MP 1.3 or 1.13?
Where are your log files?
1.13 of course ))
If you have MP 1.13 I can tell you that there is NO PROBLEM here with ARC.Someone can confirm my bugs of ARC with latest MP1.3?
So, it should work and all I can do is confirm with @mm1352000
I have the same action to change renderer of media and bass engine (ACTION_SHOW_VOLUME)
Please show me your settings, maybe problem is my setup
