@hon68 are you sure you set a keybinding to it? if you use push to talk hold an assigned button..
for this i tested my samson usb mic on apex, some things to check:
-mic needs to be default mic in windows audio configuration
-set the mic level to a decent audio input volume
-disable option "allow exclusive acced to audio device"
-optional set audio sample rate to 44khz/16bit
-in windows mic privacy make sure "allow access" is enabled, go down and also enable "allow desktop apps to have access"
-make sure steam/origin have acces to your mic in the options
if you are using steam you can access the mic options by using the "friends" window and hitting the gear icon in the top right. From there go to speech in this option set:
-your mic as default input device
-optional leave the setting as "open mic"
-try setting "threshold" to off for the time being
i dont have origin installed to try it out..
in apex you can also try to set it to open mic if you want, in either case make sure the mic is loud enough for apex to pick it up
