hi Ok, the bug has been filed at: https://bugs.freedesktop.org/show_bug.cgi?id=94889. This provides support for the audible audio format, but purely based on the file extension. Next is to get support for this put into gstreamer. Where should I start for that? I'm no programmer, but since the audible file is a container with other audio inside of it it shouldn't be too hard. Usually mp3, but occasionally the acelp or sony's HAC ((hearing aid compatible) codecs are used, although I don't have any idea what those last two are. Thanks Kendell Clark
