Hi OMs!

Interesting! I’m using Parallels on Mac OSX and running W10

When I use the soundcard directly in windows, its dropping audio

When I use the sc with the parallels as default and allocate it within OSX as 
sc, no problem!!

It seems that the issue is Parallels, passing the direct audio through results 
in dropouts.

Now having a clean signal.

Thanx Guys.
