Can't seek when playing MPEG layer 2 and layer 3 audio files

[Alex Jones]

Totem can't seek at all when playing MPEG Layer 2 or MPEG Layer 3 audio files. Strangely, layer 1 files seek properly, as do some layer 3 files. The attachment is a collection of sample files in all three formats, plus the lossless original. The audio I used is from the CELT codec test site. The layer 3 file in this archive plays properly, but some other layer 3 files don't. If I find one that doesn't work that can be distributed freely I'll upload it.
