Hi Julian,

Thanks for your suggestion. However I'm really accustomed to pd-extended and never tried to install externals by myself... and I'm quite short on time to learn this (public show in one month ;-) )

Do you really think this is related to pd-extended ? the way pd-extended interfaces with soundcard/driver is the same as vanilla's, isn't it ?

About the project :
the idea is to have an "autonomous" system with a tiny computer running pd, with microphone input (cheap electret) and a loudspeaker, everything working on batteries. WiFi let me control patches or even write patches through VNC.

On the hardware it's quite fine : i get input/output sound, and the board can run about 6 hours with a 6600mAh battery. Loudspeaker is a commercial battery-powered amplifier with its own batteries. I used to have some noise in the microphone because the wifi dongle was too close, so i got some extra cable and sound is quite good now.

cheers,

Raphaël

Hi Raphaël,

Personally never got to the bottom of that error on Debian with pd-extended 0.43.

Would recommend jumping to vanilla - most libs are available in the repo's.

Hope that helps.

Sounds an interesting project, be keen to hear how you get on.

Regards,

Julian

Hi !

Just to inform you that I'm currently experimenting with Olimex's development boards, this might interest some people here (i am not doing any advertising at all) who are into "mobile puredata"

the set-up i use consists of
- Olimex's A20-OLinuXino-LIME board (dual core Cortex-A7)
- with their own Debian distribution
- cheap USB audio interface : "Terratec Aureon Dual USB"
- pd-extended 0.43-4
- patching through VNC (and through Wi-Fi)

And it works.
..not as fast as on my laptop, of course, but I can run patches ok.
yet, the GUI is indeed quite slow (especially opening a patch)

However, I have a few troubles, but it might not be the right place to ask...
I am newbie to debian, so I couldn't setup jack at all. I'm using alsa but I get the error at startup :
"ALSA output error (restart failed): Broken pipe"
(and also sometimes when opening patche, I get a bunch of these and DSP get stuck, i need to turn OFF and ON again pd's DSP to get audio back.)

Searching the archive, I saw that some people got the same problem and resolved it by suspending/de-installing pulseaudio.
But it seems that pulseaudio isn't installed here.
Maybe someone has got a clue, where to search...? (i know this is very specific problem !)

all best,

Raphaël
