HDMI audio out doesn't work

[Anders Sjölander]

When selecting HDMI digital output (RS780 Azalia controller) sound completely stops working (and if watching a video, it speeds up as it does when audio playback doesn't work). It works fine with analog playback and HDMI audio works in Ubuntu 11.04.

Status changed to 'Confirmed' because the bug affects multiple users.

[Peter Bulmer (peterb-catalyst)]

This was affecting me, but I found a workaround on another forum or bug somewhere:

Steps:
* Run alsamixer
* look for muted outputs
* unmute
for me it was "S/PDIF 1".

All the behaviour above matches - worked on previous ubuntu installs on the same hardware, other sound outputs worked - just not HDMI.

Still needs a bugfix I guess - so that it isn't unnecessarily muted, or at least so that it can be unmuted through the normal GUI. But a good workaround so far.

I have also tried to use alsamixer but I can't even change the S/PDIF volume. So it's probably a different issue.

I don't know if there is still someone following this, but I found out another bug thread similar to this one, but under alsa-driver package and for ATI radeon, so i'm not sure if it is a duplicate or not. I tried out the workaround suggested there and it worked on my radeon hd 4200.
