this question is reposted, and i also find the similar question with no answer from here: Ubuntu 22.04: No Audio from Wired Headphones, Detected as 'USB Audio' in Sound Settings
I installed Ubuntu on a Samsung T7 SSD (just "Linux to go"), and I have 2 machines (a laptop and a desktop both with Windows 10 on their SSDs). The Linux kernel version is 5.19.0-50-generic, and using linux-modules-5.19.0-50-generic
Here's the condition of my headphones:
| mach \ os | ubuntu22.04 | win10 |
|---|---|---|
| laptop | works well | works well |
| desktop | headphone and output detected, but can't here sound | works well |
I examined the situation of "Ubuntu 22.04 on my desktop":
- settings - sound output can detect the headphones "Headphone USB Audio" (aux interface but USB Audio). P.S. and I can hear sound through "Speakers USB Audio"
- pavucontrol can see the sound output bar dance when playing a video.
