I tried many answers on different websites. Raspberrypi.org, this site, linux.com, and others I cannot list. I tried Analogue with
sudo raspi-config. I also tried
amixer cset numid=3 1. I tried updating and upgrading. But nothing is working. I tried the hello.bin wave sound, that worked. But nothing else is working. I verified the speakers work on a Windows PC and macOS X Mojave. But they don't work on Raspbian. Do I need to re-install the OS? If so how can I back up the configs without losing everything again?
Your help is appreciated. I'm not very experienced with my Pi, so please be patient with me, as I am autistic.
EDIT: The hello thing does work. But no other videos or .wav files are working. I would set the volume to max, and then right-click the icon and click 'Analogue'. But then the sound resets to mute every time.
EDIT 2: VLC Media Player
EDIT 3: I just edited the file and saved it. I rebooted and tried the audio, but it still resets to mute every time I turn the volume>0
