I forgot to tell you that I never see any dialog when I plug the earphone. It's a feature of some desktop environments, right? I have never seen it in Xfce.
The capture source changes to "headphone" every time I plug the earphone, and when that happens, there is no sound output. Changing it to any other source makes the sound work. I don't remember how it worked in previous versions of Ubuntu. It just worked. I never had to worry about switching the capture source in order to have sound. If you think that's important to know, I can try a live ISO of 18.04 and report back what I find. -- 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.
