System volume staying at 0%

[6PATHS]

I used wermy's pre-made image for the mintypi, followed the guide to a t and everything works except the audio
In the start menu I turned the system volume up in sou nd settings but as soon as I exit the menu, the setting isnt saved. It goes right back to 0%
When I tried the audio settings in retropie setup menu, i get 2 errors. One says failed to open AudioManager - failed to open ALSA or SDL audio
The other error says failed to attach default card

Whenever I try to play a GBA game, it crashes and gives me the same errors. Other roms are fine.
Anyone have this issue? Guidance is appreciated.

This likely means the USB sound card isn't wired correctly. I'd check your soldering to make sure you have the wires in the correct order, make sure you didn't lift any pads on the sound card, and make sure you didn't accidentally bridge the D- pad on the bottom of the pi with the USB port leg hole right next to it (happens a lot).

Moving this to the mintyPi forum.

One more thing to note: your GBA roms crashing is probably because you don't have the bios file. Google "gba_bios.bin".

Okay, i will double check the soldering on the sound card. I never had to put the bios file on my pi3 build with kite' s board but I'll do that if re soldering the sound card fixes the audio problem but the gba roms still crash. Thanks

From experience with GBZs as Wermy says this is most likely an issue with USB Soundcard not being attached. This is particularly reminiscent of switching between PWM and USB audio.

Check the soundcard is there from terminal by entering: $ lsusb

This should return the soundcard in the list - if not, check your wiring.

Also when you set the volume to 100% hold Select and the B button to exit the menu so it properly saves the values.

Okay, thanks for the responses guys. It was indeed the sound card like suggested. One off the pads popped off on the spot where the crystal was soldered. Luckily I had a few spares. Replaced and works now. Thanks again mates.

I too am having this issue (with my Gameboy Zero). Could wiring still be the issue even if my usb sound card is being recognized by the rpi0?

I was able to change the priority but whenever I have snd_usb_audio as priority 1, the System Volume is stuck at 0%.

My controls and external USB port work fine so I don't think its the USB port leg being bridged with my build.

I ran into the same problem and it drove me absolutely nuts! I reflashed my SD cards and modified the usb audio priorities and nothing resolved the issue except for resoldering my DAT + and DAT - connections on the Pi. Once I resoldered the DAT + and DAT - wires the volume was displaying 95%. I would recommend that you resolder those connections and post photos if you still have problems.

Thank you!! I will give that a try when i get home and see if that fixes it!
