Re: [Bug: 21.4.19] XEmacs Sounds Modulate System Volume Under Alsa and FC4
Hi Randy,
Sorry for the delay. We had a minor problem that held up the mailing
lists for a little bit.

Everytime XEmacs plays a sound, the Alsa mixer volume is increased
momentarily for the duration of the sound (e.g., drum, whip, etc.).
This causes the volume from other PCM music sources (e.g., the xmms
player) that may be active at the time to be modulated up and
down. The amount of the volume change is significant and is very
irritating. This behaviour also makes the sound XEmacs is playing very
loud, in addition to increasing the volume (momentarily) of the other
PCM sound sources.
Specifically, if you start the gnome-volume-control application to
monitor the mixer settings, you will find under the playback tab there
are two volume sliders: Master and PCM. When XEmacs emits a sound, you
can visually see the PCM volume being momentarily increased. (If the
sound is short, a change in the slider position may not happen every
time the sound is played - try it several times).
If you could look into this and repair it, or give me suggestions
on how it can be avoided, I would be thankful.
Well, doggone. This is what I get for trying to get sound working on
Fedora Core 5. I'm the one who stuck you with this horrible behavior,
Randy. I'll try to fix it.
I wrote the code trying to cope with the sound interface's volume
parameter. I thought the mixer was the right way to deal with it.
Apparently not. If any gnomes in the woodwork know how to set the
volume for one particular sound only, please sprinkle your magic pixie
dust on me.
Otherwise, I'll have to resort to reading documentation!
