To test if my Pioneer SC-LX73 works with a keyboard I tried a wired keyboard and wireless keyboard
It works with both
F4 is Vol+
F5 is Vol-
F6 is mute
...but it does not work with Flirc V1 or V2
HDMI CEC works from the Sony TV to Pioneer AVR, but the volume ramps very slow
I will be ordering the Skip 1s that would solve this, but untill then I would like a solution to easily control the Volume on the amp
