from terminal :
readPartial readPartial readPartial readPartial readPartial readPartial readPartial readPartial readPartial readPartial readPartial readPartial readPartial readPartial readPartial readPartial readpd_gui: pd process exited
Segmentation fault

Just started for some reason.

Can anyone enlighten?

alsa works but is not desired.

Never seen that before myself. Try

sudo killall pd
sudo killall pd-gui

then try launching again.

The only thing that worked was setting the sample rate on both jack and pd to 48000 instead of 44100 for both. lashd was hanging too. Nothing kill -9 couldn't handle

thanks for the help.

Is that maybe a sound card issue? 48000 is a consumer rate standard, whereas 44100 is (or was) meant for higher quality audio. Ass-backwards, I know, but there's the industry for you.

It might be freebob. I'm using a Presonus Firebox, jack-audio-connection-kit, and libfreebob driver for jack. It seems using higher sample rates yields better clock syncs. Go figure. . . It's working better now.

I've been tweaking my setup as of late; I went with Arch Linux x86_64 w/ kernel26rt with preemption patch, got jack and freebob working, nvidia 177-rt, etc . . . something was bound to break.

Well, it's back.

There's probably a hundred or so of these . . .

I'm sticking with alsa until this is sorted out.

Seems related to memory lock and jackd. Disabling memory lock for jackd allows Pd to stay connected to jack without the Pd segmentation fault. Can anyone explain this?

And then it crashes... same here, with Debian Lenny(amd64)/jackdmp/freebox/firepod but the unlock memory trick doesn't work for me. And jackd won't start at 48k. I think it has to do with freebob. Maybe I'll try to have a go with ffado. I'll report back if success.

Correction: jackd will start at 48k, but only after a reboot of the firepod soundcard! And will come back to 44,1k only after reb... ffado didn't change anything. And memory lock neither. Anyone has a clue?

I ditched Arch and my custom preemptive kernel and am using Ubuntu 9.04 X86_64 with the linux-rt kernel. looks like it works well again.

I totally messed up my lenny yesterday (it was late and i's tired ) and decided to give a go at 64studio 3.0 beta3 (amd64) today. This distro is based on hardy heron.

It seems to be better, but i still got i/o errors.

I wish 64Studio worked for me. Last time I tried it did not have a firewire stack included in the kernel.

Nevermind Ubuntu-Studio, the repo version of freebob started locking up my Firebox. Well, it might be time to either change interfaces or distros. Gentoo, I'm looking at you!
