Bug ID: 445523
Summary: lfe sound not working for 5.1 or 7.1 multichannel
audio
Product: plasma-pa
Version: 5.23.3
Platform: Debian unstable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: now...@gmail.com
Reporter: wothum...@gmx.de
CC: plasma-b...@kde.org
Target Milestone: ---
SUMMARY
Line 373 of .../src/kcm/package/contents/ui/main.qml reads:
373: onClicked: tester.testChannel(modelData === "lfe" ? "rear-center" :
modelData)
This has no effect. Although "audio-channel-rear-center.oga" exists within
freedesktop,
its sound is redirected to a nonexistent 5.1 (or 7.1) surround channel (and not
to lfe) by libcanberra
(due to use of CA_PROP_CANBERRA_FORCE_CHANNEL I guess).
In order to fix this I suggest to replace line 373 by
onClicked: tester.testChannel(modelData === "lfe" ? "lfe" : modelData) or even
onClicked: tester.testChannel(modelData)
and link audio-channel-lfe.oga to file audio-channel-rear-center.oga:
../sounds/freedesktop/stereo/audio-channel-lfe.oga ->
../sounds/freedesktop/stereo/audio-channel-rear-center.oga
STEPS TO REPRODUCE
see above
OBSERVED RESULT
subwoofer button not working for 5.1 or 7.1 multichannel audio.
EXPECTED RESULT
plays rear-center audio sound.
