Make the Sound Good when using PulseAudio in Linux
Linux uses PulseAudio, which has a poor default configuration, resulting in bad sound.
With some tinkering with the PulseAudio file, reading a lot of websites about the settings, I was able to get PulseAudio to have sound that’s subjectively as good as BSD, Mac, etc. By default, PulseAudio uses a resampler called “speex-float-1” which is horrendous. The reason this is chosen is to maintain compatibility on very small and bad sound cards. This shall be reconfigured to either “speex-float-10” or “soxr-vhq” for best quality. Some other changes also improve the sound.

Linux users: How to Run Netflix in Kodi (original title: How to Run Netflix on the Raspberry Pi)
This is a case where a blog post is kind of mis-titled, and suggests that the article has more narrow application than it really does. The original title suggests it only applies to Raspberry Pi users, but if you actually read the article you find that the method shown should be equally applicable to any Linux-based distribution running Kodi, or at least to those Linux distros that are based on Debian (Debian, Raspbian, Ubuntu, Linux Mint, Elementary OS, Zorin OS, and many more). The same method would probably work on non-Debian-based distros as well, if you can get the required dependencies using their package managers, and if Kodi will run on them. I understand that it was published in a blog intended for Raspberry Pi users, so that’s probably why they tried to make it seem only relevant to the Raspberry Pi, but if you are running Kodi on some other Linux distro and want to view your Netflix content, you might try giving the method shown in this article a try:
