VDI Session crashes when using RingEX or RingCX on Horizon Client 2512 (for Linux only)

We have discovered a peculiar problem that has begun occuring after upgrading our VDI environment to Horizon 2512. We have previously been using Horizon Clients 2503, and 2506 without any incident. However, since the upgrade to 2512 and when using RTAV for our audio devices (NOT THE RINGCENTRAL PROVIDED VDI PLUGINS), both RingEX and RingCX crash the VDI connection when calls are established, or the agent changes their status in CX. We have no problems with any other audio applications. And we also don’t have any issues for users using Windows or MacOS clients.

To be clear, this issue definitely sounds like a problem with Omnissa’s Horizon Client 2512 for Linux. However, I can’t ignore the fact that this behavior only occurs when we are using RingCentral apps.

I am looking to see if there are any other Horizon 2512 customers who are using the Linux client with their Ring Central environment?

We have had a similar issue, but we found that if we use the web app versus the installed one, it works just fine.

app.ringcentral.com for EX

engage.ringcentral.com for CX

Alas, anyone using the Horizon Client 2512 for Linux exhibits the same issue when accessing the web applications as well, particularly since those sites use Horizon’s RTAV for audio, and not RingCentral’s VDI plugin.

I would very much like to speak to any other RC customer using Horizon 2512.
