GroovyArcade / GroovyMAME Audio Issue Documentation

Summary

After replacing the USB audio device in a GroovyArcade system, several games running on GroovyMAME stopped producing audio, while others continued working normally.

The issue initially appeared to be related to:

ALSA
SDL audio backend
GroovyMAME timing

Configure AB13X USB Audio on Linux

This is a personal config for my groovy arcade install.

Include setup for stereo and mono output.

1. Plug in device and confirm detection

Check kernel messages:

devices {
  device {
    vendor "LENOVO"
    product "DE_Series"
    product_blacklist "Universal Xport"
    path_grouping_policy "group_by_prio"
    path_checker "rdac"
    features "2 pg_init_retries 50"
 hardware_handler "1 rdac"

you need a working gpg key, this is to encrypt the gmail.token file

set you gpg key id in the line 47

ENCRYPTION_PIPE = ['gpg', '--encrypt', '--recipient', 'YOUKEYHERE']

Note: Example how to get you key
