Not yet, but the firmware has the ability to play WAV files. It might "sing" something from the factory tests.

So there should be an audio processor, right? Not just a speaker with just beeps like in pc motherboards.

Hi,

It means there is code for playing .wav sound and for AK4646 in 50D 1.0.8.
and grep can be very useful (if you're lucky).

Oh, that's nice.
Do you know where a mic jack can be soldered on the motherboard and where the audio chip is?

I've just disassembled my 50D to look for odd connectors but i couldn't understand anything.
There is a strange wire going into a glued white plastic stuff on the motherboard. The wire isn't soldered and doesn't plug in.
It's in the disassembling video posted on page 6, does anybody know what that is? It goes straight towards the internal flash zone, don't know what it is but my 20D didn't have it. It would be nice to know where the internal mic is on a 7D or 60D and what kind of wiring there is (plug, soldering, etc) .

It's an optical fiber cable...it takes led light from the white plastic device. i'll try to search for the 50d service manual..i have it for the 40d but it isn't the same...

50d 1.07 firmware
 
http://www.megaupload.com/?d=BQ1YPEO0

I posted it because it is not still available from canon and is necessary to make the mod.

Where is possible to download the Alex autoexec? But Alex can try to put the 50d in rec and after make a call with a cell phone and put it near the 50d...if you can ear some noise in the audio maybe there is a connector for the mic or audio in...
