Hello,

In Alsa-devel Digest, Vol 205, Issue 136 there is my message on internal spekaker and headphones not working on Huawei D14 laptop. SImilar issue was reported in  Vol 205, Issue 142 (No sound "dummy output"  - snd_hda_intel on Pop OS 22.04 LTS on Acer chromebook). Is there any tool/troubleshooting guide allowing to diagnose above problem? In my cases (Huawei laptop) i guess OS does not detect speakers. Is there any way to scan hardware to find components undetected by OS?

Regards, Jacek Blocki
