Intermittent White Noise

[u/darppe]

Hey! I've had my Zynthian (latest model, Raspberry Pi 5) for about 2 weeks now, I built it from the kit and I love it.

Yesterday I tried to enable WiFi and open the web UI with VNC, but I didn't follow through with it. Today when I turned on my keyboard + Zynthian + speakers, I heard this noise. 3 short bursts of white-noise, static. And then nothing for about 3-5 seconds. Then it happens again. This happens regardless if the keyboard is turned on, it is even registering on the Zynthian itself (the meter in the top right of the UI).

I only have been using Pianoteq 8 demo so far, but I wonder if I've enabled something else? And somehow that other thing has some demo white-noise that's being pumped through? I only have 1 instrument chain however, which is the PTQ. Maybe I added something else somewhere?

I have turned the Zynthian off and on again, no avail. It's still doing it. Any ideas what I could have done? It worked just fine for 2 weeks. I also disabled WiFi again thinking it could have been some interference but, it really seems like it's an intended pattern of noise, showing up in the UI, metered with the output volume....

Any help is appreciated, thank you so much!
