Thank you for the clear description.

Can you provide a closeup shot of the breadboard with the AudioFX so I can see the wiring and soldering.

I take it when you use the headphones you have the same experience of low volume WAV and louder OGG file?

Thanks for the reply.

You are correct. The headphones produce the same issue.

Here are the pictures. Please tell me if they are lacking in what you need to see.

Thank you for the quality photos. The board soldering looks good. Also the wiring looks reasonable. The breadboard is a little melted in some areas so it might make sense to use another board the other end of this breadboard in case that has compromised the connections.

Are all the GND pin being tied together?

Can you show how you connected the 1/8" plug to the R/L/G pins?

Do you get the same low volume on WAV playback when powering from a 5v/2A microUSB port?

I connected it to the other end of the breadboard now.

What do you mean are all the GND pins tired together?

The GND wire on from the speaker jack isn't soldered yet but it doesn't seem to make a difference anyway.

The blue brick battery I use is 12.6v, 1-2A.
I also tried a microUSB attached to an iPhone wall charger.
I also tried a Google Home power cable.

That is all the different charging options I have on me.

Would a replacement device be acceptable at this point?

Sure, Lets try a replacement since the volume works well on OGG and not on WAV. I'm not convinced that will resolve it, but it will be another good data point.

Please send an e-mail to [email protected] requesting a replacement. They will need a link to this forum thread which is your approval and the invoice #.

Hi Mikey,

I received my replacement device and that did the trick! wav files play fine now. I guess there was something wrong with the original unit.

Glad the replacement did it.

Thank you for putting up with the troubleshooting attempts.

Would you be willing to post a photos of the two boards side by side top and bottom? Maybe there is something we can learn from (component, factory soldering or PCB marking wise).

Sure Mikey. I should mention though that adafruit sent me the slightly different version of the board with the aux-in adapter so I don't know if this still helps. Here you go

Okay, so I take it you just used the 1/8" jack for your audio instead of your own wired up version you had been doing with the original Audio FX mini?

Very interesting. I didn't think to test out my original set up until you just mentioned it.

I just tested it out and yes I have the same issue on the new device when done via my original setup. If audio jack connected via the L/R pins, ogg files play but wav's do not.

That is a helpful datapoint.

It also makes me a little suspicious of your custom audio jack.

I realize that WAV plays fine through it, but maybe there is something off about the wiring or soldering?
