I've recently purchased a Male Micro-USB to Female USB adapter (OTG).
Now, I've connected my USB Headphones (w/ Microphone) but I can't adjust the volume.
When I try, It either mutes it completely, or plays at 100% volume. Also, the Microphone doesn't work.
For some reason, the 'beats audio' doesn't work either.
I have a HTC Butterfly,
Android version: 4.3
HTC Sense version: 5.5
What could be the reason for not being able to adjust volume?
