Comment 4 for bug 297168

With Ubuntu 8.04 I have done all troubleshooting and with help from the Dutch forum but it didn't solve the problem.
Also if there is a solution with troubleshooting than it is still a bug because the sound have to work out of the box.

After I did this (https://wiki.ubuntu.com/DebuggingSoundProblems) troubleshooting the sound still not work.

When I test the sound in Preferences > Sound I get the following message:
audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Failed to connect stream: Invalid argument
