Mike suddenly stopped working?

Heh, we can communicate and transmit data with satellites in interstellar space using 1970s technology. We've had working voice coms for the masses over public Internet since, what, 1994? First used Roger Wilco for games late 1999. My high school students can't imaginative a time without these tools, because they've never lived in one...

Thus, one ought to expect a simple, no fuss solution for speaking with three other players in a new game, right? Surely all mistakes have been made already, and there's no way to frak up such a basic thing anymore...

Tell that to Psyonix, the makers of Rocket League, who haven't been able to make it work for 3 platforms.

That's because there isn't a link for how to make average people understand genius.

If you do use Morse code, please format messages using the ACP 124, and stick to regular ACP 131 signals to avoid confusion, being common standards and all. Also easy to learn. Localized formatting and signals always makes a mess of things. If using macros or scripts, ACP 127 is helpful too; it's mostly ACP 126 (radio teletype) for automated (originally tape) signalling. ^_~

As for interpretative dancing... I have a feeling dance moves isn't Bioware's forte. 

No killa works, just not in the summer,  how else could he have afforded all those damn andromeda points?

Have you checked in Origin 'application settings'? Maybe an update reset the device settings?

Just an honest question because I haven't got around to testing/using my microphone yet: How can one tell that the microphone does or doesn't work in-game? Are you supposed to hear yourself talking?

A while back someone had mic issues. For him it was the ptt button being different in game vs origin. Check that.

How is that not what I said?

Either way @carefull I think this is your problem as well.

It worked before, and I have tried keeping it at default keybind as well. I can bind it to Ctrl, but the thing is, it's not just PPT that does not work, the microphone in the game does not pick the voice even if I have set up to "Always On". I will rebind it to the same Ctrl it has in Origins, but my feeling is it's not the bind, it's some obscure setting somewhere I messed up when I tried to fix echo. My troubles started with the last time Drivers got updated, when I lost the headset sound altogether (and yes, I turned off and unplugged backup speakers).  When I got it back, I got echo, fixed that, then the voice got lost altogether. Anyway, makes me more determined to buy a console next time I am shopping for a gaming set-up. (sigh) it sucks.

I'm aware you already said so, but your mic does work in other environments, like the windows desktop, Origin itself, Steam?
