[Bug 1346490] [NEW] Only audio over HDMI in certain modes

 

Public bug reported:

I've hooked up my computer (Ubuntu server 14.04 LTS) to my receiver
which in turn is hooked up to my TV.

The problem is that audio only works on certain modes. For instance, if
I set the mode to 1080i60 using xrandr, audio works fine. The same goes
for 1080p25. However, when I increase the framerate on the progressive
scans on the 1920x1080 resolution the audio switches off. E.g. 1080p60
(the preferred mode) shows the video just fine,  but there's no audio.

When the computer is directly connected to the TV I'm able to play audio
despite using the preferred 1080p60 mode on the built-in TV speakers.
