Yes, dozens.

As well as 8 and 16 bit integer PCM files, there are also 24 
and 32 bit integer PCM, 32 and 64 bit floating point PCM,
A-law, u-law, at least 6 different forms of ADPCM (adaptive
differential PCM), GSM6.10, MP3 and many, many more.

Fortunately other than the ones listed above, all the others
are pretty rare.
