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:

1.  Error -9999 occured opening portaudio stream
2.  Error Message: Invalid number of channels.
3.  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
