Audio into blog post

Does anyone have or know how to fix this - I think it is a general issue (1.6.1) where mp3/mpeg files cannot be embedded in a blog post, comment, wiki-page etc. I have zaudio, aaudio and embed all installed and active.

I would expect the embed plugin to do this but it only puts a link to the file there - it does work for pictures but not audio files. I may be able to hack the embed code for mp3 but it won't be pretty (!) and I'd rather have a proper solution if possible or if it already exists.

Adding mp3s to blog posts I am sure must be a function in great demand (for podcasting, etc) so I think it would be a worthwile development - it should be fairly simple I'd have thought. TinyMCE will be the main barrier I suspect.
