Hello,
i'm developing some software for company i'm working in, for playing back the
recordings of a telephone calls, radio transmissions and stuff. The
application obviously uses jack audio server and is running on a SuSE 10.3.
Audio has to be played back to the six separate mono outputs, and i am
searching for a sound card supported by a jack. The card should be PCI or
USB. I don't need a hardware mix, and the sound quality can be low, as a
recordings are did in a 4 or 8 kHz - no sound card can make the output worse
i think :)
I've found m-audio 2496 to be fairly reasonable, but i'm wondering if some of
inputs can be configured as an output.
thanks,

Maybe the Delta 1010LT? I don't remember how many outputs it has, though.
Maybe JACK could handle multiple USB audio devices for output?

Why not use the average built-in soundcard in surround mode? That gives yousix
channels (with non-pro quality) at no extra costs...
Have fun,

The quality doesn't matter. I need to buy the pci card, as there is no onboard
sound (yes, it sounds strange, but the box is a 5u rack-mount HP server).
If i understand the jackd correctly, it should pick up the correct number of
outputs, unless defined otherwise. So I'll be able to route my app's ports to
the individual channels of the sound card.
Anyone has an experience with Terratec 7.1? It looks pretty good, ice1724 or
cmi8768 chipset for fair price. Alsa matrix suggests it should work.
thanks,

Ah, so it could do it for the OP.

Just start jackd without any -i or -o and see how many channels you get :-)

give me a list of a cards he have and I'll chose one next week, comparing the

Don't take my word for granted. But the manufacturers tend to save money
whereever they can. And adding a lowpass (not matter how cheap) is raising
the costs... And its impractical since different sound setups need different
cutoff-frequencies. So this is better left to the 5.1 amplifier/speakers.
Have fun,

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.

hi, i have an old soundcard: "terratec phase usb 26" , it works ok
with
Jack and it has 6 rca outputs, it works OK , i made some music using the
6 outputs with this soundcard and no problem at all
the price is just around 100 euros and i think terratec have a similar
pci model (im not sure, you should check )
hope this helps!
