Ubuntu 20.04 Pulse Audio not detecting Headset in Asus Sephyrus Laptoop

[Abraham Alvarez]

I own an Asus Zephyrus laptop ( ROG Zephyrus S GX701 Gaming Laptop, 17.3" HDR 144Hz FHD IPS, GeForce RTX 2080, Intel Core i7-9750H Processor, 32GB DDR4, 1TB PCIe NVMe SSD Hyper Drive) and I installed Ubuntu 20.04. At one point in time my headset was working (connected to USB) but about 2 weeks ago it stopped working after an upgrade. It doesn't work not even connecting it to the headphone jack. I have gone into the Settings and even though my device appears to be detected the configuration doesn't seem to take place. The audio keep coming out the standard output (speakers). It simply does not respect the settings. Even when I click on the two buttons to (TEST LEFT and TEST RIGHT) with my headset selected as the output device the sound still comes out the speakers. Is this a known issue?

I think that I am having the same or a similar issue. When I plug in a headset, some sound comes out of the headset, but other sounds come out of the internal speakers. I think that the reason for this mix instead of the behavior that the bug reporter is observing is that at some point I installed pavucontrol and set the sound of some things to go to the headset, but as new sound sources come up they seem to go to the internal speaker (e.g., I recently had a very curious issue where the phone ringing sound from skype came through the headset, but the voice once someone answered was coming through the internal speaker). I can use pavucontrol to change this behavior, but it is annoying and unpredictable. Sound sources should be universally controllable by gnome volume settings.

Abraham Alvarez - I would suggest installing pavucontrol and seeing if you can change the sound output source manually with that. If that "fixes" your issue then you likely having the same problem as me.
