Support for USB Audio - Activate with 'dtparam=audio=off' or Menu selection?

[Higgy69]

Hello, Can USB Audio devices be supported please. The usual method requires Root access, I understand you want this closed so could you do the 'behind the scenes' changes then have it activated either possibly by Config.txt 'dtparam=audio=off' which is editable via a PC or maybe a Menu option?

'lsusb' detects the C-Media device

Ok so the why. Well I've a bartop arcade which I am planning to upgrade from a RPi 3 and a very old Pi2SCART OS build and I have USB Audio and amplified speakers. Also for RPi400 owners who don't have an Audio jack, gives them (and all RPi owners) options. More options are always great :)

Thanks

config.txt is in the fat partition so no need for root access since you can plug the SD card in your PC and make the changes. Anyhow USB audio devices or any other audio DAC won't work properly since they normally work at a fixed rate of 48Khz and the system currently works in variable audio rates.
