Comment # 7 on bug 922401 from Christian Bachmaier

If you are asking me, then this is also a bug: playing a sound manually in
control center resets both loudness sliders to 66% instead of leaving them as
they are.

Unfortunateley, no. As I wrote, the automatic login notification (or some
other) resets both sliders to 66%.

Thx, Chris
