Some music videos on YouTube are available in more than one resolution.
Do they all have the same audio quality? Or do the videos with larger resolution have better audio?

I'm sure the sound quality might have to do a lot with flash player as well, but I'm no expert on that.
BalthaZar comment seems to be true until 2013 from what this article says : http://www.h3xed.com/web-and-internet/youtube-audio-quality-bitrate-240p-360p-480p-720p-1080p
Since then Youtube seems to be using a constant audio quality for 360p and higher. Lower than 360p isn't commented.
Fast answer: So higher than 360p isn't needed for listening to music.
Here's a detailed list for audio qualities for different video qualities (as Dan commented, this was true until 2013):
