I can confirm this bug with kubuntu 8.04, kde 4.1 beta 1, snd-hda-intel, linux 2.6.25.

Possible duplicate of

but as stated a different kde version (4.1 before beta 1?).

with opensuse11.0 and 4.0.82 I can't reproduce it now
Comment 3 dionisus torimens 2008-06-20 12:19:30 UTC
Very well. If you are sure then I guess you should close it for now.
Comment 4 sts 2008-06-21 15:16:53 UTC
seem to work for now
Comment 5 sts 2008-06-27 12:21:10 UTC
no, it's still exist in 4.0.83 :(
Comment 6 Matthias Kretz 2008-07-03 21:26:44 UTC
It's is "fixed" in opensuse 11, yes. But the fix also introduces crashes. The real fix is http://www.kde-apps.org/content/show.php/Phonon+Xine+TNG?content=84411
