Description Colin Guthrie 2012-04-04 01:54:16 UTC

Reproduce:
(with flat volumes enabled)
1. Set sink volume to something sensible.
2. Set event sound volume to something less than that, e.g. half
3. Mute event sounds
4. Run alsamixer -c0
5. Trigger an event sound.

Watch as the volumes adjust due to flat volume logic!

This can be an issue as if you have event sounds set to 100% and muted, but sink volume to, say 60%, simply playing an event sound (which is muted) will push the h/w volume up to 100% and leave it there.

Thanks for Arun's testing, it's apparent this bug has been present since 1.0 pre-release at least (maybe earlier, we've not checked).
