I'm not sure icons with letters should be used (L, R, PTT, etc) as they won't be translated if the user selects a non-English language,

I also am not sure how to depict those actions. I thought that L and R would be ok because most headphone makers also label it as such. In addition to that I added the sound direction. Would arrows be better or (double) chevrons? What about center, should it be left and right arrows?

Is a microphone with a number better suited for PTT?

I think probably just the sound wave icons, (((, ))), ((( ))), are fine for L, R, and C
You could do waves and an arrow ((( <- but I'm not sure if it'd be better or not.

Mic icon by itself (no number) is probably fine for the PTT icons. The number is presumably always in the text right under the icon.
