I might help a person set up an installation which contains both video and sound all running in pd, and is now giving some free advices.
He needs 4 audio outs from pd, so I reccomended the delta44 soundcard. He asked if it was possible to use a cheap soundcard instead (I presume the soundquality is not that important for this). But I have no idea how well that works.
Anyone have experience having 4 outs (an "adc~ 1 2 3 4" object) on a cheap soundcard (one of those 5.1 cards or something) in pd. Does it work?
Pd is going to run linux.

a cheap soundblaster 5.1 should be working fine. im running a audigy 2 with only one problem, that is either i have multiple outs, but no ins, or having 2 outs and 2 ins. if input is not needed, everything should be fine. before i was running 2 cheap normal soundblasters, which is also no problem, except that sometimes the outputs run a little bit out of sync. if you do no rhythmic stuff, thatll be ok.

hi! i've never used a cheap 5.1 soundcard for that purpose, but ionce tried to use 4 channels on a sb-pci 128 and the crosstalk between the two outlets was too big. i ended up using 4 soundblastercards in that one machine for 8 (mono-)channels, which worked well. regards d13b

Any SBLive! card will have 4 outputs with the kernel OSS compatible drivers. Note that the front output may need to be attenuated 12dB (internal analog boost in ac97 codec on the card). SBLive 5.1 cards will have outputs :-)

When I bought my new PC there was only the built-in sound card, an Intel i810 with 6 outputs. For this card, there is a little menu (in the OS parameters) that helps you specifying if you want to work in stereo, quadraphony, 5.1 or with headphones.
I havn't managed to use separate outputs from this card with Pd yet.
Anyway the command line "pd -listdev" (non-implemented in Linux yet) doesn't list the outputs separately (like for professionnal Delta 44 or Hammerfall cards). The i810 is only listed as one input device and one output device (no matter how it is configured)... I don't really know the difference, because "dac~ 1" and "dac~ 2" refer to "left channel" and to "right channel" with the i810 ; maybe it is related to its having only one 3.5mm stereo jack for "two" outputs ?
I should try again this evening for more information.
Maybe it depends on the card ; nonetheless try "dac~ 1 2 3 4" rather than "adc~ ....." if you are interested in 4 outputs :-)

This is probably better on the LAU list.
Some cheap soundcards will copy a stereo stream over front and rear giving the impression of surround sound.
However I have a cheap cmipci < $10 which has two seperate devices nodes for front and rear and you could use each side of the stereo channel as a mono if neccessary. Not quite the same amount of control as the pro cards though. Concievably, with an appropriate .asoundrc multi device I could run jackd in playback only mode then access the front and rear at the same time through any jacked app.
I use the multi device so I can access all four channels on my quattro but haven't tried to use it with the cmipci as I don't make music with it.
my pal steve managedto do this with i believe an sb live. we also did it with multiple cheapo consumer cards, but i dont advise it since the cards buffers empty at slightly different rates which can result in a near constant crackling sound. here is his message:
I think if you get the emu-tools package from here: http://sourceforge.net/projects/emu10k1
you can use it to map the rear channels to the second PCM device. I don't remember the exact syntax, but you want to map front to PCM0 and rear to PCM1.
I had a script that did it, but it probably got erased when we did the reinstall

Actually, the driver that is in the Linux kernel (at least the one that comes with Mandrake) has this set up by default. dsp0 for front, dsp1 for rear and dspw (?!) for center/surround. This is with the kernel OSS compatible driver and _not_ ALSA.
