I compared an Adele Skyfall flac file to the official music video on youtube and youtube's version had a much more crisp, and accentuated recording.
 
I always thought youtube videos played mp3 files?

The 720p/1080p MP4 container on youtube uses 192 kbps AAC for audio. The WebM (HTML5  version of youtube) container uses 192 kbps vorbis.
 
This doesn't guarantee high quality though because the uploader could have used a different lossy codec.

So in this case we cannot generalize that the Youtube HD sound quality is always be better than 128 KBps MP3 ?

Guess not.... I think the it mostly depends on the person uploading it.

So what is the maximum quality of Audio file in Youtube ?

Max 192kbps AAC or Vorbis

But even if a video is HD (1080p) the uploader could have used a 128 kbps MP3 file.

Absolutely.
192kbps is the maximum. So I'm guessing anything higher will be limited to this.
