No sound out/ input with VMare Audio Tap devices on physical View Agents

blazilla — Mon, 23 Mar 2020 07:51:21 GMT

Dear all,

I'm facing an interesting audio problem with Horizon View on physical agents. Due to COVID-19 we deployed Horizon View at different customers, partially on physical desktops. When using the VMware Virtual Audio (devTap) and VMware Virtual Microphone devices für audio out- and input, the user has not sound in- and output at his desktop. When selecting the correct devices, the user has sound in- and output on the physical desktop, but poor quality when using the same desktop using Horizon View. My guess: When using other devices than the VMware devices, RTAV is not used.

Any hints on how to deal with this? Changing the devices remote is not possible because the user only sees a "Remote Audio Device".

Thank you for this hint. Unfortunately this does not fit to my problem.

I ran into a similar scenario last week over our 7.5.2 environment using external direct connections to physical machines. At the end, i could run a webcam, mic with audio through my Horizon direct connection beautifully using a 3-arm external UAG setup.

How I got it to work.

Physical on-prem workstations:

Uninstalled the Horizon agent - reboot

Installed the latest Horizon agent 7.12.0, pointed to the first connection broker FQDN, current user ->install options Core, USB redir, Real Time Audio-Video (RTAV) and VMware Audio - reboot

Logon - Test your speakers and mic first- adjust volumes

Connection Broker:

Create a new test manual pool

Add machine and add user

Setup option for Blast or RDP or PCoIP (worked with any protocol)

Home user machine:

MIC/Sound issues? Windows device manager -view-> show hidden devices->uninstall all the Audio input/output and Sound devices then reboot

It will re-add the needed sound devices

Use latest full client horizon client from VMware

Observations:

RDP kept same sessions local or remote, blast did not. Blast logged off your current session and closed all of your applications.

Lots of options to tweak under the physical gpedit.msc ->Computer-Administrative Templates - VMware Blast (etc)

Installed the local Horizon admx on the physical workstations to gain Horizon options to enable "Screen blanking" to prevent anyone viewing my RDP onsite.

Give that a run.

If the physical machine with the Horizon Agent installed is not running Windows Enterprise edition, sound won't work.
