The Vorbis player output is noisy, producing what sounds like static crackle and stuttering at the beginning of playback. I tried all the examples shown on this Talk page, and every one of them behaves the same way. Curiously, if I pause the playback and then resume it, the sound comes out cleanly, without the static or stutter. Is this a problem with the Vorbis player implementation, or is there a problem in the LilyPond notation conversion to .ogg format? I'm accessing the player with a Linux machine, if that means anything.

I have the same problem on Windows XP.
and on mac os x 10.10.5 also. Any news?
I downloaded the ogg file and opened it in Audacity sound editor. The problem is in the ogg file, not in the player. The crackle is only in the right channel.
I think you're noticing what I reported this in phab:T50029 "crackling at start of OGG renditions of MIDI files." The bug in the third-party TiMidity software that generates the audio file. It was fixed years ago in a newer version, TiMidity++ 2.14.0, but the Linux distribution that the Wikimedia Foundation uses doesn't ship the fixed version :-( . Instead the extension switched to using Fluidsynth to generate the audio file (phab:T181897).
What's interesting is the crackling noise is still present in the sample on Extension:Score and on some of my old user pages, but not if I copy that score tag to a new page and preview there. It seems Mediawiki aggressively caches the generated audiofile for years!? I wonder if there's a way to invalidate all the generated .ogg audio files in some cache.
