Hi, It could be that you are using MME, which only supports 2 channels per device, you need ASIO for this. I believe that if your card doesn't have ASIO and doesn't show up as several outputs when using MME, pd cannot talk to it multichannel. You couls try asio4all, but I think I've heard it's not working multichannel... Cheers, Andres

Subject: [PD] multichannel with SB Audigy 2 (winXP)

hello i'm a new user of Pd. I use the 0.37.2 version on winXP with a Sound Blaster Audigy 2. my problem start when I try to use 4 (or more than 2) audio outputs. I check the -listdev and it shows something like this:

input devices:

1. SB Audigy Audio [DC00]
2. Lýnea #0 del modem

output devices: 0. SB Audigy Audio [DC00] 1- Lynea #0 del modem API number 3

midi devices work fine, thats why I dont include them. the only way that Pd works fine is when I run it with -audiodev 0 -outchannels 2 but if I run it with other configuration like -outchannels 4, or -inchannels 2 -outchannels 4, or others specifications of de audio device it appears an error, it's something like this: (It has been translated from spanish, so I hope it's understable for you)

12 audio buffers: waveInOpen: the specify format is not compatible or can not be traduce. Use the capacities function for determine the compatible formats. Wave out open device 0 + 1 waveOutOpen device: the specify format is not compatible or can not be traduce. Use the capacities function for determine the compatible formats. resyncing audio 12 audio buffers 12 audio buffers

Pd audio works but only stereo, the dac~ 1 and 3 sounds together, the same 2 and 4. I tried some solutions that appears on the list, but anyone serves me. the 6 outputs of the SB works fine in other programs, but Pd only use 2 of them. if you have any answer, or question about this problem, tell me please!!!!!

best regards
