Oh, I can finally hear sound through the earphones by changing the capture source. Too bad the change doesn't persist after I remove and reinsert the connector. Every time that happens, I must change it to Headset Mic, otherwise there will be no sound output.
It also works when I do it through the Pulseaudio GUI mixer that comes with Xubuntu. Now I just wish the default selection could be one that works out of the box, as it was in previous Ubuntu versions. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1875249 Title: [Inspiron 11-3162, Realtek ALC3234, Black Headphone Out, Front] No sound output from earphones Status in alsa-driver package in Ubuntu: New Bug description: Starting from Ubuntu 20.04 (tested Xubuntu and Ubuntu MATE), there is no sound output when you plug an earphone/headset. The built-in speakers, on the other hand, are working properly. This is a laptop, Dell Inspiron 11 3162. I checked volume levels with alsamixer, I played with the device selection in the Pulseaudio mixer application, but nothing worked. I also tested Firefox (playing a YouTube video) and system sounds. None of them worked. The audio test made by apport-bug played no sound through the earphone.
