Hi CJ Oster,

Indeed this device works also only with 57600 and nothing else same with the tty_reset and termios that the "normal" mplay driver is using (moncaso doesn't like it), that's why i hardcoded it in the mplay2 driver that jarod added a couple of weeks for me (thx again).

The Init byte of 0x96 was already also added there.  Honestly to tell u the truth i wasn't paying much attention into the volume knob ( i had no personal interest in it) when i was looking into the device so that's the reason why it prolly won't work now ;)

All in all conclusion there is already a driver for the Moncaso 312 V2 device called mplay2.
