Improve Raspberry Pi 3 Audio Output
I picked up a Raspberry Pi 3 to replace an old laptop that we were using for playing some background music in our office. I found the audio to have a pretty bad static or fuzzz as they call it while I was doing some research. I found that enabling the following helped the high end of the audio tremendously. I believe that it may be software related but I will need to do some more research.
For now, the fix is editing the config.txt file found at /boot/config.txt of your Raspbian installation. To edit it, type the following from a terminal window or by using SSH to connect to your Raspberry Pi 3.
sudo nano /boot/config.txt
Then add the following line at the bottom of the config.txt file.
Reboot and you will find that your audio is cleaner at the mid and high levels. There is still just a bit between songs but very mild.
