Audio issue on MAC using HDMI audio out

[knubo]

I'm trying to use the latest Sonic PI for mac (3.0.1), but it has a problem outputting audio to HDMI. It does not give any error when starting up, but the 2.9 version says:

Hi there, is there any reason you're not using v3.0.1? Could you try with that first?

[knubo]

I tried it on 3.0.1 and it fails to play the audio nicely. It just comes out as distorted noise when I do this when playing using HDMI output. It works fine when using the regular audio port.

Hi, could you try v3.1.0 to see if that has improved things?
