Audio Stopped Working During Halloween Show

[griswold]

I began to hear static and cutting out then no sound. I ended up using a different audio device than the on board audio hat on my fpp raspberry pi 4. I thought it might be my HAT (raspaudio hat ultra++) so I bought a InnoMaker HiFi DAC HAT RCA (https://www.amazon.com/dp/B07D13QWV9). I still don't have sound. I changed the sound settings via the /boot/firmware/config.txt to dtoverlay=allo-boss-dac-pcm512x-audio then after a reboot no luck so I tried dtoverlay=hifiberry-dacplus and no luck. I had it set to DSP Program for both the latters. Please help

Also, just realized that my lights are not blinking either but the F16V3 shows data, i.e. e131 packets

The on-board audios on the Pi's have a lot to be desired.
I dont know anything about the Infomaker you got But I can tell you I have a number of Soundblasters and they work every time.
