I just got a new laptop (ASUS GX501G), and Ubuntu 19.10 is having sound problems. It will not play sound through the speakers or through the headphones. The microphone does not work either. In the 'Sound' portion of the settings, it seems to be recognizing the speakers as an output device properly. Additionally, when I plug in headphones or connect a bluetooth speaker, it recognizes the device change and swaps the icon, name, and settings profile. When I dual boot back into Windows 10, the sound works as expected.
Strangely, the speakers will work briefly for roughly 2-3 seconds after I disconnect a bluetooth headphone device. The bluetooth headset powers off and the speakers play music while it decides where to route the audio next.
I have tried opening
alsamixer in the terminal and raising the volume and un-muting the different channels with no success.
Another very odd thing: when I plug in my over-the ear headphones it is picking up a very faint signal to a local Mexican radio station, not sure of the exact frequency or if it's FM or AM. The high production value makes me guess FM. I've never experienced that in a computer before...
