Hi Leif! Nice work, and I'm glad to hear my post inspired you, even if
my code didn't work at all!
I'm now setting 0x05 (0000 0101) instead of the original 0x25 (0010
0101) or your 0xd5 (1101 0101), to avoid setting unknown bits, and it
seems to have the same effect (I see an about 10 dB noise floor drop
when on minimum gain with no signal).

Could you test the new value and check if you get the expected results?

Thank you!
