--- Comment #4 from Alex P. <alex at znirp.de> ---
I've attached a dmesg output. See also details button from the attachment.
The system I use, is a home-made HTPC with Ubuntu LTS 14.04 and actually the
following kernel: 4.4.0-040400rc8-generic

Components:
Mainboard: ASRock B85M-ITX
CPU: Intel i3 4150
RAM: 2x 2GB G.Skill F3-12800CL9-2GBNQ
SSD: Kingston SS200S3
DVB: Digital Devices Cine-S2

TV: Samsung UE46ES5700
AVR: Denon 1912 


My HTPC is running Kodi (XMBC) with TVHeadend as PVR Backend.
When a scheduled timer (PVR) starts, my HTPC is turning on by RTC (only the
HTPC).
The problem now is: When I decide to watch TV or a movie (while the timer is
still running), I turn on the AVR and the TV.
Now I mostly get no picture and sound. Sometimes I get a picture but no sound.

Hopefully you can follow this description of my problem.
If you need further information, please let me know.
