Always reproduceable: My TV->select any SD channel->wait for tuning->select a HD channel with AC3 audio->no action, picture freezes->on My TV menu switch TV off and again on -> it works!

error.log reports: Failed to add filter (direct sound or realtek hd audio related)
No matter which audio codec or which renderer I configure, behaviour is the same.

Pls. find the logs attached, thank you in advance for checking this!
