RGB20SX no left Channel Audio - Possible Hardware issue, but with a software / audio driver fix? #1062

No left channel audio on RGB20SX.

Suspect this is a hardware issue with the internal speaker setup as it works fine through HDMI, but not with wired headphones / internal speaker.

Tested and confirmed on ARKOS and JELOS .

Can be reproduced with 240PEE test suite on GB / GBA etc

Can get round it by using DSP plugin mono in retroarch.

Could also be 'fixed' with the option to run the OS sound drivers in mono mode (Maybe a switch / tool to switch between stereo output and mono output in options / advanced etc)

I'm not supporting the rgb20sx unit. You can try replacing the /home/ark/.asoundrc file with the one here and see if that resolves your issue. Other than that, I have no other suggestions.
