Saving the RTP payload to .au format does not work anymore. It saves a file
with "null" content.

Scenario:
- Open the attached RTP_pcmu.cap file with Wireshark 1.0.3
- Go to Statistics/RTP/Stream Analysis, then "Save payload" button.
- Choose .au format and forward channel.
- Save to a .au file.

Result:
The file seems to have the right size, but playing it shows no sound at all,
but you should hear a "one two one two". Opening it with an hex editor shows it
contains only 0x8284 words.

Workaround:
Saving payload to .raw format works.
