I was wondering if it was possible to play audio from a website, such as a youtube video. Couldn't find anything online about it. I wish to connect the Arduino via ethernet and play sound from a website onto the connected speakers. Is this possible? How would I go about this? I am quite uneducated about the topic and any advice is appreciated, thank you!
Audio comes in many different formats and filetypes. Some are compressed files, some compressed streams. You may be able to deal with a couple depending on what kind of decoding hardware you can hook up to your machine.
For example this boardplugs into an Arduino and can play mp3 and WAV files.
Other than that, I think it would be really tough.

As a rule of thumb: Arduinos can NOT play video or audio files.
On the other hand, Arduinos can control another device that plays those files.
It sounds like what you're trying to do is streaming audio/video from the Internet, playing it on a local sound system. That's something you can get the RPi to do in a heartbeat. No chance with an Arduino.
