[PD] amplitude overload

[Oded Ben-Tal]

I'm encountering some strange behaviour. I'm running PD on linux (rh9 
planetcCRMA) using maudio quattro sound card. It worked fine yesterday, 
but today I get amplitude overload and some errors. The test audio is 
distorted and I had to reduce the amplidute by factor of 10 in a patch I 
was working on to get acceptable levels. 
I'm using jack:
jackstart -d alsa -d hw:1,0 -r 44100
which complains (semi periodically):
*** alsa_pcm: xrun of at least {8.732-30} msecs

I ran the exact same thing yesterday with no (noticeble) problems and I 
haven't changed anything since.
