Strange issue with Jabra + ThinOs + SD WAN + Citrix

Hi,

5070 Thin Clients, tested with different firmware (currently 2208 but it does not depend on this)
5070 linux workspace (tested with different version, currently 22.7.0.20.2)

Citrix 1912 LTSR CU5

Generic USB redirection

Jabra Engage 65

Citrix policies set for audio

Managing through Wyse Management Suite

When connecting to my citrix desktop through LAN, Jabra Headset works fine.
When accessing my citrix desktop through SD-WAN, Jabra Headset has very bad quality (jittering)

Nothing but the network cable changes (Same WMS config, same Citrix policies, same AD groups, same headset).

Any ideas? Thanks!
