Hello all

I'm helping my daughter (a final year Arts student) put together an audio installation with eight speakers using this device:

http://www.ebuyer.com/product/106540

using Pd running on a Windows XP machine.

I thought it might be as simple as selecting it as the sound device (via Media->Audio Settings), ensuring the number of channels is set to 8, and then creating a dac~ object with 8 channels, [dac~ 1 2 3 4 5 6 7 8], connecting the various sound sources to one of the 8 channels.

I'd test this out but she is in Reading and I am hundred miles North, so instead I browsed through the documentation and help files to see if that understanding is correct.

In the Help file [pd multi-channel_audio] I found some information on using ASIO drivers (via "portaudio"), and now I am not sure whether my initial simplistic understanding still applies!

Any help to use all 8 channels this external soundcard easily would be much appreciated!

Many thanks in anticipation

I haven't fired up my Windows machine in a while, but I believe you can select portaudio from the Media menu. I think it's default, though. Did you also set the number of input channels to 8? Portaudio needs input and output channels to be equal.

Also, the ASIO drivers would probably have been included on the installation disc. Portaudio communicates with the ASIO drivers by default, so if you select portaudio, you'll be using ASIO.

Thanks, M.

I spoke to my daughter yesterday and she reports doing exactly as you suggested, but only getting sound out of two speakers (one stereo channel).

I'm intrigued by your comment about the ASIO drivers on the installation disc, though - she's not the most computer literate person in the world, and she has undoubtedly just run the installation program for the device, which may or may not have installed the ASIO drivers.

I'll try to speak to her today again, and investigate further to see if I can find out why there's only sound on two channels.

Thanks again!
