sound: Testing mono output plays back noise

Bug Description

When having a mono output source, such as BT HFP/HSP, unity-control-center by default plays /usr/share/sounds/freedesktop/stereo/audio-test-signal.oga
 - which is a sample of noise.

This makes it hard to know whether the speaker test works successfully, e g, if the sound output is noisy because of some bug, you will not notice (it's noise either way!).

It would be better if the test button was a spoken voice, just like when you test "Front Left", "Front Right" etc.

This is the "code" part of the solution. Then we need someone to draw icons and record sound for these new channels, too.

Thanks David, the change was commited upstream

Could you maybe merge propose the change against lp:unity-control-center?

What is the UI looking like if we don't get new sounds/icons? Do you know what GNOME did for those?

At this point, what we need is actually someone recording the sound and drawing the icons. (Or have GNOME do it for us?)

IIRC, if we merge this patch without new icons and sounds:
 - the sound will fall back the same noise (i e bug remains unfixed)
 - the icon might be worse off (displaying a "broken" icon of some sort). I guess this can be worked around with symlinking one of the existing speaker icons.
