[mythtv-users] CEC support on Raspberry Pi 3

Sat Jul 9 14:47:49 UTC 2016

Peter, thank you, great job on this already again, it was fantastically
easy to get this far.

Mike, good catch.  I had somehow never stumbled upon Peter's apt source but
instead loaded the package using dpkg manually as instructed at
https://github.com/bennettpeter/mythtv/releases

Peter, you're right, it's something with the "playback device"  --
cec-utils now reproduces the problem.  I will play around with this some
more and figure out what the difference is.  Thank you!
