Hi,

I'm using a Decklink duo 2 to capture 2 cameras and an old creative xifi pci to mix the sound from our mixer.
Great sound coming from the old pci xifi, may i say on the recording and streaming.

The real problem i have, is that using the xifi headphone out to monitor the sound in, i get an eco, like duplicated sound. If i use any other way to listen, like from hdmi out, the sound output is perfect.
I tried in settings/sound output, both default output(hdmi) , xifi headphones and set xifi to default output i got always the eco.

Any clues ?

Thanks

Check the windows volume mixer under the speaker icon in the lower right corner. You could have the direct source and vmix coming through. One may need to be muted.
