This seems to be a glitch in recent versions of phonon-backend-gstreamer-0_10.

I had this happening with kpat 3.6 on openSuSE 12.1 (64 Bit, kernel 3.1.9-1.4-desktop), KDE 4.7.4 "release 5" after updating to phonon-backend-gstreamer-0_10-4.5.90-5.7.1.

After "downgrading" to phonon-backend-gstreamer-0_10-4.5.1-5.6.1, everything is fine again.

Workaround (downgrade) solved that issue for me!

Thanks Matthias!
Comment 4 Parker Coates 2012-02-21 02:58:35 UTC 
I just ported KPat from Phonon to KgSound, which uses OpenAL internally. As OpenAL is designed for low-latency audio, such delays and freezes should be gone.

Thanks :-)
Comment 6 Christoph Feck 2012-02-22 12:46:03 UTC 
Parker, the same issue is present in kshisen, see bug 289473. Does it need to be ported separately, or is the fix actually in libkdegames?
Comment 7 Parker Coates 2012-02-22 15:43:48 UTC 
It will need to be ported separately, but like KPat, the port should be very easy. I'm sure Frederik will have it done in time for SC4.9. If not, I can probably do it.

Comment 11 Pavel 2012-06-13 08:22:26 UTC 
have the same bug in Kubuntu 12.04. Why is the bug marked as SOLVED? Where's the solution of the problem?
Comment 12 Frederik Schwarzer 2012-06-13 10:15:17 UTC 
It is marked as "Fixed in: SC4.9" as seen in the upper right column.
So the fix will be available in KDE 4.9.
