Ok, thank you.

I may stay with the default 2.1 profile if it does not affect the front
speakers signal.

What does 2.1 mean exactly ? :

 1) It divides the signal and sends separately the low frequencies to the
Sub-woofer (LFE) and the medium+trebble to the front speakers ??

 2) Or maybe it sends the Low frequencies to the LFE, but send the full signal
range to the Front speakers ?

 3) Or finally, it sends Full signal on both Front Speakers and LFE ?

In the first case, I will miss the bass if I just have front speakers while
using 2.1 profile.

Both other cases should work without any modification.
