Sonic pi not working with external speaker #1983

Open ostephagus opened 6 years ago

ostephagus commented 6 years ago

I am running sonic pi version 3.1 It works fine but when I connect the speaker via aux cable it does not play. The speaker works fine and so I am wondering whether it is something within sonic pi. I am new to ruby and sonic pi Thanks!

The same problem with MacOs X and Airpods connected

Hi hectorinx If you look at the server output log you can see the cause of the problem. There is a disaparity between the input and output audio rates. Sonic Pi (or rather the Super Collider scsynth it uses) require the rates to be the same. This solution https://github.com/samaaron/sonic-pi/issues/1512 might work in your case.

I found a workaround, documented in #1471, included here.

I found a workaround for using Apple Airpods on a Mac laptop with SonicPi at full 48khz without using Audio Midi Setup.app. This may work for other Bluetooth headphones!

If you set the Output audio to Airpods, and the audio Input to the internal speaker, Sonic Pi will boot just fine.

Hope this helps someone else!

@garrow this worked for me, thanks!

@garrow How do you set the output audio to a bluetooth speaker? (I am using a Linux Raspberry Pi.)
