Hi all,

I have two USB headsets, one is an HP Pavilion Gaming 600 and the other one  
is a cheap headset from a JMTek LLC. Both claim to support virtual 7.1
surround sound, only on Windows 10 for the former, on GNU/Linux too for the
latter.

The latter is shown as the following with lsusb:
Bus 003 Device 117: ID 0c76:161f JMTek, LLC. USB PnP Audio Device 
and according to the linux-hardware database, it's rather common.

My problem is that no matter how hard I tried under Ubuntu 24.04.1 and Fedora
36, I couldn't get the surround sound to work. Stereo and mic do work fine,
but I can't enjoy my movies in AC-3. Pavucontrol and alsamixer only show two
channels.

Has anyone faced a similar problem? What was your solution? At worst, do you
know a reasonably priced USB headset that can support at least 5.1 on 
GNU/Linux? Thanks in advance.
