DirtyBeagles Build/Progress GBZ (Completed)

[dirtybeagles]

Does anyone have basic sound connected? I know other people have been talking about using the peto and headphone jack, but I just want to connect the speaker.

Anyone around who could help me on what I need to connect it to? If you look at my diagram I just have the speakers connected to an amplifier and power/gnd going to the breakout board.

If anyone could help me with A+ and A- connections for the amp I purchased? http://www.sudomod.com/forum/viewtopic.php?f=12&t=363

I think you need a USB audio card. There is no audio outputs on the pi besides HDMI.

But there is PWM Audio.

Did you do any of the software setup or make the mixer card?

THE PWM audio does take a low-filter setup to have it work. However, like DB and Fleder said, it is available option instead of the USB auido or HDMI.

RPi0 PWM Audio

Sorry, by mixer I meant filter. I haven't seen any reference to any audio connections besides power to the amplifier in the previous posts.

Yeah, your options for audio are 1) HDMI (not really what you want in a handheld) 2) USB Audio and 3) Low-pass filter utilizing PWM audio. If you are wanting to use option 3, go check out 1461748123 post. He has a good system working right now. Low-pass Filter

@DirtyBeagles sorry for hijacking your forum. Back to your question, I was looking at your diagram and am a little confused about how you're hoping to accomplish getting audio. You have power to amp, but no audio source. Are you going to use USB audio or PWM?

I don't think he understood how PWM audio worked

Progress 5-30-2016 (Happy Memorial Day!):

Thanks for all the responses. I figured out what the connection should be and I will be making a complete diagram probably today after I sleep I used the USB sound board.

The only issue I have is when I plug in my headphones... I still get sound through the speaker. Here is my connection and I assume it has something to do with my ground wires circled:

Here is the insides so far:

Here is a video (sorry for my lack of tetris skills): https://goo.gl/photos/3fvT6fqh1mYAumEHA

On a side note: I did notice that once my 2000 mAh battery started to get low, it started effecting the screen color saturation. When I plug it up to a 5v source like usb the screen went back to normal. I thought that was interesting and would be curious if anyone else had this problem.
