After update, audio won't play through HDMI cable
Try installing pavucontrol by opening a terminal and typing:
sudo apt-get install pavucontrol
After installation, you should be able to configure your audio device with this gui.

Yesterday (June 7th) I faithfully updated a bunch of stuff through update manager (though I'm not sure what since I never read what I updated any more because I'm a bad person). Afterward, I discovered that I could no longer play audio through my tv via HDMI. The sound settings menu seems to have completely changed and the shell script that I wrote a week ago (with much pain and effort as I had never before written a shell script) to toggle between my laptop speakers and the HDMI cable output no longer works. When I type in
pactl set-card-profile 0 output:hdmi-surround
in the command line I get
Failure: No such entity
Presumably this means something with Pulse Audio changed but, while I'm learning a lot about the inner workings of Ubuntu/Linux, I'm not an expert and would love some help.
EDIT: So I noticed that
pactl set-card-profile 0 output:hdmi-stereo
seems to get everything working, so the name of the hdmi output just changed. Still, shouldn't there be a way to switch to HDMI through the GUI as well?

sudo apt-get install gnome-alsamixer
command. -
FuzzyQ almost 12 yearsPavucontrol is a graphical tool, but for configuration of pulse audio, while alsamixer, as the name implies, is a configuration tool for alsa audio.
