Hello everyone.

I am very close to the end of my first build, so far so good. The only thing that i am missing is audio.
I am having big troubles setting up my usb sound card. I followed a guide here on the forum and everything seems to work fine (audio comes out).

USB sound card

The issues start when i reboot the system. My sound card (wired to the usb hub) doesn't work anymore. It isn't recognised by the system, and its power led is completely turned off. If i plug in and out the sound card it starts working again.
I tested the wiring and it is all good (works like a charm with a usb external drive).

A guy in this post might have my same problem, but i can't figure out how to solve:

Thanks for your help and patience, i hope i will find a solution to this

Did you make your asound.conf file and set the default device to your USB audio?

Of course I did, as stated in the guide. The issue is that the card is not recognised when the system boots, but I have to plug in and out

Found the source of the problem.

I flashed a new sd card with a fresh installation of retropie. While making all sort of settings needed to run, i noticed that the usb sound card stopped working at boot AFTER activating the keyboard function for the buttons:

The brick happens after i edit the file putting this code: Any ideas?

So, when I was messing around with my USB sound card I would noice that whenever a wire became disconnected, even if I reconnected it, the sound card wouldn't work until I unplugged it and plugged it back in. A signal break so to speak. Never problems on boot though... But I was using a USB hub and a teensey. I wonder if something is happening when the retrogame hits the gpio for the controller that cuts the USB signal or something similar, even briefly, causing the sound card to need to be re inserted. Just stabbing in the dark here.

I use the same card with GPIO control wiring and don't have these issues.

Any pics of internal wiring?
