Thanks for the suggestions. I've tried as you suggested but had no success, either when running as normal user or as root (using sudo). I'm now going to experiment with Faust -- if the error persists, then the problem is likely to be related to the audio layer itself.

These are the two invocations I've tried:

pd-extended -path $PATH -open $PATCH -nogui -alsa -channels 2 -audiodev 1

and

pd-extended -path $PATH -open $PATCH -nogui -alsa -channels 2 -audiodev 2

(Where $PATH and $PATCH are my actual directory and file)

The first invocation produces the ALSA output error (restart failed): Broken pipe error, whereas the second produces the error: audio I/O stuck... closing audio error.

I've also just tried the vanilla PD you linked to. In the "Test audio and MIDI" dialog, I can make it output noise, but nothing else. Moreover, the debug console shows displays tried but couldn't sync A/D/A, which doesn't sound too encouraging...

I'm trying to use pd-extended on an ARMv7 platform Radxa Rock Pro. This is a fairly powerful 4-core ARM Cortex-A9 based system with 2GB of RAM, running Debian Wheezy with kernel 3.0.36. The pd-extended version is 0.43.4-1, which I've compiled myself from source.

Unfortunately, I've so far been unable to make pd-extended produce any sound. Upon startup it always complains with either a ALSA output error (restart failed): Broken pipe error (when using -audiodev 1) or a error: audio I/O stuck... closing audio error (when using -audiodev 2). The available audio devices provided by -listdev are as follows:

audio input devices:
1. RK29_RK1000 (hardware)
2. RK29_RK1000 (plug-in)
3. ROCKCHIP-SPDIF (hardware)
4. ROCKCHIP-SPDIF (plug-in)
audio output devices:
1. RK29_RK1000 (hardware)
2. RK29_RK1000 (plug-in)
3. ROCKCHIP-SPDIF (hardware)
4. ROCKCHIP-SPDIF (plug-in)

(I have no way of testing the SPDIF output).

Note that running speaker-test -t wav -c 2 works as expected, and I've added my user to the audio group.

Anyway, has someone managed to get pd-extended running on an ARM-based device? Is the problem related to PD itself or could there be a bug in the sound driver for this particular board? Or is there something else I should try? Thanks in advance.

@smark: Not sure, but maybe this version could work on your setup:
https://puredata.info/downloads/pd-extended-0-43-3-on-raspberry-pi-raspbian-wheezy-armhf/releases/1.0

It does, thanks!

I'm a newcomer to PD, and obviously the first step towards playing with it is to actually get it compiled and running on my ARM machine (armhf). I've followed the steps outlined in the PD site, but unfortunately the compilation fails after a long while (see error log at the end). The compilation error smells like an autoconf/automake version incompatibility, but I'm not sure if that's really the case. I'm running the following software versions:

• OS: Ubuntu 14.04
• autoconf: 2.69-6
• automake: 1.14.1-2ubuntu1
• pd-extended: 0.43.4 (this is what I'm trying to compile, of course)

Any idea of what the problem could be and how to fix it? (Alternatively, if you could point me towards pd-extended binaries for armhf I would be much obliged!)
