You tacked onto an old thread, where audio issues mentioned may have been fixed. So a new one has been started.
What version of VP is running? Look at the opening screen or the left-bottom of the window. What is the format of the file?
Open OPTIONS | MEDIA tab and UNcheck this box... 
Then close VP and reopen without loading any files. Open OPTIONS | DISK tab and Clear Unused Cache Files.
Close VP. Now try your project again.
You can also try this version. If the problem persists, we need to see the file...
It's easy and can be private. Upload the file/s to a free server, such as Google Drive or MS OneDrive, get a shared (public) link, copy the link and paste it here or to me in a Private Message via the mail envelope in the top-right corner of this forum. When using Google Drive, if necessary change "restricted" to "anyone with link can view."
