It might be that the pulseaudio daemon is not running. I know it's not
running in the Beta2 SDK. Try to start it manually, also please have a
look at this bug: https://bugs.maemo.org/show_bug.cgi?id=5168

Thanks for the heads-up, Conny.

But... could there be more things wrong?

I also get an error like that, but without the "symbol lookup error"
part. After that is seems to be running (it's taking connections) but it
does not output audio. Probably because there's already pulseaudio
running on the host. Maybe it's possible to run puseaudio on the host
and make it somehow available to scratchbox?

Sorry that I cannot help you more.

Phonon uses GStreamer. Anyway if ou are using Qt, phonon is the best
solution.

I have the same problem with the SDK and cannot get pulseaudio to run.

I'm working on an audio application so it would be very useful to get sound from the SDK.

Is it a common problem or is something wrong with my installation?

I'm running Ubuntu 9.04, SDK version 5.0 (I think) and have checked that's using the latest pulseaudio 0.9.15-1maemo35+0m5.

I had a small Qt example working with the same error/warming from oil_text_check_impl.

Until I read this thread here, then it stopped working.

i write my application (Qt 4.6.2) using phonon to play wav
effect, but application is mute and i have this message: "do
you not seem to have package gsreamer-0.10-plugins-good
installed"; this package is already installed newer version
Also, i have found this thread
https://garage.maemo.org/pipermail/qt4-devel/2009-May/000514.html
but i don't understand if this problem solved or not

I also have exactly the same error (with Maemo 5 SDK freshly installed and last versions of the packages).

I guess it has something to do with pulseaudio already running on my host system (which I don't know yet how to disable since Ubuntu respawns pulseaudio processes when killed)...
