Greetings
My first post! Just trying vMix with an epiphan av.io HD capture device and I am getting video and audio into the computer but I'm having problems with the audio settings in Windows,(I think). I'm just trying to get my main stereo speakers working properly with 1 input to vMix. I have a video playing on input 1 coming from the capture device. In Windows Sound Properties I have the 'microphone' input from av.io device set as the recording source and my stereo speakers as the playback device. Problem is I can always hear the audio coming from the speakers. I thought windows should be set up to hear the output of vMix, so when I mute the audio in vMix I hear nothing but I don't see vMix as a playback device in Sound Properites, should I?? Any tips you can give me. This should be pretty basic but I can't seem to sort it out.

Also in Performance Statistics I'm getting Source Dropped values constantly increasing.

Hi Ice
Ok, I set settings/audio outputs to default like you said, which are my speakers. I closed the input 1 source and added it again using "built in audio" and now I still hear the audio out the speakers but vMix sees no audio at all. No audio shows on the audio meters. I guess I still hear it because I've set my sound recording source to the av.io 'microphone'. So as you said I have bypassed vMix by routing the 'microphone' into windows. So how do I not bypass vMix,to send vMix main output to my speakers? I guess that's the main problem.

Yes, it's usb3. It appears to windows as a camera like you said. No drivers required. Uses built-in windows usb drivers. So every time I connect it I get no notification, just like connecting a usb drive. I am adding it as a camera source from the start so that's ok. I just got a dvd player hdmi output feeding the unit which then feeds the usb3 to a usb3 hub on my computer.

Update - ok, now I'm getting somewhere. I went thru the manual and changed some settings, especially the Settings/Audio Outputs, if the Master Output and Headphones are set to the same thing (Default windows playback device), the Headphones takes precedence. So that's why I was not getting any audio shown on the meters I suspect.

As of now, the meters are working good but I'm getting audio echo. In the Audio Mixer, I can see the Master Slider and the av.io source slider. If I mute one or the other, the Master meters turn off and the echo goes away. So what's happening here to cause the echo?

Update again - Had to turn off "listen to this device" in windows sound recording microphone, that removed the echo. Now when I mute vMix, my audio on the speakers mutes also. I think that's it for now.
