I am finally getting around to seeing if I can figure out how to get sound out of this thing.

The attachment E-Tech_PC336ECA-PL.jpg is no longer available

I suspect the headers are as follows:
J1 (4-pin) CD-IN
J2 (3-pin) CD-IN
J4 (16-pin) front or slot panel
J6 (2-pin) Speaker connector for modem.

Original info page from E-Tech about the PC336ECA / PC336ECA-WT, which was the card that supposedly had an output jack instead of the headers.

The text from an article about the release:

E-TECH RESEARCH LAUNCHES SOUNDBULLET MODEM
Thursday 21 August 1997 | 00:00 CET | News
E-Tech Research has launched the Soundbullet, a modem transmitting faxes at 14.4kbits/sec, and data at 33.6kbits/sec. The modem also features 16-bit on-board stereo, v.80 video phone capability, and full-duplex speakerphone. The device also handles diagnostic testing, pager notification, call screening, call progress display, and memory for four phone numbers. V.42bis and MNP5 data compression is also supported, as is V.42 error correction. The Soundbullet also features drivers for Lucent/Rockwell's K56flex, US Robotics' X2 and Windows 95. The Soundbullet costs USDlr100.

The K56flex and X2 drivers are not available from the archived E-Tech USA site and the Taiwan site used an ftp.

The original driver disks contain the drivers for DOS, Windows 3.1 and Windows 95.

This kind of modem+sound combination can either work with a big DSP (driver nightmares like IBM's mWave) or are basically a bunch of unrelated chips on the same PCB.

This looks like the latter, with what looks like a bog-standard ESS ES1868F for sound duty and a regular ES692S connected onboard via MIDI.

I'd configure with default ESS tools or Unisound, chances are the sound part will 'just work' and if you point some game at the MIDI port you configured the ES692S will spring into life.

Right. The tricky part is going to be figuring out the output on the header. The only 3.5mm ports on the back of the card are Line In and MIC In.

Shouldn't be too hard. GND is easy enough to find (continuity with ground). Connect one side of wire to audio device to that, touch the other ones one by one when something's playing.

Yeah, that is my plan. I have a stereo 3.5mm plug that I already had set up for recording directly from the PC Speaker output and I'll just put single plastic covers on the terminals instead of having a 4-position terminal cover on it.
