When I use neopixel (WS2812B, 60 LEDs) on my Rpi 4B the sound from the Raspberry Pi itself stops working (the one i get from HDMI still works, but since I usually don't have a Monitor attached, I need an alternative). I use pulseaudio, which I already tried to make systemwide, but that doesn't seem to work. My OS is Manjaro Linux for RPi.
If you have any idea how to fix this, please tell me. Thanks in advance.
