I've found workaround.

1. Reset settings of CEC to Defaults
   
2. Switch source to the device on startup = OFF
   
3. Devices to power on during startup = None
   
4. Devices to power off during shutdown = None
   
5. Send "Inactive source" command on shutdown = OFF
   
6. Save changes and reboot R-Pi

Any news on that?
The linuxbased PVRs called 'Dreambox' do control the volume of the connected AVR or TV from the beginning. I don't want to force you to implement it, I just want to show you, that IMHO it is absolutely possible w/ linux. 🤓

I can't believe this hasn't been fixed after 3 years with more and more TVs supporting it (the list needs an update)... Anyway, here's my workaround:
Write this into your keymap:

xml:
<volume_up>System.Exec(/storage/cec-volup.sh)</volume_up>

<volume_down>System.Exec(/storage/cec-voldown.sh)</volume_down>

Write this into /storage/cec-volup.sh:

Code:

#!/bin/sh

echo volup | cec-client -s -t t -p 1 -b 0 -d 1

Write this into /storage/cec-voldown.sh:

Code:

#!/bin/sh

echo volup | cec-client -s -t t -p 1 -b 0 -d 1

Lastly make sure the two scripts are executable.

There are some issues with this through:
- It changes the CEC device name to CECTester.
- It's slow.

Please allow me to hijack this thread: 

Is the other way round possible? 
Disable volume control of AVR using an IR remote? 

I just want the remote to power on/off the attached AVR and TV, but the remote shall NOT send any other signals to the AVR.
