The problem with many embedded audio systems, this especially includes
laptops, is that their power source is typically too close to the audio
chips and results in a lot of noise.  In a laptop you can hear this by doing
some experiments of running on power vs on battery.  In something as small
as a plug computer I would imagine that this would be a problem.  The way
around this is to use a usb audio interface.  So if you're not happy with
the on-board sound quality have a look at something like this.

about $30.
