Hello,
I have Huawei notebook (KLVL-WXXW-PCB) with Ubuntu 22.04.3 LTS installed alongside Windows. In Ubuntu, neither internal speakers nor headphone jack work. I only see Dummy Output while trying to adjust volume, but sound works with external HDMI monitor. Internal speakers work with Windows, so I believe hardware is fine and kernel driver (snd_hda_intel?) needs to be modified to fix the problem. I have submitted Ubuntu bug report back in January, but nobody touched it. So I try this list hoping for better result.
$ cat /proc/asound/cards 0 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xd03c0000 irq 64 1 [acp ]: acp - acp HUAWEI-KLVL_WXXW-M1010-KLVL_WXXW_PCB
I run 6.5.0-26-generic kernel.
Regards, Jacek Błocki
