No audio streaming on Samsung TV

[Tumatutuma]

I've recently installed new versions of Sunshine and Moonlight for Tizen OS. For some reason, the audio is played on the host PC and not streamed to my Samsung Smart TV despite the fact that the relevant option ("Play audio on host") is disabled in Moonlight. What's really strange is that sound streaming via the previous versions of both apps worked fine with the default settings.
Does anybody know what should I do to solve this problem?
P.S. Forced switching to Steam Streaming Speakers doesn't help: there is no sound on the source and the TV.

OK, I've deleted both apps, installed new versions again (including a pre-release version of Sunshine), and allowed access to my microphone (which I didn't do before). Now sound streaming is back. The problem is solved.
