I tried everything: changing to Core Audio both (and one at time) Capture and Playback, changing all kind of option like push-to-talk, voice activation, etc. TS3 has never detect any sound from my Mic (iMac built-in mic). I tried to install the last build (beta 25) today on my Imac 27 early 2010 ( OS X 10.6.4 ). Last edited by Perianah June 12th, 2010 at 03:19 PM. I have no idea what the problem really was, but I am so happy that it is working again. I reinstalled TS3 with the latest build and now it is working again. After that I deinstalled TS3 and cleaned everything up with Onyx and I also repaired the files permissions. I tried it with a different headset from my friend (Speedlink Medusa 5.1 USB) and it was the same problem.

However the internal microphone still works fine, this is only the case with the microphone of my headset.ītw, the other builds (until beta20) were working with fine with this headset the last few month, so it has to be a problem with the last two updates. This wasn't the case with former client versions. I also have to put the volume control for the voice activation nearly completely to the left to activate the microphone. Even if I turn up the mic volume to the max in the system settings and also my volume of the headset speakers, I just can hear my voice very low with a lot of hissing. I can select my USB soundcard (USB Headset Plantronics Gamescom 777 used with an iMac 27' I7) in the TS3 preferences with your solution but unfortunately my mic is so low, that nobody can hear me. I can hear all others but they can't hear me. I have the same problem since the last update but your solution doesn't help me completely.
