The files look right, and I can reproduce this on one of my test machines. I can't reproduce it anymore on an updated daily ISO. So I think this is something machine specific. Looking at the code it looks like canberra is failing to play the "new" sound and so failing back to play the test sound (white noise). I can't work out why it's doing this yet. I need to get more debug info out of libcanberra I think.
This might be futile though, if it works everywhere else. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1703946 Title: Dedicated mono test sound is unavailable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sound-theme-freedesktop/+bug/1703946/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
