Here's without booting windows first:

And here's with windows:

bt848-0: < 80+ 13+ 00+ 1e+ bt848-0: < 81+ =03+ =03- >
bt848-0: < 80+ 13+ 00+ 1f+ bt848-0: < 81+ =00+ =06- >
msp3400: init: chip=MSP3400C-C6, registered as sound mixer

Opening the casing of my machine will have to wait.
The windows driver seems to lie about the chip: it calls it a 3400C.
