f18 audio problems

[Mike Wright]

Hi all,

My f18-xfce install has serious bugs in its audio programs.

1) There is no volume control popup.  The only way to view the audio 
level is to use the application's Multimedia->Audio Mixer and/or 
Multimedia->Volume Control.  On Audio Mixer the Master control responds 
to the keyboard volume controls.  On Volume Control->Output Devices also 
responds.  Panel applet Audio Mixer seems to off in a world of its own.

2) Panel applet Audio Mixer (different than Multimedia->Audio Mixer) 
disappears on mouse out even when set to "Always on Top".

3) Multimedia->Audio Mixer->Master when moved to zero volume via the 
mouse causes Mute on both Multimedia->Audio Mixer and Multimedia->Volume 
Control.  Raising it leaves Multimedia->Volume Control muted.

4) Multimedia->Volume Control->Input Devices->Port->Line In volume 
setting have no effect.  Multimedia->Audio Mixer->Line-in responds to 
mouse control raising and lowering the input level.

5) Line Input seems to have escaped from the rest of the audio system. 
While applications respond to volume adjustment Line Input remains fixed.

6) Moving any volume control to zero mutes Line Input; raising it 
returns it to a fixed level (all or none).

7) Occasionally the panel Audio Mixer applet does control line input 
volume but I have yet to determine how or what causes that to happen.

This seems to be one of those situations where "the left hand doesn't 
know what the right hand is doing".

Anybody have any insight?  Others noticed this?

Thanks,
Mike Wright
