Hi,

did you downloaded the coccinella binary from the coccinella website, or did you installed a ubuntu package?

do you actually have sound at all with the client?

I updated from OpenSUSE 11.1 to OpenSUSE 11.3 recently (x86_64), and I also see some problems:

without jackd running:

Cannot connect to server socket err = No such file or directory

Here when coccinella starts up:

and then additionally I see the following error popup window appearing:
Hook afterFinalHook failed: 1
No such device: /dev/dsp
    while executing
"snack::audio selectOutput $sprefs(outputDevice)"
    (procedure "InitPrefsHook" line 34)
    invoked from within

    (procedure "::Sounds::AfterFinalHook" line 20)
    invoked from within

    ("eval" body line 1)
    invoked from within

however, /dev/dsp exists, and I can access it.
Then In the preferences I don't have the sound menu.
For me on my OpenSUSE box it looks like kind of srew-up of alsa/portaudio/jack???
portaudio version is : portaudio-19-265.1.x86_64
alsa version is: alsa-1.0.23-2.12.x86_64

Above was with self compiled dependencies, and using source tarball of coccinella. 
Using the binary from the websiteI see the following:

Expression '*idev = open( idevName, flags )' failed in 'portaudio/src/hostapi/oss/pa_unix_oss.c', line: 797
Expression 'OpenDevices( idevName, odevName, &idev, &odev )' failed in 'portaudio/src/hostapi/oss/pa_unix_oss.c', line: 851

PortAudio error at Unable to open streams: Illegal error number


It works fine for me on OpenBSD, there portaudio version is: portaudio-svn-1406p1.

Sander, what do you see on your Linux box?
