seek bar issues when playing m4a

Bug Description

Steps to reproduce:
1. Play A State of Trance podcast m4a file. Notice that seek bar indicates that we are a few minutes into the song but it's actually playing the beginning.
2. Try to seek halfway through the song. Audio that starts playing is from halfway through the song but the seek bar jumps further in the song.
3. Press pause. Rhythmbox pauses.
4. Press play. Rhythmbox doesn't play.

Even though the song I'm playing is from a podcast it's not specific to the podcast area of rhythmbox. I can reproduce the issue when copying the file to my normal library. See attached screenshot.

It does seem to be related to specific types of m4a files, though. I have others that don't reproduce the issue.

I don't think it's a duplicate because that bug is about a file that's not fully downloaded.

Attached is a screen cap of the seek bar right after I start playing the file, it should be at 00:01 or so.

I'll also add that Totem plays this file without issue, Play & Pause work as does the seek bar.
