I got the following error.
Audio Device is Currentry Unavailable
Another program (maybe another copy of RV?) is blocking use of the audio
device. If you quit the other program you may be able to use the audio again
if you restart RV.
You might also try other audio device in the preference audio tab.
I launched only RV., never used other programs.
However this message appeared.
Please let me know how to activate audio.
Thank you for your help!
