Hi,

I have two USB headsets, an HP Pavilion Gaming 600 and another one from
JMTek LLC. Both are supposed to support virtual surround sound (7.1),
only on Windows 10 for the first one, also on GNU/Linux for the latter.

My problem is that no matter how hard I tried on both Ubuntu 20.04.1 and
Fedora 36, I get only two channels. Stereo works, the mic works, but no
surround sound. Pavucontrol shows Digital Stereo (IEC958) S/PDIF and
alsamixer only shows two channels after selecting the relevant card by
hitting F6.

lsusb displays the following for the JMTek headset:
Bus 003 Device 117: ID 0c76:161f JMTek, LLC. USB PnP Audio Device
and according to the linux-hardware database, it's rather common.

If someone else has faced a similar issue, what could be the problem?
Hardware compatibility, software or some setting gone wrong? At worst,
could you suggest a reasonably priced headset that supports at least 5.1
audio (AC-3). Thanks in advance.
