sure, but it's very handy to use the built-in speakers of a laptop.

Have you tried running JUDAS on that laptop and fiddling with the mixer settings in that software? Perhaps it supports unmuting the line-in and keeping it open once you exit the application. To be honest, I haven't tried JUDAS myself. I just safeguarded the source code on GitHub with the intent to study how it drives AC'97 and Intel HD Audio hardware from within DOS.

I guess writing a simple unmute tool would be a simple first project to become familiar with programming this kind of modern audio hardware in DOS. It would undoubtedly be much easier than writing or extending a full-fledged Sound Blaster emulator. 😀

Very handy seems to be a dss with a covox or you can go for an opl2lpt, all such things are VERY usefull in plain Dos with a modern system like a notebook.
No I have not tried judas yet.

I don't what you these for temu303 and vsb103?

vsb103 is version 1.03 of Virtual Sound Blaster, a Sound Blaster emulator that can output to the internal speaker or a Covox Speech Thing on a parallel port. temu303 is version 3.03 of the Tandy Emulator, which can emulate Tandy, PCjr, PS/1 and even the Disney Sound Source on either the internal speaker or a Covox Speech Thing on a parallel port. See the documentation for more info:
