Hi -
I’m having some trouble getting Ardour to run on my Raspberry Pi 4 B. I hope somebody can offer some help.
I’m running Ubuntu 24 LTS, mainly because it’s got a realtime kernel available standard (well, you need a pro account, but they’re free).
Cyrus Adkisson reported success with this model five years ago:
The biggest difference I see between my setup and Cyrus’s is that I’m using the Pi’s onboard audio (“bcm2835 Headphones”) instead of a hifiberry.
A hifiberry sounds like a very good idea, but since the onboard audio playback sounds OK when I’m using mpg321 to play an mp3, I figure Ardour should work too.
Unfortunately, Ardour’s sound quality is terrible. I’ve tried both ACE Reasonable Synth and importing an mp3 with the same results. Sound is very “choppy”; a bit like lots of xruns, but there are no xruns (or very few). ALSA or jack both act the same way. Nothing in the messages window to suggest what might be the problem. The stock ardour from the repository and one compiled from the github tree both act the same way.
Any ideas what the problem might be?
My hope for this project is to mount the Raspberry Pi inside a Williams Allegro 1 keyboard that I picked up used and replace the keyboard’s sound engine with Ardour, to get a keyboard that runs Linux.
Thanks in advance for any feedback anybody can offer.
