According to the alsainfo.txt, the Capture source is not "Headset mic", so the headphone can't output sound.
control.6 { iface MIXER name 'Capture Source' value 'Headphone Mic' comment { access 'read write' type ENUMERATED count 1 item.0 'Headset Mic' item.1 'Headphone Mic' item.2 'Internal Mic' } } Could you please remove the pulseaudio setting by running "rm -rf ~/.config/pulse/*", then reboot and check if the Capture Source is Headset Mic now? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1889010 Title: [Inspiron 5482, Realtek ALC3204, Black Headphone Out, Front] Playback problem Status in alsa-driver package in Ubuntu: New Bug description: I'm unable to play sound through the headphone jack on this laptop. When I try to play a wav with aplay (e.g. aplay /usr/share/sounds /speech-dispatcher/test.wav) the level indicators in pavucontrol fluctuate, but no sound results. Adjusting the volume does not help. Also, when the headphones are plugged in, I cannot play sound through the internal speakers by selecting the "Speakers" port in pavucontrol Output Devices. With the headphones unplugged, the internal speakers work fine. I tested the Ubuntu 19.10 live USB and I am able to play sound through the headphones without doing anything special (plug in headphones, select "Headphones" from the popup that appears, and use aplay as above), so the hardware itself is apparently okay. The headphones do not work when booting the Ubuntu 20.04 live USB. The problem may be intermittent as I seem to recall I have been able to use the headphones since upgrading to 20.04, but I am not sure of my recollection. I also think that in some of my tests, I was able to play sound through the speakers with the headphones plugged in (by selecting Speakers in pavucontrol) but I cannot reproduce this now. Happy to provide more information, try troubleshooting ideas, etc. Thanks.
