Re: Intel HDA on Mac Pro

Could you do a simple test?  I need to see what the autoconfig detects
for pins.  To do this, type:

modprobe -r snd-hda-intel
dmesg -c >/dev/null
modprobe snd-hda-intel model=auto
dmesg >dmesg.out  # send me this output

This should (hopefully) detect which port the headphones are on.  It
won't enable sound, but it is useful for detecting pins from the bios
settings.

Also, when you said sound was coming from the surround channels, do you
know if the front output was coming from that?  To test this, reload the
driver with "model=macpro" and type:
speaker-test -c 6 -t wav -Dplug:surround51

Thanks,

Tobin
