It has been eight months with no progress on my request (I’m at a loss for words): Link
I would like to propose the following:
Please add a feature that allows setting a specific input during device startup—for example, I would like it to always default to HDMI ARC. This should be configurable in the settings, as some users might prefer the device to start with the RADIO or another app/input.
Implementing this feature should be straightforward, and it would ensure that the TV is always connected to the device when the TV starts (which also triggers the Rose to start through HDMI ARC).
