Ambeo Plus: HDMI-CEC Issues

Hello

I would like to report a bug with the Ambeo Plus Soundbar. It's about HDMI-CEC.

To better illustrate the problem, here is my current setup.

NVIDIA Shield TV Pro -> Sennheiser Ambeo Plus -> XGIMI Horizon FHD.

If I now activate CEC control in the Sennheiser Smart Control app under Settings - Inputs, everything works smoothly, except that I cannot switch the TV ON with the Shield remote control. Switching OFF, on the other hand, works.

If I switch off the CEC control in the app, switching ON the projector works again. However, I then have to do without the volume control, which I definitely don't want.

To rule out whether it's the projector or the shield, I also connected them directly to each other and it works perfectly. In fact, if I then connect the soundbar to the HDMI 1 (eArc) port (shield is on HDMI 2), the soundbar blocks the projector from switching on again.

So it is clearly due to the soundbar.

Do you also have this problem? I already wrote a mail to Sennheiser Support.
