What's missing? #5

For instance, there is no indicator for current microphone input volume. I don't know how difficult this would be to implement as it uses a separate endpoint and I'm not sure which Android feature gives you nonexclusive access to the microphone.

No way currently to change the headphone jack volume (which is not the same as the monitor mix percentage)

I don't know if this is adjustable from the configuration endpoint (what ShureDroid currently uses) and/or if the audio API needs to be used.

There are a few packets having to do with EQ bands that get a "valid" response but I do not know what they do. Is it possible that band frequency or band Q could be selected? Currently, band one uses 0210h for "enabled" and 0214h for "gain", but the valid responses I believe come also from 0211h and 0213h. (Band two is 0220h; band five is 0250h; they all respond "valid" to those unknown offsets)
