Hi all,
Got several RPi's with Justboom DAC's dotted around the house feeding either the hifi or powered speakers. All working great - whole house sound system :D
I'm in the process of replacing the RPi/DAC/2.1 powered speaker combo in the bedroom with an RPi/IQaudio DigiAMP+/passive speaker combo. Very impressed with the IQaudio DigiAMP+. Good sound and a surprising amount of power.
However, the 2.1 speakers have a useful feature - a remote wired volume control and on/off switch. I'm aware of the possibility of using a suitable rotary encoder but while I was digging around on that topic I came across USB volume controls. So I bought this:-

(Other models available.)
At the very least I can hack it to use the (smart looking) housing, knob and cable to configure it as a basic rotary encoder. But before I go that route I want to investigate the possibility of using it as-is. I've had a good google around and there are tantalizing hints that it might be possible.
Examples:-

While I'm not adverse to a bit of soldering and hackery this type of device could be a useful solution for a lot of PiCorePlayer users.
Any thoughts/suggestions?
Cheers,
