I am experiencing some sound issues with my fresh install of ubuntu 19.10 on my Dell Inpsiron 7590. It has an ALC3254 sound chip.
The weird thing is, when running ubuntu from the install USB, the audio is working fine. After installation, the system only shows 'dummy output' for audio.
Using 'inxi -Fxz' for the installed version, showed me:
Audio: Device-1: Intel Cannon Lake PCH cAVS vendor: Dell driver: snd_soc_skl v: kernel bus ID: 00:1f.3 Sound Server: ALSA v: k5.3.0-42-generic
While the live version on the USB shows:
Audio: Device-1: Intel Cannon Lake PCH cAVS vendor: Dell driver: snd_hda_intel v: kernel bus ID: 00:1f.3 Sound Server: ALSA v: k5.3.0-18-generic
This shows the loaded driver is different and the Sound Server version is slightly different. I checked alsa-base.conf between the two, and they show no difference.
On the installed version, all commands to show soundcards I tried, show no soundcards. ('aplay -l', 'cat /proc/asound/cards', 'alsamixer', etc.)
My suspicion is that some way the wrong driver gets loaded for the device, maybe due to the newer Sound Server version? Any ideas on how I can proceed to further investigate this issue?
I also already tried some of the suggestions online:
- Appending various options to alsa-base.conf: Sound card not detected 16.04 Dell Inspiron 15 7579 (Dummy Output)
- Turning of sound in the bios, booting ubuntu, turning it back on in the bios, boot again
- Various other options, but most seem to be related to not having microphone audio. Which is not my main problem
Something which might me related: alsa-info.sh show the following error at the end of its output:

If any other information is needed, please let me know!
(edit) I currently installed Ubuntu 19.04, which is working just fine.
