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 -- Video, Flash and system have no sound https://bugs.launchpad.net/bugs/297168 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
