Comment 1 dionisus torimens 2008-06-08 10:44:38 UTC

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

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

Comment 2 sts 2008-06-20 10:53:36 UTC

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
