Hi MattS
Thanks for your post.
Can you give me some more details?
Are you receiving an error or will it just not play in the mixing screen or media browser?
Will the application open up okay?
What version number are you using?
Have you changed your sound card or another piece hardware?
If you have changed your soundcard set-up.
Go to Options in the main toolbar and select mixer configuration: (see screenshot)
and then in the dropdown box select the sound card you are using for playback.( see screenshot)
Then click ok:
You may need to open a new mixing window to see this change.
I look forward to hearing from you
best regards
Cormac
