I have pavucontrol installed and the config tab for my headset which
pulseaudio recognized, only has the options of 'Digital Stereo Output

pulseaudio did not select the headset by default, I had to manually
select it from pavucontrol.
That's not unusual, since the default is device 0, and that usually is
the on board audio. You can set it as default in the pavucontrol
output devices tab (called fallback there).
It seems that alsa doesn't support the functionality of this device (at
least I couldn't find any support). Check by typing
aplay -Lv
to see if there is a 7.1 selection for the device in the output. If
there isn't, you won't get it working under pulse beyond the stereo you
already have. It might be in development, you could ask on the alsa
user or devel mailing lists.
When I was checking I saw this in a publicity blurb,
... The G533 is for Windows PCs only, ...
... The new headset carries over the same Pro-G audio drivers, ...
Those drivers are what will create the imitation 7.1 for the 2 speakers
in the headphones, as Tim stated. They *won't* be available for linux,
so unless someone has reverse engineered them, there won't be 7.1
functionality in linux.
...
The Logitech G533 features an exceptional implementation of DTS
Headphone: X… for Windows users.
DTS Headphone: X is one of my favorite virtual surround systems…but its
implementation is somewhat up to the headset manufacturer. DTS will
work with the other company to tune the algorithm to their specific
product.

Hi stan, Ed replied in another thread that he found some info that says
that Logitech software is required to get the functionality which is not
available for Linux, so it looks like surround won't work.
I issued the command aplay -Lv and I've put the output below. The output
snippet I've supplied seems to be indicating that it thinks the headset
is capable of surround sound, but I'm not sure if I'm interpreting the
information correctly.
