Hi Miller,

audio I/O in Pd seems to be a problem under Win2k in general - or I just have the wrong hardware...

Since latency was not a problem in this case (but I need full duplex), I increased buffersize to the upper limit - no success. Using a PCI soundcard (a Yamaha waveforce which costs a bit more than $10 und worked perfectly all right unter WinNT) resultet in Pd eating up 100% CPU when I started it the first time. Starting Pd a second time worked better but about every two minutes CPU usage jumped up to 100% for about 30 seconds - but with audio I/O not closing! Then I used the standard Win trick "format c:" and started again only installing the hardware I really need. This seems to work. Tomorrow night will proove.

I'll try to investigate this issue a bit further in case I find the time. I'm just wondering if there's anybody else having this strange problems...?

BTW I once wanted to try jMax - it did not work. After I changed to the Yamaha card it works. So everything I know is: don't use on-board soundcards...

HI Olaf,

if you can do without sound input, run -noadc (or vice versa, "-nodac".) Otherwise, try increasing audio buffer size... I've seen some audio hardware that just freezes unexpectedly when running full duplex, probably because the drivers are buggy. As a last resort, invest $10 in a PCI soundcard...

cheers Miller

Hi list,

I have some problems getting reliable audio I/O with Pd (0.35 test 11). After a few moment I get "audio I/O stuck... closing audio" and have to restart Pd to get audio again. DSP processing still works (I can listen to an ogg vorbis stream that I send with Pd).... BTW. this happens under Win2k Prof. using the internal soundcard (Analog Devices with SoundMAX driver).

Any help is very appreciated!!! - Because I have a performance on Thursday and really need audio I/O!
