2 things:
- the "snd_pcm_open (output): Device or resource busy" issue is, as
Iohannes said, due to the -nogui bug. Put a delay on your "dsp 1"
message. I use 100 ms.
yeah, fixed that, thanks!
- the crackles are probably coming from dropouts due to pd not
running in realtime. Try this and use alsa: http://puredata.info/docs/tutorials/HowToRunPDWithRealtimePriorityInUbuntu
. I have not problem on a slow machine using alsa and -rt without
Jack.
ok, did all that - now i think it worked because with the -rt flag
the gui was extremely slow, but the messages to the console were
'proirity scheduling 6' and 'priority scheduling 8', not the 98 i
was expecting.
in any case, sound output (full of clicks) is exactly the same
running -rt as running without.
the only way i was able to get something that even vaguely resembled
what i was expecting was by using the -blocksize argument to set a
blocksize of around 16384 or more frames... but even then it was
still full of clicks, it just didn't sound so stupid.
Can you get any audio app working properly on the beagleboard? I
vaguely remember something about bugs in the ALSA driver for that
hardware.
