Bug Description

Sometimes in 14.04 I don't have any audible sound. Checking volume applet > Sound Settings I can see that output is set to S/PDIF. Even though the audio previously was through HDMI. Switching it back to HDMI makes the sound audible again.

I have no speakers connected either through analog or S/PDIF. Only HDMI.

After initial install, it was set to HDMI.

Why does this happen automatically?

I usually manually turn off the monitor/TV after I put the computer to suspend. Or if I don't do it manually, it will turn off automatically after a while. Exactly what state it's in, I have no idea.

From maybe 20 suspends I have seen this issue twice.

I followed the guide and could see in the log that analog was selected. Switched back to HDMI before killing pulseaudio. I'm not sure on which output was used before I killed pulseaudio the first time though and I'm not sure if that matters?

I have never selected anything else than HDMI manually though.

Changing back to new.. and can also add that it still happens even after the wave of updates that has been coming since my original report. Fully up-to-date as of right now and after the reboot, the audio was at analog instead of HDMI.
