Description Will Woods 2009-04-20 19:19:13 UTC

pulseaudio-0.9.15-10.fc11.x86_64
gstreamer-0.10.22-3.fc11.x86_64
rhythmbox-0.12.0-5.fc11.x86_64

Here's the scenario:
0. Enable Rhythmbox crossfading backend, set rb volume to 50%, close rhythmbox
1. Desktop quiet, gnome-volume-control-applet shows volume at 55%
2. Start rhythmbox - rb's volume control reads 50%
3. Press play
4. g-v-c-a jumps to 93%. OW THIS IS REALLY LOUD.
5. Quickly adjust g-v-c-a to 50%.
[Time passes]
6. Pause song.
7. Press play. Volume jumps to 93% again (goto 4).

You can also cause the volume jump by clicking on rhythmbox's volume control button. 

Volume does *not* jump unexpectedly when the crossfading backend is disabled.

Comment 1 Will Woods 2009-04-20 19:44:30 UTC

The second case - volume jumps when using the volume control in rhythmbox - still happens if the crossfade backend is disabled. Alas.

Also, please note that the rb volume control has to be *changed* - moved up or down - to trigger the problem.

Comment 2 Bastien Nocera 2009-04-22 12:42:24 UTC

Should be fixed in 0.12.0.92, could you please test before I try to get this version tagged?

Comment 3 Will Woods 2009-04-22 14:31:42 UTC

Confirmed - this build fixes the volume jumps when hitting play/pause while using the crossfade plugin.

(The volume still jumps around when I use the rb volume control, but I suppose that's a different bug.)

I'm not as irate as I used to be.

BUT THIS IS A **!*!&!&! HEALTH HAZARD, and seems to be present in my fedora 11 rhythmbox.

THIS IS UNACCEPTABLE.

I seriously think I may have permanently damanged my hearing because of this.

Not as much as the GNR+metallica concert I went to back in '93.  But that was a willing choice.  Seriously, there need to be measures taken to prevent ANYTHING like this bug from ever happening again, presumably in alsa/pulse.

This bug needs to be reopened and assigned to F11 NOW.

(I have a track record of making loud comments that turn out to be some problem with my environment.  I consider this a serious enough issue that I don't care about getting egg on my face if I'm wrong)

At least put a comment in the bug explaining how to reset gconf, reinstall whatever, blow away whatever file to undo this.
