***sorry - long post warning for detailed explanation! 
I used to use the app, but don’t since their blatant disregard for their clients was revealed a few years back (laid bare by Malwarebytes) - I just don’t trust them any more and have found so much material on the 'net that confirms their security is a shambles and their attitude apathetic. When malware was found on their servers instead of taking the required action they simply told clients to switch off their AV progs when using Discord. Totally unacceptable. In the end, after months of denial, they gave in and cleaned the server.
That’s why I only use them in a portable browser - the same one I used to use for Facebook before I deleted my account there a couple of weeks ago, now I no longer need it. But I’ll never install anything from Discord again. I don’t even like using it in that browser - but as it’s so popular and used by communities like this one as well as many developers, I decided to do it that way.
Anyway, to get to last night - I went through my settings on Discord and the frustrating thing was that on the microphone test tab, it was showing my strentgh well into the green - and I could hear myself in the headset, so the mic was definitely getting through to Discord, it just wasn’t being sent to others in the group.
I could hear you all - I heard @chipwich telling Freak (for my benefit) that the SRS frequency was 243MHz (iirc).
As mentioned, I rebooted the PC a couple of times and did it all again, but nix damit. The weird thing being that earlier I was on miRage’s server and all was working fine.
I have a strong suspicion that Discord set a PTT of its own choosing when I was looking through the settings. I selected to use a PTT switch, but then cancelled it so that I could have a think about which controller I wanted to use for that. I now reckon it just set something as default - I’ll check later. Shame I didn’t think of that last night. Although Discord can be fairly simple when you know what you want and where it is, I think there’s far too much garbage in it for use as a simple gaming comms utility. It’s repeatedly pestering me about this function or that function that i just have zero interest in, but never know if they are required or not or if I should use them or if they make things easier - normally I just click the ‘X’ and say 'bye 'bye to any pop-ups!
One other point - sorry for the long post - is that when we were talking on Discord while flying earlier, i was using Index, but had switched to Quest 2 for the pre-mission stuff, with the intention of going to the pico 4 for the actual mission (so as to save the battery usage in the Pico - you can just swap headsets on the fly and stay in-game). That was why I’d wanted to use SRS for comms on the server - no hassle with switching input/output audio.
All might be a merry-go-round for me on occasion, but I don’t really mind, as I’d rather feel more secure and have a bit of a dance than use stuff I don’t trust and worry about possible consequences.
