Hello,

I'm begining to play with Pd with a Snowball ARM-based board from Calao Systems ( http://www.calao-systems.com/articles.php?lng=en&pg=6186 ). I'm using pd 0.43-4 compiled on it with linaro-ubuntu. it sounds pretty well thru the minijack output... I have only some difficulties to know why it runs when it should not - the behaviour seems to be quite different than pi or bb board as I can read on last posts :

• the first time I tested pd on it, I played thru pulseaudio (ubuntu default) , using -alsaadd but the audio was very unstable
• now, after having autoremoved pulseaudio, I'm using alsa, the minijack is the card 0 device 1 (from 0):

$ uname -a Linux linaro-ubuntu-desktop 3.3.1-37-linaro-lt-ux500 #37~lt~ci~20120524012446+1337874072~4fbea4f1-Ubuntu SMP PREEMPT armv7l armv7l armv7l GNU/Linux

$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: U8500card [U8500-card], device 0: hdmi av8100-codec-dai-0 [UX500_PCM] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: U8500card [U8500-card], device 1: ab8500_0 ab8500-codec-dai.0-1 [UX500_PCM] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: U8500card [U8500-card], device 3: cg29xx_0 cg29xx-codec-dai.1-3 [UX500_PCM] Subdevices: 1/1 Subdevice #0: subdevice #0

with hw:0,1 declared in file /etc/asound.conf I do : $ aplay -D hw:0,1 son.wav = aplay son.wav (= OK)

but, with pd it's different : $ pd -nomidi -noadc -alsa -outchannels 2 -r 48000 -rt -audiobuf 50 -blocksize 256 patch.pd gives nothing but the default outpu of the card (hardware = hdmi probably = device 0), with no access to the minijack output (second device ), nore into audio menu setting...

then, the only way to have audio output to the minijack is to run pd -alsaadd and audiodev 3 - please note stranges characters for audiooutdev 3: $ pd -nomidi -noadc -alsa -outchannels 2 -r 48000 -rt -audiobuf 50 -blocksize 256 -alsaadd default -audiooutdev 3

I see no clear doc othger than the help seems to be too short...

Thank's you for your help, Fred
