I don't think this is a CrewChief problem but I'm looking form some possible ideas please as I've run out of them.

I have the recently released Valve Index and pipe CrewChief to the headset speakers. Game sound is sent to my external 5.1 set up.

Everything works as expected but, for whatever reason, CrewChief messages are not always played in full and the start of the message is often missing. I'm up to date with the latest Nvidia HD audio drivers.

If I use my Oculus Rift, Pimax 5k+ (with Vive audio strap) or a standalone set of cans, everything works as expected.

Any suggestions welcome!
