No playback audio
I am on a mac Intel 10.4.8 using Protools M-Powered 7,1. Everything seems to be working fine - exept for audio playback through head phones. I can record, set new tracks, but no signal through the phones. Getting strong reading through mic, but again, no audio. The mac interface appears to be different from the PC version - it does not give me the option to tuen on a or b selections for headset?
Any help would be much appreciated.
