Hi,
I'm trying to install pd on an Athlon with Debian 2.4.18-bf2.4 and the RME HDSP. Sound works both with oss-compatible apps (xmms, which autoloads snd-pcm-oss and snd-timer-oss) as well as with alsa apps. PD compiles and works in 0.35-0 and 0.36-10 with the -noaudio option (also midi from the RME card works well).
When I try to start with "pd -channels 2 &" the computer freezes completely (it prints out a short message about a OSS blocksize adjustment to 2048).
The very same setup works without any problems on my laptop.
Any ideas (I could send some logs if someone is interested)?

Are you sure that you have the very same alsa installed ? Recent ALSA snapshots are known to have broken OSS emulation.
(and it surely is a bug in the driver, because there should be no way how a application with normal user privileges can freeze a machine, ..)

No. I'm sure I have a different ALSA installed. Unfortunately the old ALSA hdsp driver didn't work on the Athlon... (sigh).
I will check again. I got sound working now with pd-0.35-test29 and Stefan Kersten's sndlib patch by not using the OSS layer, but I'd rather use more recent pd versions.
Thanks for the hint. I guess I'll have to wait :-(

.... to be more precise, I think the very, very recent versions could work, but you probably have to use a CVS snapshot ..
Then there is the jack solution too, but this has a minimal latency around 10ms unless you tweak the kernel.

I think not too much changed in sound I/O, so you might get away by using the sndlib with a recent pd version ...
