Description Erik Schilling 2013-08-11 14:47:53 UTC
Description of problem:
If i do not have flat-volumes = no set in the /etc/pulse/daemon.conf 


Version-Release number of selected component (if applicable): 


How reproducible:
Play music in banshee or amarok(via pulseaudio).
Try to change the volume (Low volumes have almost no differences. Then it suddenly becomes REALLY loud).
Then start a flash video or start a game / any application which plays via SDL / anything not using gstreamer?
Try to change the volume again

Actual results:
Before the game or flash video starts the volume is almost impossible to set to a proper (silent) value.
After starting the game or flash video the music in banshee / amarok becomes significantly more silent. And the volume control works like if I would enable leave flat-volumes to the default value (commented out)


Expected results:
Without any need to touch any configuration files the sound of the music players should stay on the same volume and the volume control for the music channel should work in a linear way (like it does for me if i set flat-volumes = no.


Additional info:
I am using headphones.
Packages are all on latest Fedora 19 status (I updated all today).

lspci about audio:
00:09.0 Audio device: NVIDIA Corporation MCP73 High Definition Audio (rev a1)

My headphones are connected via 3.5mm line out


Workaround:
Simply set flat-volumes = no in your /etc/pulse/daemon.conf

Regards,
Erik

I cannot reproduce the behavior you describe.  On my f19 x86_64 box, running amarok (and playing), and watching flash video... I hear both without noticable change in volume.

Do you have a specific example of "any application which plays via SDL / anything not using gstreamer" that I can test with?

Comment 2 Erik Schilling 2013-08-11 17:21:16 UTC
aplay works for reproducing the bug for me.

Screencast of the bug

Screencast where I first run amarok playing a song. Then start aplay. Then stop aplay again. There is no sound in the screencast. But you can see the volume going down in pavucontrol in the background.

Comment 4 Fedora End Of Life 2015-01-09 19:24:29 UTC
This message is a notice that Fedora 19 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 19. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 19 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 5 Fedora End Of Life 2015-02-17 16:42:55 UTC
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
