Yes, the internal one is used for listening generally. The USB one is to be used with jack but that is not working either right now.

This is a rather unique motherboard in that it has two ISA slots (something hard to come by these days). Intel chipset, only one IDE pair, full complement of SATA. 64 bit processor, running 32 bit now but will switch over once qt4 and kde are consistent on Sid and all those held packages are resolved.

 

One ISA is used for another sound card which the system knows nothing about, an old Yamaha sw60xg sound generator. Using Yamaha's advice for Windows 2000 before they made a driver, set the switches to a port and use mpu401 on the port number. No DMA, No IRQ, nothing.

 

I had an older speakerphone modem on the other ISA but that ceased to work. PCI modems that work with Linux are hard to come by since most use Windows software rather than their own hardware. I am using an 'antique" external modem until I find something else.

 

Another 4-in/4-out dman2044 PCI sound card I had on Windows 98 has no support beyond that, which is a pity, good card, breakout box, etc.

The master controls all.

I have front going to the speakers

I have center going to subwoofer (since its feed-through is problematic).

The checkboxes on alsamixer or qasmixer will switch these outputs.

Headphones do not work--programs have no toggle for it.

 

Things are going throught the hw0,0 "analog"

The hw0,1 "digitial" does not play, there is no spdif connected on this board.

There are six jacks on the back, not 8.

I know nothing about his (be recall have seen something about it).

 

The other problem is that the line input seems dead which renders the card useless for any wired connectivity. Could be a real hardware problem but how often does that happen.

 

Worse comes to worse, I have an old ens1371 laying around which I could use, hard-connecting the speaker line and the woofer-line.

Good. This is apparently not the only system with problems with 3.2.4
