Description Daniel Duris 2012-07-09 15:00:26 UTC

HDMI volume (I haven't tested for stereo jack output) randomly jumps (changes, fluctules) while music is playing. Song volume is suddenly randomly decreased or increased, sometimes even falling silent for tenth of a second.

Reproducible: Always

Steps to Reproduce:
1. play music
2. listen to the song
3. volume randomly changes
Actual Results:  
volume fluctulation

Expected Results:  
volume steady

I have tested disabling kmix, trying veromix instead, i have reinstalled alsa, pulse audio, gstreamer, kde.

alsamixer or pulseaudio don't show changes in volume as far as I can see.

Unmaintained version - let us know if it happens with more current versions.
