I checked multiple solutions and nothing seems to work for now.
I recently changed the screen (Gigabyte G32QC) on my xubuntu (20.04) machine and since, i don't have sound anymore. When checking pavucontrol it says "no cards available for configuration" and I only have "dummy output".
It seems like i'm not running on intel snd. Here's what i get when calling lspci :
desktop:~$ lspci -k | grep Audio -A4 00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10) DeviceName: Onboard - Sound Subsystem: Dell Cannon Lake PCH cAVS 00:1f.4 SMBus: Intel Corporation Cannon Lake PCH SMBus Controller (rev 10) DeviceName: Onboard - Other -- 01:00.1 Audio device: NVIDIA Corporation GP107GL High Definition Audio Controller (rev a1) Subsystem: Dell GP107GL High Definition Audio Controller 02:00.0 Non-Volatile memory controller: Toshiba Corporation Device 011a Subsystem: Toshiba Corporation Device 0001 Kernel driver in use: nvme Kernel modules: nvme
Also when i try opening Alsamixer i get
cannot open mixer: No such file or directory. Same with the -c option.
I run a Dell precision 3630 if it can help.
Thanks in advance !
