            Bug ID: 490633
           Summary: When changing volume rapidly, the feedback sound
                    pops/clicks
    Classification: Plasma
           Product: plasma-pa
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: minor
          Priority: NOR
         Component: general
          Assignee: plasma-b...@kde.org
          Reporter: tempqd...@mailinator.com
                CC: isma...@gmail.com, m...@ratijas.tk
  Target Milestone: ---

SUMMARY
It seems the volume OSD's feedback sound immediately interrupts itself when
re-triggered before the full sound has played. When any audio file's volume
goes instantly to 0 (or a different value), this causes a click/pop noise.

If the sound instead smoothly (but still quickly) faded to 0, there would be no
clicks/pops and it would be much less abrasive to hear, and would be perceived
as much less glitchy.

When the volume down key is *held* (depending on how fast your key repeat rate
is set), there's all kinds of ugly-sounding glitches; maybe there should
additionally be a limit to how rapidly the sound can be played?


STEP TO REPRODUCE
1. Press the volume down (or up) key rapidly, such that the feedback sounds
interrupt each other

OBSERVED RESULT
Clicks and pops are heard

EXPECTED RESULT
No clicks or pops are heard


OS: openSUSE Krypton (today's git master)
