I am facing a problem with no sound from the line-out jack in Ubuntu 19.10 (running on Kernel 5.3.0).
The headphones jack on the front panel works well. (see EDIT below) In the sound settings I can see that the system detects well when the speakers are connected and disconnected.
I have a dual-boot with Windows. In Windows everything works alright, so it's not a HW issue. I have also tried to shut down the computer completely before switching to Ubuntu, it did not help.
I found many similar cases online and tried the suggested solutions (such as playing with sound profiles in
pavucontrol and with volume in
alsamixer), however, no luck.
speaker-test also does not make my speakers make a sound.
When I'm trying to test the sound using sound control in Ubuntu, after pressing a button to make a sound from one of the speakers, this appears in my syslog:
Feb 15 11:53:45 VIKING-ALES gnome-control-c: Failed to play sound: No such driver
I tried a few different versions of Ubuntu: I started with 18.04 and eventually ended up with 19.10. No sound in any version.
My motherboard is Gigabyte X570 Aorus Xtreme, the sound card is Realtek ALC1220, the details from
alsa-info are here:
Any help would be highly appreciated.
EDIT: The headphones jack does NOT work well. I can hear something from it, distorted, but it's not usable.
EDIT 2: The headphones jack works well. Not sure what happened earlier.
