I, have solved the problem, I seen a Roccat Kave Stereo headset on Ebay for 29.99, so I bought it and the mic worked in my 5.1 analog headset.
It turns out the earfoam worked on my headset as well. plus if my headset breaks I might be able to transplant the 5.1 speakers over to the new headset which is like brand new.
the plug looked like an RCA jack or similar. so all is well but I have still not found any true 5.1 analog headsets… so the search continues…
