Title: Mini Amp Turning Itself Off/On endless loop
Post by: ssdesigner on April 29, 2022, 03:55:01 pm

I have a small rasp pi 4 bartop arcade with iPac 2 controls. I run audio from hdmi to my PC monitor and the audio out from monitor (3.5 mm headphone) to a RCA splitter into a small audio amp. Bose speakers are for cars and they are connected from the mini amp via speaker wire. I had this happen before and I can't remember how I got it to stop. I rebooted my Pi and the little Kinter MA170 mini amp is now in this on/off skipping loop that won't stop. It's a small audio pop noise that repeats endlessly.

I've unplugged everything and let it sit overnight already. Plugged it back in and it starts up. The LED on the amp flashes in unison with the small audio pop noise. Any ideas?

Thanks Shawn. I went ahead and ordered a new mini amp yesterday since they are cheap. I'll report back once I get it hooked up and test it. If the amp is bad, I'll be installing slide rails to hold the amp in place instead of screwing it down to the inside of the cab. If I'm going to be replacing these every year or two I want them easily removable :)
