Hi
I've installed Pd-extended on my Raspberry Pi with a Wolfson audio card. The first time I started it it gave me the error "Audio I/O stuck, closing audio" despite this I still had sound. After shutdown and reboot of the Pi Pd gives the error "Alsa input error(restart failed)cannot allocate memory" and the same for output. It scrolls this error repeatedly before displaying the audio stuck message again after this there is no audio. Can anyone please help?
Thank you

Hi all,

I've been trying to build Pd extended on my raspberry pi. I've been following this guide.

http://puredata.info/docs/developer/BuildingPdExtendedForRaspberryPiRaspbianWheezyArmhf

And everything goes fine up until this line

sudo dpkg –i Pd-extended_0.43.3-20121010.deb

Which returns the error: dpkg error need an action option

I have changed the numbers in the line to represent the .deb package that has been created (as per the guide)

Could someone help me see what is going wrong please?

Thanks

Sorry guys, I've only just woken up, of course I'm having problems installing not building. The package has already been built.

Hello this is my first post here so apologies if I get anything wrong

I'm doing a project for University that involves using the Kinect camera to trigger audio and video whenever someone steps in specific zones within a room. I have made all my patches and believe I have it all working except for one problem. When I run the audio and video patches simultaneously I get distorted almost echoey audio. There is no audio in the video so I don't think that is the problem but I am lost as to what it could be. Could anyone help please?

Strange, that worked for me. The only other changes I had made were to overclock to 1GHz and alter the memory share. As I was using the PI headless I wasn't too concerned about graphics.

I fixed it by adding
-audiodev 0
as a startup flag. This seemed to get rid of the memory allocation error. Still get the odd error that pops up but it doesn't affect the sound at all. Hope this helps.

Solved it thanks. Ihad typed the filename wrong

The problem is present when manually controlling the audio and video patches at the same time without the kinect patch. So I don't think it is a problem with that patch. I can run the kinect patch and audio patch together with no issues also the kinect and video patch. The problem only occurs when the audio and video patches are run in unison.

Thanks

Thank you for the reply

I thought the same about the CPU and pd's CPU meter patch does report 110%.
But the system monitor within OSX reports just 20%. As for the kinect patch I'm using a slightly modified version of TUIO dispatcher and I do have quite a few number boxes in there at the moment, just for debugging and set up purposes, these will be removed for performance. The trouble is that this anomaly happens when running just the 2 patches I posted, without the kinect patch. I am running a fairly powerful setup, core i7 3770k, 16 GB Ram, gtx 650 ti boost and Allen and Heath Ice 16 sound card. I tried increasing audio buffer to 50ms but this just crashed pd. but as I say this happens with just these patches running. Can you see anything within these patches that may be causing this. If it helps at all the samples that are being used in the muted player are wav format 16 bit 44100 and quite short, the videos are mov format and all three patches and media together are just over 12 MB.

Thank you again

Sorry could only attach one patch, this is the audio player
