Hi,
Now I am able to repeat what you did. In my .pdsettings file, I use
flags: -oss -r 8000 -audiobuf 10 -inchannels 0 -blocksize 1024 -
outchannels 2
As far as I can tell, it only works for the sampling rate fs=8kHz. For
example, if I use -r 16000 instead (or other faster rates), then pd
still runs at 8kHz. In order to compensate, pd does weird things like
counting ms only half as fast (i.e. "metro 1000" behaves like "metro
2000" normally would behave), and osc~ produces output at half the
frequency specified, etc.
Do you all agree that this is a problem with the drivers for audio on
the Beagleboard and not with pd? (Although mplayer and mpg123 can use
the ALSA drivers just fine apparently running at normal sampling
rates, pd doesn't seem to work at all with ALSA, and neither does the
version of chuck that I got using "apt-get install chuck".)
Thanks,
Ed
PS. BTW, in contrast with your wiki, I didn't have to modprobe snd-pcm-
oss, but I did have to
sudo apt-get install alsa-utils
sudo apt-get install mpg123

Great news. Is there a page on the puredata.info wiki on the Beagle
board yet?
If not, can add you install steps to it, or at least notes on
getting the audio
to work with pd?
I wonder why alsa has troubles ... when using oss, can you still use
alsa midi?
I have thought of trying a beagle board but no midi would be a deal
breaker for
me

hi all,
i fixed my issues with Pd on my Beagleboard running Ubuntu. the
solution (thanks
to Julian Oliver's help) was to load the oss module (sudo modprobe
snd-pcm-oss)
then run pd using the oss driver (pd -oss), and it sounds just lovely.
thanks for the other help nonetheless!
cheers, damian
