Only "Dummy Output" appearing for audio in Ubuntu 22.04 and 22.10

ml flag

I recently purchased an Intel NUC Laptop and switched it over to Ubuntu (originally 22.04 LTS, and now 22.10 trying to solve this issue). It seems that Ubuntu is not able to find any audio device on this laptop (when it was briefly on Windows 11 it worked), and in the settings it just says "Dummy Output", and no audio will play.

I have tried these solutions and they did not work.

I also ran: inxi -SMA

``` System: Host: nickt-LAPRC710 Kernel: 5.19.0-26-generic arch: x86_64 bits: 64 Desktop: GNOME v: 43.1 Distro: Ubuntu 22.10 (Kinetic Kudu) Machine: Type: Laptop System: Intel Client Systems product: LAPRC710 v: M65781-403 serial: Mobo: Intel model: LAPRC710 v: M65981-402 serial: UEFI: Intel v: RCADL357.0056.2022.0706.1057 date: 07/06/2022 Audio: Device-1: Intel driver: N/A Device-2: Intel Alder Lake PCH-P High Definition Audio driver: sof-audio-pci-intel-tgl Sound Server-1: ALSA v: k5.19.0-26-generic running: yes Sound Server-2: PipeWire v: 0.3.58 running: yes ```

EDIT: re-installed 22.04, re-ran command and got this:

System:

  Sound Server-2: PulseAudio v: 15.99.1 running: yes
  Sound Server-3: PipeWire v: 0.3.48 running: yes

So presumably it's not that the driver is missing?

I noticed that the first audio device has N/A for the driver. Could this be the issue?

EDIT: added output of alsamixer

*I also don't believe the camera is working with Ubuntu either, the "Cheese" application cannot find the camera, if that might be relevant

Update:

Ran alsa-info and got this output:

Thank you!!!

Same problem here. I am not sure if an upcoming sof firmware will fix this. https://github.com/thesofproject/sof/commit/c91326bda26673948f64927cd28fab1c79f2f5d6

I don't know if this works for you, but it did for me with similar problems. Launch the Volume control, go to Configuration and set the profile to both input and output (mine was set to input only).

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
