With EVAL-ADAU1361 Z board, I am trying drive zeros in ADC line by muting the Aux in.
I have configured the codec for Stereo, capless out, Master configuration.
Like INN & INP, the aux in does not have a volume register to mute the aux in.
So I tried by muting the MX1AUXG[2:0] & MX2AUXG[2:0] (writing to 0x00 to locations (0x400D & 0x400B))
Still there are glitches at the line though if there is no Aux in cable connected to IN3/4 jack in.
Same persists if disable both the mixer.
Is there any way, I could mute the aux in & drive zeros in ADC line indicating there is no auxin & mute?
