URGENT! Pro tools HD9.3 playback Probelm
I need your help urgently.
I have a Pro tools HD3 setup on a dual core Mac Pro OS-X snow leopard, using pro tools version 9.3 in my studio, but I am having serious problems with the playback of audio files.
I can record and everything runs perfect, but when I try to replay the recorded audio all tracks just play out a REALLY loud "KRRRRRRRR" (distorted digital noise, all meters in red!) noise on all outputs.
I have tried to delete preferences, database and set-up files, restarted the computer and pro tools. This procedure helped once or twice, but the problem returned after just a few hours.
Now I have reinstalled the whole system on a clean new disc and it worked for 7 hours straight but just now the problem returned. I can't playback any audio files from pro tools, but I can record as much as I like. If I burn the audio files on a cd, they play as they should, but as soon at I press play on pro tools all meters just hits the top with unpleasant noise!
Can anyone help locate the problem?
I am desperate!
