No game audio/sound with USB device/speaker(working solution)

[Vegz78]

Some users have reported missing sound from MakeCode Arcade games when using USB audio devices.

Apart from the requirement for ALSA sound drivers for sound in MakeCode Arcade games, which might be missing(alsa normally installed, because Pulseaudio is built upon alsa), your desired audio device may not be installed as default on hw:0,0 which MCA games require.

I only have and am able to test the regular HDMI and jack audio outputs supported by default on Raspberry Pi. Thus I sadly have not been able to help with USB sound issues.

Luckily, there are always users out there who find and share their working solutions!:
