Bug Description
I've been googling this issue for 10's of hours and tried many things.
Relase of Ubuntu: 19.10
Expected outcome: Music plays on the internal speakers and headphones.
Actual outcome: I can barely hear audio using headphones with volume turned up to 150%. Absolutely nothing comes out of the speakers. (The speakers sound great under Windows 10.)
Complete alsa-info output is attached, but here are some snippets:
