I was using Ubuntu 20.10 on an asus x555 laptop, amd64 and amd graphics, Conexant onboard sound
All sound quit. Working one day, not the next. I MAY have updated, cant remember.
Before its suggested, my speakers are all on, and plugged in and volumes cranked up.Double checked. I’m not a newbie but not a programmer, using Linux for 15 years.
In clementine (or several other apps) they believe they are playing sound and have pretty equalizers showing it. going to PAV it has the meter that also shows it believes it’s playing sound. alsa-mixer levels are all good, and unmuted, and it correctly detects my devices (including the external when plugged in) and i have tried all of them with no success. On the connected hdmi monitor with speakers, the laptop build-in speakers, the laptop headphone and also an external usb sound card i tried all have no sound.
I purged and reinstalled alsa-base, and all alsa parts, gstreamer parts and linux-sound-base. still no sound. dpkg reconfigured each one, still no sound. also the alsa-base reload. (side note had to dpkg-reconfigure gdm3 after that since i think i broke it, it wouldnt restart)
if I boot to kubuntu live usbstick, it works well, playing sound happily, as expected, all with the same files I was trying from my HD.
I upgraded to ubuntu 21.04 hoping for a reinstall of key sound parts but alas, still no sound.
I have been on GDM3 and I just installed xfce, and it works wonderfully, but does the same thing, indicates sound is playing on the meters, but no sound.
Kubunto live works and I’d just install it but cant risk loosing the HD on the install.
Any suggestions for some base level sound handling I can troubleshoot or replace to make this usable?? Thanks.
