My ULTIMA 25 AKTIV automatically switches to the "Optical" source even though no signal is currently being fed into it. What is the reason for this?
Possible cause: Auto-On for the optical input (Optical) is active. Auto-On also reacts to possible test signals
Solution: Switch off the "Auto On" function for Optical.
Menu path: System ► Advanced ► AutoChange ► TV HDMI / Bluetooth/ AUX/ USB / Optical ► On/ Off.
When changing sources during playback, e.g. from Spotify to YouTube, playback suddenly stops. What can I do?
Solution: Pause briefly and then press Play again.
