Hello,
I thought I had resolved a problem last night, but that's not the case -- problem still exists.
My Equipment:
Windows XP PD 0.35 test 28 My ASIO software: WDM my command line: C:\pd\bin\pd.exe -asio
My hardware: Edirol UA-5 (Edirol is a division of Roland apparently). It is a USB 2-channel input-output device capable of 44.1, 44, 96 sample rates and ASIO WDM compatible. The device is similar to the new Digidesign MBox with a few more features. The device works great in PD with standard drivers - except the latency is annoying. And (as far as I can tell) it works in Cool Edit Pro with the ASIO drivers, but PD causes the following problems when I use the -asio flag:
- Error -9999 occured opening portaudio stream
- Error Message: Invalid number of channels.
- PD then runs at a turtle's pace; it seems that CPU overload causes the system to work in slow motion. So slow in fact that I haven't ever tried to open a patch or test the audio device further.
I understand that these problems are likely being worked out over the course of developing PD's next release. However, I thought I should make this problem known.
Regards, Dave Sabine
Hi Dave,
I'm stumped over this one. It's conceivable that the ASIO driver wouldn't support two channel I/O (maybe you have to open more channels?) or perhaps the driver won't handle input and output simultaneously (so try "-noadc" and "-nodac" to see if either helps...)
cheers Miller
