hello

which client(s) are you using? for best quality you should use the Lync plugin as this avoids the need for the audio to be redirected to the guest vm's and therefore reduces that latency and also avoids hairpinning.

This however isn't always an option for customers depending on their client end points.

I would suggest that if you have to use Lync in the VM without the lync plugin and need to redirect the audio in/out of the vm then you would have better quality from the RTAV redirection - rather than using USB redirection. But again, this isn't supported on Zero clients and so might not be an option,

post back with your client end point information and we can take it from there,

cheers

Why kind of endpoint device are you using? In regards to zero clients, we've had better success with Teradici Tera 2 devices (like the Wyse P25) that have isochronous USB 2.0 support. However, technically speaking, Teradici recommends using analog audio headsets only and not USB unless you are using their supported softphone that doesn't even work with Lync anyway.

If you're deploying unsupported configurations, you're going to have a bad time. Unfortunately the Microsoft Lync 2013 VDI plugin has a very very very small use case of using Windows with the VMware Horizon Client and is the ONLY supported configuration. Any other configuration is not supported, like any other thin/zero client, Mac, Linux, etc.

RTAV is a great product, but isn't officially supported (as I understand) for Lync although it does make the experience much much better.

Looking at your screenshot, it appears that you are using Office Communicator 2007, which doesn't support the Lync VDI plugin.  RTAV may be the only possible way to get the audio/video from your client to your OCS application inside your virtual desktop.

The Lync VDI plugin (which provides media offload capabilities) is only available for Windows clients.  Please see the attached deck for more details.
