I'm reporting several issues found within the Sound Profile's group switching.
1) I configured a wireless Dolby 5.1 group for the HDMI input and a different group for the Wi-Fi input.
[HDMI : Dolby 5.1ch group]

(A10 is center speaker)
When pausing Netflix 5.1 playback on the TV and then playing music on Spotify, the input switched to Wi-Fi and the group configuration reorganised as intended. This part functioned correctly.
[Wi-Fi : 2 devices group]
However, upon pausing the music and resuming playback on the television, the centre speaker's assignment was removed, causing it to function as a surround speaker.
[HDMI : Dolby 5.1ch group]

I have verified the audio output from the A10, and as surround sound is audible (not center sound), this is not a bug in the icon display.
2) Repeatedly switching inputs using the Auto-sensing and preset may cause several issues.

- The Ultra may not respond when the preset button is pressed. In the video, pressing it three times switched the screen to Spotify. Additionally, music did not play and remained paused. Pressing the play button on the screen started playback.
- When stopping music and resuming video playback, the TV audio may not output from the Ultra.
Three distinct scenarios were observed in this instance.
[Case 1]
As seen in the latter part of the video, the Ultra's screen is functioning normally, but there is no sound output.
[Case 2]
The Ultra screen is experiencing issues. Pressing the play button in WHA produced no sound; rebooting the Ultra resolved the problem.
[Case 3]
ARC ceased functioning. Switching the television on and off had no effect on the Ultra; a reboot was required.
