I made the test on my Apple Base Station V6.3. Just to be clear, this is an
Airport Express not an Airport Extrem as Apple provides two different products.
I use simple pipelines as :

"gst-launch [--gst-debug=apexsink:5] filesrc location=my.mp3 ! mad !
audioresample ! audioconvert ! apexsink host=my_apex_ip volume=100"

and it works very well about the given sound. As far as I know (attempting
while coding) The only reasons that might give a noise in place of a clear
sound are :
- a wrong plublic RSA key (may be you use a more recent firmware than me and
apple changed the key [that's quiet not possible])
- OpenSSL not supporting OAEP padding (RFC 2437), as far as I know, if openssl
is build with external RSA RSAref implementation, it should be patched to use
its own . I discovered this padding support issue while trying to use gcrypt
that does not implement it.
- it happened to me with some "misencoded" files,
- a wrong format, bitrate, endianess, un/signed, width or depth but the caps
should be automatically negociated...

I just uploaded new sources. Please let me know if you still experience those
mistakes. Could you tell me about your Airport Express firmware and openssl
version please ?
