File not playing on Audio FX Mini Sound Board

by oldblackcrow on Fri Oct 09, 2020 2:33 pm

Checklist:
1. Soldered LiIon/LiPoly Backpack on to FX board. Battery charges, no issues there.
2. Soldered Mono 2.5W Class D Audio Amplifier - PAM8302 on to FX board.
3. plugged in the FX board to WIndows 10 computer. I hear a very nice distinct beep from the speaker connected to the FX board.
4. Upload 9 ogg files, named T03NEXT0.OGG - T03NEXT8. FIles sent over with no issues.
5. I plug in a LiPo battery - granted this is only a 100mAh but I'm just using it for testing.
6. I jumper ground with Pin 3. Red light comes on lasting the appropriate amount of time of the file, but no sound. I hear some static through the speaker but it is very quiet.

I changed the volume on the amp, but that does nothing.

I'm clueless... any ideas? Thanks!!

@oldblackcrow,

What quality are the OGG files? The AudioFX likes these parameters:

small, 22Khz (or lower), 16 bit PCM, mono .wav file!

Well, even using your test files (Demo Tracks), it's not playing... Again, when I plug in the board to the USB, the speaker plays a very nice distinct beep, but the files only show the red light with no sound.

@oldblackcrow,

It will not play audio when it is connected to a USB computer port (mounted as a drive). Are you powering it from a USB wall plug or the 3000mah battery only (not connected to a computer) when playing?

I assume the audio files are in the base directory (not a folder), is that correct?

That is correct... Main directory, running off battery. Just using usb to transfer the files over. Thanks!

@oldblackcrow,

A lot seems to be working (aside from the playback) so I'm guessing there is something going on here. How is the unit wired up to the play buttons? Can you please upload a photo a photo, 800x600 resolution works best of the images. I'd like to verify any wiring issues.

I have not yet wired any buttons, as stated in my OP (number 6). I am only using a jumper wire for testing purposes, as my final wiring will be rather creative. I have to run a wire through a plastic robot, which will have to be customized for proper placement.

Great photos.

Definitely go over some of those cold solder joints again. The solder will need to flow smoother between top and bottom. The ground looks the worst, but they might all need a touchup.

I resoldered all the joints but still nothing.

Last week I purchased the FX with built-in amp. Saturday, I connected it to power and the same speaker and it works perfectly.

I'm at a loss. Maybe a bad board (amp or fx board)?

@oldblackcrow,

When did you purchase the original Audio FX Mini which is not playing these files?
