Pd wont run with that setting:

kjetism at hensten ~ $ pd -audiobuf 29 -blocksize 1024
couldn't open MIDI input device 1
couldn't open MIDI output device 1
opened 0 MIDI input device(s) and 0 MIDI output device(s).
Sample width set to 4 bytes
ALSA: set input channels to 12
alsa: set output channels to 10
ALSA lib pcm_hw.c:454:(snd_pcm_hw_start) SNDRV_PCM_IOCTL_START failed: Broken pipe
snd_pcm_start: Broken pipe
audio I/O stuck... closing audio


Cant get it to start with a blocksize higher than 128.
