Bump. Dying to hear if anyone has come across a solution for this.
I took a Windows 7 VMs where this worked via PCoIP (sound in), and upgraded it to Windows 10, and then I couldn't do sound in. So this wasn't 2 different VMs, it was a direct upgrade and it broke. What about Windows 10 and PCoIP sound in am I missing?
Just an FYI. If you install the Teradici Audio Driver and select that device you will not get any audio through Blast.
