Hi,
I wanted to use two soundcards for input, my built-in stereo soundmax and an rme multiface (for output only the rme). I tried the following parameters,
asio audioindev 2,13 (2 is soundmax, 13 the rme) audiooutdev 12 channels 18 audiobuf 40
but it didn't work, only one device was taken by pd, the rme. Is it possible in windows to have 2 different soundcards working?
Thank you,
João Miguel Pais
I have only done this in Linux, but here are some thoughts:
- are your device numbers *really* 2 and 13? In my experience, they start at 1, and are numbered sequentially, meaning that you'd have to have a lot of sound cards in your system to get all the way up to 13. - when you list channels, you typically give a number of channels for each sound device that you're using, and I always list in and out separately, as in:
-audiodev 1,2 -inchannels 2,2 -outchannels 2,2 (meaning that I'm using devices 1 and 2, and each one has 2 ins and 2 outs) -David M.

actually, i have never done it, but wouldn't you have to link the clocks of both audio devices in order to avoid timing problems?
wini one told me that one can combine devices with alsa, which includes some code, that actually synchronizes multiple audio-devices by software, which includes resampling in order to avoid timing problems ... iirc, pd doesn't include such error correction, so it might be a source of unwanted audio dropouts ...

yes, I've heard that alsa has the ability to create a single, "virtual sound card" from multiple individual cards, but so far I haven't been able to make this work - I'm interested though, to hear from anyone who has done it. also heard a rumor that new versions of jack may be able to connect to multiple cards at the same time - again, I don't have specific info, but am curious to hear if anyone has done it.
to find the post online about wiring the clocks together from multiple sound cards, google: el cheapo howto

argh ... i'd somehow prefer the software solution :P
