Duo 2300 stereo sound? DHT

>From Apple's 2300 devnote:
"Sound: The computer has a built-in microphone and speaker. The sound 
circuits provide 16-bit monaural sound input and output." 

Very interestingly however, it uses the Singer sound chip, just like its 
siblings 5300 and 1400 . . .

"Singer IC - The Singer custom IC is a 16-bit digital sound codec. It 
conforms to the IT&T ASCO 2300 Audio-Stereo Code Specification."

And here in the Main Expansion Connector pinout table:
Pin number Signal name Description
67 +8V SOUND Special "clean" +8 V power for sound output
70 +5V SOUND +5 V power for sound output
71 SND OUT R Sound output right channel
72 SND OUT L Sound output left channel
73 EXT MIC FILT R Right input signal from external microphone
74 EXT MIC FILT L Left input signal from external microphone

Of course, that doesn't mean the 2300 actually has stereo output through 
the ExpConn, but I remain hopeful. At least the basic HW _may_ be there 
to support it.
