIA/0x1708

***********
The Windows drivers for the same notebook use the ALC 655 azalia codec.
The ALC 655 codec appears to be in OpenBSD only under auvia driver
instead of the azalia driver

ac97: codec id 0x414c4760 (Avance Logic ALC655 rev 0)
audio0 at auvia0
***********
I found the codec specs for both the VT1708A and Realtek ALC 655 sound
drivers and can provide those (browser crashed with both 60+ page *pdf's
open)
Is there some way to have either have azalia call up the ALC 655 codec
or change the device code to call up auvia? In linux/alsa one can tweak
the codec in /etc/modprobe.d.
I debated sending this during the 5.6-beta freeze. On one hand, it
would be good to fix, but on the other, I can't imagine this is a common
problem.
Any additional info, debug outputs and trials of patches I should be
able to provide.
