ProtoDAC + CamillaDSP can't open audio output - mszulen - 11-22-2024
Hello Folks!
I'm using ProtoDac I've built recently (switched over from Pimoroni PhatDAC) and everything works well when not using any DSP, just direct output with software volume.
When I select ProtoDac preset (or any other like "Polarity inversion with vc") in Camilla settings, I'm getting the "MPD can't open audio output" error message.
Is there something I'm missing?
Another thing - there's continuous noise in the background regardless if I'm playing something or not. It also seem to catch the bus noises from pi. Is it normal for protodac or it's just the nature of non shielded pi?
Thanks in advance for suggestions.
Thanks!
Marek

What version of moode?
Are u using the V2 Camilla configs?

Hi Tim! Thanks for getting back to me on this.
On that one (Pi 2B in my office) I use Release: 8.3.9 2024-02-23 as 9 did not work on that old PI (it did boot but going to Audio setup was giving me a "404" error and crashing).
And yes, I do use V2 configs (V2-ProtoDAC)
I have another PI (3b in the living room) with HiFi Berry Digi+ Pro running v.9 and all works ok there (including Camilla)
I just found another Pi3b in my drawer. I will test it with version 9 and ProtoDAC. I guess, it might be something related to either v8 or older Pi.
EDIT:
I've installed version 9 on a second Pi 3B with ProtoDAC - CamillaDSP works without problems... No output errors. I guess, I'll just stay with this config and utilize Pi2 for something less demanding.

Ok cool :-)
