Work is going on to try and improve the sound selection, but things are still changing in the pulseaudio setup (for example not all outputs seem to support stereo at present, and the 3.5mm jack output can’t be used when HDMI2 is active. In either case, if you are using an external jackd dont forget to kill it when you finish, or you wont be able to use that card with pulseaudio (until you reboot). You can then use this to configure and start jackd before starting Sonic Pi. It is probably best not to select the same card with the new audio selector on the menu bar in that case.įor greater flexibility in specifying different sample rates or connecting audio inputs to SP you may wnat to enable QjackCtl in the Main Menu editor (in Preferences on the Pi Main Menu ). This will not be the cause at present if you select another sound card using jackd. The OS does I think let you use this even if there is a pulseaudio proram using it too. asoundrc so it doesn’t work for sound card selection. The foundation supplied Sonic Pi 3.1 (still in the new OS) didn’t have sound card selection implemented, and so also uses HDMI sound. asoundrc file to check which sound card to use, and if it doesn’t find one it defaults to connecting to sound card 0 which is usually HDMI so if you don’t have speakers in your monitor you wont hear anything. To clarify your thoughts Sonic Pi is designed to check for a running jackd when it starts, and if so to make use of that. Be nice if I could tweak some SPi code to run it for me. So if this is robust workaround, I’ve no problem with it. Then let there be sound! (Fiat Sonus?) OK, I use a USB soundcard on my Windows machines to avoid all the typical onboard sound/driver problems. I’m guessing but it seems that SPi starts it’s own Jack server on startup? So this one gets in first (sorry for the technical language) jackd -d alsa -device hw:Device & Then run this to start Jack with the USB card.

But a little trial and error got a workaround, using a USB soundcard.įirst, switch to the USB Sound Card from the GUI top bar, as usual. Reading around, all sounds a bit complicated and I don’t understand it, yet. The Dec 2020 update to the Raspberry Pi OS now uses pulseaudio and it broke my setup.
