Audio devices not found.

o0Mr Robot0o

I recently was gifted a GP430 from a friend and after upgrading the compute module to a 3b+ I had laying around and ps vita analogs I had in my parts bin. I tried digging online for a stock image to flash on it I had zero luck finding anything for this thing so I decided to flash the latest Retropie image and was successful getting everything booted up and my personal rom sets transferred onto it and even managed to tweak the config file to make it work on this thing but I'm having one issue...no audio. I've looked in the raspi config, emulation station etc and I get the same error... audio device not found or disabled. I'm wondering if this is something I can fix by a finding a driver for this thing or something else I did wrong setting it up . Any tips or help is greatly appreciated.

This means exactly that - the on-board audio devices are not detected. Did you disable the audio by editing /boot/config.txt ?

o0Mr Robot0o

@mitu no sir. I literally copy pasted the config file that was on the image this thing shipped with only modifying the resolution. The card my friend gave me booted into emulation station but nothing worked so I just flashed retropie and copied the config file from the boot partition in the old memory card into the new install. Everything has been smooth sailing except audio device not being detected.

This are not mutually exclusive. You've copied the configuration file (/boot/config.txt), which might have disabled the on-board audio. Post the configuration file's contents and also the output of the aplay -l command.

@mitu Yessir. This is the contents of the config.txt file:

This lines above show that on-board audio is disabled, hence the message you get when trying to configure it. How does the device outputs audio from the Pi ? Headphone Jack/HDMI/GPIO (less likely since it looks like it's used for display)/USB ?

o0Mr Robot0o

@mitu The device has an onboard speaker, 3.5 headphone jack and hdmi out as well that can be used. I was trying to get the onboard speaker to work.

mitu

@o0mr-robot0o Yes, but how is the speaker connected to the Pi ?

o0Mr Robot0o

@mitu it's soldered to a custom pcb that holds the compute module etc. Should I edit that line to "yes"?

If you replaced the CM with the 3b+ board, I wouldn't expect this to still work.

Sure, why not, but I don't see how it would work if you don't connect any of the audio outputs from the 3b+ to your device's speakers.
