Sound mute after hbbtv advertisement

[AndroidOS]

Sound mutes permanently after a "smart TV advertisement" as used in Germany (pro7, sat1, kabeleins, etc.). Observed on both, SAT TV and DVB-T transmissions. Bug appears most of the time (abt. 70 percent), but sometimes the hbbtv based advertisement works as intended and releases the sound take-over.

I assume it is a bug in the hbbtv code.

Only way to get the sound back is rebooting the TV (KD-49XD8077) as neither unmute or volume up is returning the sound. Placing TV in standby and back does also not return the sound.

This bug appeared first with Nougat.

Have you tried a factory reset?
