Failed to start server: Unable to boot sound synthesis engine: the input and output rates of your audio card are not the same. Got in: 16000.0, out: 44100.0.
You'll need to open "audio midi setup" to make those sample rates match. Sorry for the short answer but I'm replying from a phone.
Hope that helps,
Xavier

Yes, apologies - unfortunately this is a limitation of the underlying synthesis engine - the rate of your in and out sound card settings needs to be identical.

If you have a bluetooth or USB mic attached (perhaps in a headset) try removing that and restarting Sonic Pi.

It would be great if sonic pi could just ignore a non-supported device. It is annoying to detach my voip headset just to run the problem-- I don't intend to use that headset with sonic-pi, but it's still attached to my machine when I am plugged in to my thunderbolt display. Can this just be made into a warning or grey out that particular device?

@programmerq

we’re aware of the issue, but unfortunately this is not trivial to implement. It requires changes to the underlying synthesis engine which we’ve been discussing with their development team. As soon as we are able to technically achieve this and also assuming we have the capacity (we have very little funding which is rapidly running out) then I’d be very happy to add this feature.

If you (or someone else) is interested in helping implement this - that would be wonderful. Alternatively, you might be interested in supporting the project over on Patreon: http://patreon.com/samaaron
