Alright, success!!!
Since it seems everything for this tuner is set up the same as for the
Hauppauge WinTV HVR 900, I figured let's set things up *exactly* the
same. So, like it's there for the Hauppauge, I added .mts_firmware = 1
to the definition of the hybrid XS em2882. And well, working TV audio!!
dmesg output this time:
xc2028 4-0061: Loading firmware for type=BASE F8MHZ MTS (7), id
0000000000000000.
MTS (4), id 00000000000000ff:
xc2028 4-0061: Loading firmware for type=MTS (4), id 0000000100000007.
So now with the attached patch, everything (analog, digital, remote)
works!

Uroš
