Bug ID: 380857
Summary: Respect playback device output on systems with
pulseaudio (flat-volumes = yes)
Product: kde
Version: unspecified
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: leon...@lausen.nl
Target Milestone: ---
flat-volumes, which is enabled by default in PulseAudio (though many
distributions disable it) scales the device-volume with the volume of the
"loudest" application. Applications, unaware of this feature, can set their
volume to 100% at startup, potentially blowing the speakers or ears of the
user.
Unfortunately KDE applications do exactly that, which is not only a health
hazard for users but also relatively hard to debug for users unfamiliar with
PulseAudio.
KDE Applications should therefore at startup never set their output volume to
100%, but simply to the volume of the playback device to which they are
outputting.
I noticed this behaviour in particular with the error messages generated by
Dolphin and Okular, but it probably affects more applications.
