I’ve had this ever since I got a new laptop, which has Windows 7. (the laptop is HP Pavilion dv7 3015eo)
Every once in a while, audio won’t start. So I shut Renoise down and run it again until it doesn’t display the error message. Sometimes it’s the first try, sometimes the error doesn’t show up at all, sometimes it’s the fifth or the fourth try but it does start with not too many tries, but it’d still be nice to get it running without all this messing around.
Here’s the log:

If there’s any other info I can offer that might help tell me 
EDIT: Oh yeah, I had this same problem with the unregistered 2.1 demo and now with the 2.5.0 b9.
