My laptop is a Huawei MDZ-WXX9X, with the sound chip Conexant CX8070, and I'm running ubuntu 22.04.
I'm encountering the following two problems:
- the sound is horrible in comparison to windows (I've
dual-boot).
- when I plug a Jack cable, the sound becomes normal, but the output comes both from the laptop's speaker and the headphones.
I've tried to assign the model of the card sound that I have to this options snd-hda-intel model=MODEL
in the file /etc/modprobe.d/alsa-base.conf
, like what they said here, but I didn't find Conexant CX8070
in /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz
.
I also tried to assign laptop
, which is the basic laptop config (default), but I still have the same problem.
here is the output of sudo lspci -v
