Hi

I looked into the SBLive drivers to see if I could make them work with 4 outputs in PD. So far running -outchannels 4 just mixes the signal of dsp 1-4 to front and rear out which is pretty useless.

Anyway, I dowloaded the latest snapshop from htp://opensource.creative.com and compiled the drivers and utils. To make PD use 4 channel sound the dsp and dsp1 has to be directed to the front and rear. The program that does the trick is dm (digital mixer) which can be found in the utils dir. The program is very badly documented but I found that:

./dm front dsp 0 ./dm rear dsp1 0

sets dsp level to 0 in front and dsp1 level to 0 in rear leaving dsp in rear out and dsp1 in front out. Viola! 4 channel sound. All one has to do now is to calibrate the outputs. The levels are set with similar commands. Don't touch other mixer programs since they will reset the dsp front/rear levels. There is a GUI available for dm at http://perso.club-internet.fr/bea_raph/

I cannot make it work.

Btw, the rear out is stereo mirrored!

Will make futher tests tomorrow :-)
