I am trying to use PD on a Raspberry Pi but I am getting some weird issues. It is telling me that it tried but can't sync A/D/A. I have tried 48k and 44,1k in a lot of different buffer sizes/delay but can not get it to work.
I am also getting this message.

Setup is Raspberry Pi 3, Pd 0.46.2, Behringer 202 usb sound card.

Would be SO happy if anyone could help me out!

Thank you so much for trying to help me out!

$ aplay -L --dump-hw-params gave me this:

I am not running the card with a hub. I see that people have been turning their pi's usb speed back to usb 1 but that it then wont work with a usb keyboard.

Maybe I just need to bite the bullet and get one of those Pisound interfaces?

probably makes no difference but does setting usb audio input as plugin and output as hardware do anything?

could be an issue with that version of pd

i have the latest version working on the pi3. (although do sometimes get errors when creating objects while audio is running)

try downloading the latest stable version
Raspberry Pi 2 or 3 (ARM v7) (10 Megabytes) from:
http://msp.ucsd.edu/software.html

here are the install instructions i followed.

Yes. I'll try to install 0.47 of PD to check. But I don't reeeeaaaallly understand the installation process.

When I typed sudo apt-get install build-essentials automake autoconf libtool gettext I just got an error.

I am doing a fresh install of Rasbpian now btw. It could be that I have broken something earlier.

@kristofferlislegaard i would really try version 48 at least. you also can do:

sudo apt-get update
sudo apt-get dist-upgrade

Thanks for helping me out! I'll get back to you when the dist-upgrade is done

Ok update:

I did a full fresh install from the Noobs card, I then did the dish-upgrade, then i installed version 48(which after a while i discovered there is a typo in the guide, it is supposed to be build-essential not build-essentials) installed everything in the guide, opened pd, change to the external sound card, same problem

If I use my Mixpre-D instead of the Behringer card it seeeeems to be working, but I still get this message:

This message should't be a problem, it's quite often there. As long as you hear your sound card OK, then it's OK. If using ALSA doen't seem to work, give Jack a try.
It's weird, but using Jack with the ALSA driver most of the time works smoothly, while Pd with ALSA alone could have issues. At least to my experience.

Thanks for the tip. Ill think about Jack. But yeah with the Behringer card there are audio glitches.
