Right Speaker not working Ubuntu 22.04.2 LTS

al flag

Sound only coming from left speaker on laptop. I checked balance in GUI and alsamixer. In settings GUI it is exactly in the middle, in alsamixer both left and right are at 100. When I slide balance all the way to the right in settings, I lose sound entirely. When I keep it balanced and run the sound test, only the "Front Left" test sound comes through. I have this laptop dual-booted with Win 10 and just installed Ubuntu tonight. Win 10 has stereo sound. When I plug in headphones, the sound works as expected, both channels clear. It only has an issue with integrated right speaker on Ubuntu specifically. Any ideas where to troubleshoot from here?

I had a similar problem.

For one user there was no sound using pulseaudio. I had to remove .config/pulse directory (rm -rf .config/pulse) and restart pulseaudio deamon (sudo killall pulseaudio).

The above commands partially restored my sound, meaning that now the left speaker was working while the right one was not (for the other user everything worked as it should). Next, I installed pavucontrol and ran the pavucontrol. In the interface I just changed the gain for the speakers and the right channel was working again.

I am not sure what the problem might be, but this worked for me. Previous solution by enabling pipewire made things only worse for me.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
