Via Stuff about code.
I recently made myself a Pocket PiGRRL based on Adafruit’s tutorial – it really is a great machine and a brilliant learning experience.
There was one aspect though that I didn’t like, the speaker hisses, not particularly loud and when your playing a game its not that noticeable but if you have got the volume down it is really annoying. Its all down the Raspberry Pi’s noisy analogue audio out so there isn’t a great deal you can do to clean it up.
My solution was to add the ability to shutdown the amp, effectively muting it when I didn’t want any sound.
