No audio Dell XPS 9730, while the audio works just fine in the live USB Kubundu 22.04

When using the live USB, it works just fine.

Note that PipeWire is not running, it was one of the "fixes" I attempted, but it doesn't work with it running neither.

For both:

The driver shown in alsamixer is Advanced Linux Sound Architecture Driver Version k5.19.0-32-generic..

The kernel is 5.19.0-32-generic

Disabled secure boot.

...

Got it to work

While filling all of this, I gathered all the drivers I had blacklisted with no effect in the alsa.conf and realized I had not blacklisted snd-intel-dspcfg. I tried that, and audio is just fine now.

The contents of my /etc/modprobe.d/alsa.conf:

options snd_sof_pci_intel_tgl index=3 enabled=1
options snd-sof-pci-intel-tgl index=2 enabled=1
blacklist snd-intel-dspcfg

I got to say that the high standards that stack exchange has for questions are helpful in unimaginable ways. I solved the problem just because I wanted to make sure I fully documented my troubleshooting process.

Edit: Now comes the catch, I just realized that with this Kernel, I'm completely out of my depth about getting the graphics drivers to load. So, back to square one.

Install Ubuntu 22.04 LTS without internet connection, update afterwards and boot with kernel 5.19.0-32-generic.

tldr;

Unfortunately, this did't fixed it for me.

I've found out that when booting with the kernel of the live-image, the sound worked again. Didn't test all versions, but 5.19.0-32-generic worked for me. The current LTS kernel 5.19.0-46-generic did not.

To do this, install Ubuntu 22.04 LTS without internet connection to install it with the working kernel. Update afterwards. During boot, select Advanced Options for Ubuntu and then the older kernel. If this works for you, you can adapt grub to always use this kernel.
