... should give us all your versions of everything. Which Windows, Which Audacity, etc. Stay from adjectives like "the latest." Do you have FFMpeg and lame installed? The only experiences I remember are exporting to AC3 and I think you need FFMpeg for that. Koz

OK,thanks for replying, I will mark it [SOLVED] then.

FFmpeg "should" be able to import M4A containing AAC, but M4A is a "container" format, so your file might have included some other format than AAC, which might trouble FFmpeg.

It always helps to know which "that"? The Extended Import Preferences or finding FFmpeg?

You still need FFmpeg to export M4A.

Try uninstalling the Debian packages of Audacity and build Audacity 2.0.3 from our source http://audacityteam.org/download/source (configure --without-ffmpeg if needed).

If that does not help, please paste the content of Help > Audio Device Info... in Audacity.

Great, compilation failure in an FFMpeg header... As it says in the manual (http://manual.audacityteam.org/o/man/faq_installation_and_plug_ins.html#linff) : FFmpeg version information: Audacity should support building against FFmpeg 0.5 through ...

... since Debian's audacity worked for me in October last year (Not sure if that's the version I was using though) Great, compilation failure in an FFMpeg header... maybe newer GCCs don't like their dodgy stuff. Will hunt for an old Debian binary... # old versions, from the stable release http://ftp.us.debian.org/debian/pool/main/a/audacity/audacity_2.0.1-1_amd64.deb ...
