More updates: I removed nvidia drivers as described here https://askubuntu.com/a/757256/754424 . Ofc without nouveau.modeset=0 it doesnt boot.
With nouveau.modeset=0 it boots ("Software and Updates-> Additional Drivers" shows "Using X.Org - Nouveau" as checked, but I think Nvidia GPU is not up. "sudo lshw -C video" shows UNCLAIMED on Nvidia). With nouveau.modeset=0 and without "options snd-hda-intel dmic_detect=0" the system freezes on the login or immediately after login. The login screen looks kinda bad, the same as when I booted with 5.8 kernel. The above tests were with 5.4 kernel. Now I repeated the last test with 5.8 kernel. It boots, does not freeze, but speakers show Dummy output and mic is empty. (So the same as before disabling Nvidia and using 5.8) ---------------------------------- I think this means that Nvidia GPU is not the cause of the freeze but audio. The 5.8 does not load microphone so the system does not freeze. Also WITH dmic_detect=0 and 5.4/5.6 kernel the mic is not loaded so the system does not freeze. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1892714 Title: Microphone not working on HP Omen 17 Status in linux package in Ubuntu: Incomplete Bug description: I have the following laptop https://support.hp.com/us-en/product/omen- by-hp-17-cb0000-laptop-pc/26122176/document/c06411586 I cannot make the internal microphone to work. Sound->Input device gives no device list. Jack plug (pink) mic works. (The link says: HP Wide Vision HD Camera with integrated dual array digital microphone. So I guess this is the one and only internal microphone.) cat /proc/asound/card0/codec* | grep Codec Codec: Realtek ALC285 cat /proc/asound/card1/codec* | grep Codec Codec: Nvidia GPU 92 HDMI/DP I guess the internal microphone is related to this "Realtek ALC285" codec. In alsa-base.conf I had to add "options snd-hda-intel dmic_detect=0" or otherwise my screen freezes soon after boot. I tried "options snd-hda-intel model=laptop-amic" and "model=laptop- dmic" and "model=auto". The "model=laptop-dmic" shows the device in "Sound->Input device" but it loops laptop's sound output into the input.
