Probably so. The server runs a Sempron 3000+. The onboard sound (which
I've never used) has only 3 jacks on it. IIRC, one is Mic In, one is
Line Out, one is an amplified output signal. The server has an AOpen
AW320 PCI sound card (Crystal Audio chipset) in it, but ALSA apparently
can't find it or can't drive it when it does find it ... The AW320 has 5
connectors on it, I think ...

My Toshiba laptop (bought in 2004, so I guess it's old now, too) has Mic
In and Headphone out.

Well, QJackCtl shows me two readable ports (capture_1, capture_2) and
two writable ports (playback_1, playback_2). But there are only two
physical audio ports on the machine - sound goes out one and not out the
other - so I guess JACK is seeing the left/right sides of each one?
Anyway, to date, I can't tell if sound fed into the microphone port
actually gets anywhere - attempting to record anything fails, some silly
artifact of using Intel 8x0 chipsets, I'm told.
