Bug Description
Binary package hint: gstreamer0.
Steps to reproduce:
1. Ensure you have the AAC encoder and decoder plugins (sudo apt-get install gstreamer0.
2. Insert non-drm-protected audio CD
3. Start Sound Juicer
4. From Edit | Preferences, select Output format CD Quality, AAC (MPEG 4 audio)
5. Import the CD
6. Play the songs in any Gstreamer-based player (Totem, Rhythmbox, Exaile!, ...)
Erroneous outcome:
Playback is ugly (constant jitters, noise, distorted or unrecognizable audio)
Expected outcome:
Playback is fine
Discussion:
Songs imported from audio CDs using the default AAC seetings (Gstreamer pipeline: audio/x-
The same audio files, uploaded onto an iPod, play back very fine, although reported track duration is incorrect (for example, 15'+ reported for a circa 4' song). Still the same audio files, when played inside the latest iTunes on Windows, also play back fine and report the correct track duration.
Please, also note that other audio files, previously imported from audio CDs though the latest iTunes on Windows using the same hardware, play back just fine in all Gstreamer-based players that can't play back the files encoded through the Gstreamer AAC encoder. I think this might point to a problem in the encoder rather than the decoder, but feel free to ignore this as uninformed guess at best.
I can attach or post a sample encoded track, which I think I could do under fair use. Please let me know if this is acceptable and if this could be helpful.

Same here. Files encoding using Banshee in aac (gstreamer-0.10) won't play. On the other hand, banshee plays m4a files encoded on other platforms.
