Issues with sound with Epos H6Pro headset

So, I got a new headset to replace the aging one I had, and plugged it in only to find that audio does not seem to work as expected. It is hard to describe, but it sounds like the center channel is being left out?
Testing the surround sound in Settings reveals that only the front left and front right channels work, and then they play in mono, not from their respective drivers.

After searching a bit, I have found someone suggesting to add the lines

load-module module-alsa-source device=hw:1,0
load-module module-alsa-sink device=hw:1,1 channels=8

to /etc/pulse/client.conf, however this did not yield any results. I am at the end of my wits, debugging audio is not really my forte.

Here is the output from aplay -l, showing that the headset is being recognized:

card 3: Audio [USB Audio], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 3: Audio [USB Audio], device 1: USB Audio [USB Audio #1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 3: Audio [USB Audio], device 2: USB Audio [USB Audio #2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 3: Audio [USB Audio], device 3: USB Audio [USB Audio #3]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

What steps can I take to debug this further?

If anyone runs into the same issue, after installing this pulseaudio profile it started behaving correctly.
