I just had my new $60+ Turtle Beach Santa Cruz card installed by my local PC gurus $$$.
But, I'm still having the same problem with Premiere. So, the Sound Blaster Live Card was OK after all.
I can only capture AVI files that have a maximum setting of (44100 Hz 8-bit stereo sound). Any higher configuration results in a blank audio track when imported into Premiere Pro 1.5. (I'm capturing from analog 8mm camcorder. Does the camcorder capture put a limit on the sound?)
THIS MAY SOUND STRANGE: I have noticed that before I do a capture...I must check the way my sound card is configured (via the Turtle Beach Control Panel)as well as (Control Panel/Sound and Audio Properties in XP). For some unknown reason (unless I have a ghost in this machine)the check marks change...and the recording device defaults to 'microphone' rather than 'line in'. The apply button is greyed out in the Control Panel for Sound/Audio.
