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 Touch seeded packages, which is subscribed to sound-theme-freedesktop in Ubuntu. https://bugs.launchpad.net/bugs/1703946 Title: Dedicated mono test sound is unavailable Status in sound-theme-freedesktop package in Ubuntu: Fix Released Bug description: When testing stereo speakers you get the "Front left" and "Front right" samples, but no such sample exists for mono speakers e.g. HSP/HFP bluetooth devices. Instead you get played the "audio-test-signal" which is white noise. To begin with I thought this was a problem with Bluetooth or the speaker itself, but it's just the sample being used. There is a bug upstream to provide this sample, but in the meantime I think playing the "audio-channel-front-center.oga" is a suitable standin.
