Aren't there quite a few high quality sound cards for the Raspberry Pi out there that connect through GPIO pins as opposed to USB? Wouldn't that work even better?
i haven't pursued that for a couple of reasons:
1) I usually use the GPIO for a 24bit VGA adapter that hooks up to an old RGB monitor for arcade games
2) I'm not sure how well such a solution would work with Lakka (or if it would work at all)
3) Those solutions are a good deal more expensive than my $5 usb adapter from amazon.
4) They sound better, but the $5 one actually sounds pretty good.
however, it's an interesting idea that i may look into in the future. i have one setup that goes from the HDMI to a VGA adapter and out to a monitor, but there is a whole different set of problems with that setup. (mostly that lakka is incompatible with HDMI-VGA adapters)
1) Your VGA output will work with a DAC as long as there's no conflicting pin assignments. Lots of DACs can be fitted with a pass through I/O header.
2) DAC parameters are configured from the boot partition. Including the appropriate overlay files and adding the appropriate options to config.txt will get you up and running regardless of the distro you're on.
3) They are. I'd really like to see an inexpensive DAC that just does CD quality output.
4) I agree.
