Description Reinis Danne 2012-03-03 07:49:32 UTC
If audio volume is adjusted in vlc to lower level than current level in sound applet it doesn't change the volume in applet, but as soon as it is set in vlc to higher volume than currently set in the applet then the volume setting in applet jumps up (not necessary matching the setting in vlc), moreover, both changes add up making the sound volume to skyrocket.

I think a while ago totem had similar inconsistent behavior, but now it is fixed and applet volume settings follow those of the totem media player. Whatever they did apparently it also has to be done for vlc.

Reproducible: Always

Steps to Reproduce:
1. set volume in the applet to e.g. 50%
2. set volume in vlc to e.g. 30%
3. change volume in vlc in range below 50%
4. change it to above 50%
Actual Results:  
Volume in applet doesn't change as long as in vlc it is changed in range below current applet setting (actual sound volume does change), but jumps up if setting in vlc is turned up above the setting in applet.

Expected Results:  
Do one of the two:
- Don't change applet audio volume from vlc at all
- Consistently follow vlc volume in the applet

Comment 1 Alexis Ballier gentoo-dev 2012-03-20 09:29:48 UTC
confirmed here, could you please report it upstream ? ( )

there's not much we can do at gentoo side :(
Comment 2 Tom Wijsman (TomWij) (RETIRED) gentoo-dev 2013-10-26 06:46:29 UTC
You can adjust /etc/pulse/daemon.conf to disable flat-volumes if you want them to be separated from each other; as this solution exists and this bug is rather old, as well as I don't know if this has been reported, I'm closing this for now.
