Had sound now nothing

[millsusaf]

I have been working on this arcade cabinet/retropie setup for a while. I was finishing up everything tonight, getting the last few things setup and installed, had audio and now don't.

Worst is I'm not sure what I did. I'm running a Hifiberry Amp 2 and I've confirmed it is still enabled in the config.txt file. The last thing I remember doing change wise was connect a Bluetooth keyboard, pressed some random buttons to make sure it was working and then the next time I tried a game no sound. I've searched and searched but can not find anything on here, the wiki or Google. I've tried increasing the volume from the Sound setting in Retropie but that didn't make any difference.

Any help you can provide would be awesome. Soooo close, yet so far away....

Thanks

Since no one chimed in I blew away my setup and started over moving step by step to identify where the audio broke.

The power button configuration was the culprit. The script worked for the power button perfectly powering on and off the Pi but killed audio from the Mifiberry AMP 2. Upon further researching the reason behind the issue was that the Mifiberry AMP 2 uses several GPIO pins to communicate between itself and the Pi3. Of course one of which is the same pin the power button configuration script uses.

I have since tried to modify the script to use a different GPIO pin (GPIO 5, pin 19). The script works to power off the Pi but not on. Further research told me that the script doesn't power on just off and that I can solder in a header or use pins 5/6 (GPIO3/GND) to power on the Pi. Given the Mifiberry, it looks like my only option is to use the header which is doable but I'd prefer to have only one power button that performs both power on and off functions.

Is there a way I can meet my goal via script, resistors, etc given what I have to work with, a long button press for off maybe? I thought about wiring the button to both the reset header pins as well as off function pins (19/20) but don't believe the Pi will know what to do with that input.

Any ideas? Thanks

Here is the link to script I ran from. Here.
