[Linux-aus] Disabling HDMI sound

[Adam Nielsen]

This is probably a little off-topic for this list, since it's not
specific to Australia, so you might be better off visiting your
distro's forums.  But anyway since we're here...

This will generally disable onboard sound, so you probably want to make
sure that module gets loaded.  Make sure you check dmesg for any
audio-related messages, in case there's an issue initialising the audio
chip.

You don't have to worry about disabling HDMI audio, if you set your
default sound device correctly (e.g. in /etc/asound.conf) then the HDMI
device will never be used.

Consider yourself lucky - getting audio to work over HDMI is usually
the challenge!

Cheers,
Adam.
