Hi Forum - Using the 'Speakers Audio' source in Livestream Producer's mixer I get an audio loop (not feedback, more like a repeating echo loop). Seems like Livestream is adding an audio monitor output to the computer's sound, and this is again getting fed back in via the speaker input.

Audio source going into vMix is soundcard's Line In, and the loop doesn't occur when Producer isn't streaming. I can eliminate the loop by having Producer use Line In as it's source, but then I lose the ability to mix any other sources and/or adjust delays, so that's a big loss. Any idea of whether my theory about Producer 'feeding the speakers' holds water, and better yet what can be done about it?

Thanks!

Thanks Kelvin - I tried Producer's 'Headphone Monitor' setting on both on and off, and when Headphone Monitor was enabled the feedback was much worse (and was actual feedback). This makes me suspect my theory about Producer sending monitoring audio back to speakers - this would be a major flaw that would basically make the 'Speakers' input worthless, and there'd probably be an easy / obvious way to turn it off.

I need to look for the 'Windows Recording Devices' window since that sounds like a good place to check - I tend to get lost around all the Windows multimedia options ;)

Probably could have phrased my question better as 'What's the best way to get vMix audio into Livestream Producer'?

I fixed this problem using "speakers audio" in Livestream for Producers and then muting all audio sources except vMix and Producers in the Win 7 audio mixer. We have been streaming to Livestream using this method without any problems. Not sure why Livestream for Producers recognizes vMix video, but not vMix Audio, but this works OK.
