Old files play, New files don't
I recently built a new machine with a new install of windows and some updated hardware. I didn't change my sound card, which is an RME Hammerfall DSP 9652. My old files open and play just fine, but new files give me an error message:
"Unable to open audio playback device. Device may not support the current project's audio format or may be in use. For help, please visit..."
I have the drivers set to ASIO, in case anyone's wondering, and like I said, old sessions that were created on my previous machine work perfectly. It just doesn't like the new stuff.
My motherboard's built-in audio is set as the default playback device.
Any ideas?
Thank you in advance.
