i used to use Final Cut Pro but because I hate mac I am using Premiere while i do my documentary. I have imported my clip (.mpg from a sony handycam sx-40 series model) but there is no audio track when i drop it into the timeline.
I am using CS3 and as my computer is very new i know for sure that the problem is in the program or file not the hardware.
Did you check all of the Audio and Audio Hardware (especially the ASIO) settings in PrPro?
Did you update your Realtek, or similar, audio driver?
Did you do a test with the ASIO4All ASIO driver?
It might be best to post to the PrPro CS4 & Before forum, as others will likely see the post, and can offer more input for you. No one, but me, will likely see the post here.
