Public bug reported: I have an extremely frustrating problem with Ubuntu 16.04.1 LTS 64-bits on my Dell E7450 laptop: when I connect a TV over HDMI afater resuming from standby, the sound is 2x as slow, and everything else, e.g. video playback, is dragged down to slow-motion.
For example, testing audio via Speaker Testing goes "Frooont Leeeft" in a low-pitch male voice (the normal is a crisp "Front Left" in a female voice"). Reproduction steps: 1. Connect laptop to TV over HDMI cable 2. Go to All Settings -> Sound and select to "Play sound through" HDMI/DisplayPort audio 3. Play a video and ensure the playback is at normal speed and the sound comes out of the TV. 4. Suspend the laptop. 5. Resume the laptop. 6. Play the same video again. Actual results: the sound and video look slow-motion, at about 50% speed. Go to Test Sound, and Front Left will sound like "Frooont Leeeft". This is super annoying because I have to close all my applications and reboot every time I want to watch a movie through my TV.
