Prevent playing music discs with speaker.playSound

I have mixed feelings about speaker.playSound. On one hand, it's pretty
useful to be able to play any sound. On the other, it sometimes feels
... maybe a little too magic?

One particular thing I don't like is that it allows you to play
arbitrary records, which sidesteps both a vanilla mechanic (finding
record discs) and existing CC functionality (disk.playAudio). We now
prevent playing record tracks from the speaker.
