Convert the files to wave, see if that will help.
mp3 and wma are not very well suited for editing.
Thanks. Just tried that and it didn't fix it.
I can see the Audio Meter bars moving but can't hear any sound.
Also can't hear any sound from the MXF files either. Will have to restart Premiere again to get it working.
EDIT. Left it for a bit and the MXF files now play ok in the Souce window but music files still don't.
What are your settings?
Thanks. Try again, one more down. (Audio Hardware)
Also, change 5.1 Mixdown to Front Only.
It was the Audio Hardware setting.
Once changed from, Creative ASIO (audio card) to Premiere pro WDM sound everyone started working ok.
