Nice that it works out of the box. The FEX file does mention:

audio_pa_ctrl   = port:PH15<1><default><default><0>

So either it is floating or pulled up by default? Since it works
now I don't see any reason to block it. On the other hand once
that binding is introduced it would be nice to add it for power
management reasons.
