Sound (Users)

Hi all!


When I think on DOS, I always remember that it took me close to one hour to find out how to access the Quattro Pro menus, many years ago...
This is a very nice project!

I've installed FreeDOS on a mini-itx board with an old Atom i386 1C/2T processor.
The problem I'm facing is about having no sound, at least from the back connector. Have no connection to the front jacks, but can find a way if there's a possibility to have sound from there.

From the manual of the board:

Intel Desktop Board D945GSEJT has a 2 + 2-channel (stereo) onboard audio
subsystem that includes a Realtek ALC662 audio codec.
The subsystem includes the following headers and connectors:

Front panel audio header (supports both AC ’97 and Intel HD Audio) , including
functionality for:
? Line out
? Microphone in

Back panel audio line-out connector

S/PDIF header (3 pin)

Internal mono speaker header (2 pin) for support of a 1.5 W/ 8 ? speaker
The front/back panel audio connectors are configurable through the audio device
drivers.

Desktop Board Features
The audio stream for the line-out port is routed according to the following
dependencies:


By default, the audio stream is down-mixed to mono and amplified for an internal
mono speaker.
If a connection is detected at the back panel line-out port, the audio stream is sent
to the rear line-out port and the internal mono speaker is disabled.


I've already searched the forum and it seems that the supported cards are SoundBlasters.
But there's always hope.
Is there a way to have sound from such a board?
Or is there any emulator or converter from SoundBlaster to AC'97?

Thanks.
