amarok: breaks under pressure

When there is a high cpu load, amarok  starts skipping, and sometimes it skips 20 seconds of the song... This never happened with BMP.  It does the same with both the gstreamer and arts engine.  Any ideas?  Does this happen to anyone else?

I'm using kde btw.

Re: amarok: breaks under pressure

what kernel do you use? (what scheduler?)

i listen to music (ogg's) and compile kernel at the same time and no problem with skipping (using arts) [cpu is running 100% over 2 hours]

Re: amarok: breaks under pressure

My experience with amaroK 1.0 CVS version (I had a problem and built it myself) - output engines
1. gStreamer (alsasink) = ~38% CPU usage
2. gStreamer (osssink) = ~10% CPU usage
3. xine = ~6% CPU usage
4. switching back to the previous version I found out that arts uses also ~6% (I couldn't find the arts engine in the CVS version)

P.S. I'm using arts in KDE with real-time priority, one more reason for not to feel any interruptions during playback (when compiling for example).

I'm currently using the xine output plugin (using a CVS snapshot). I've tried researching on the CPU usage problem but I came to the conclusion something might be wrong with my gStreamer (btw, the package is flagged out-of-date) (mp3 codec problem) or with my ALSA drivers. I haven't tested with oggs.

I'm using kernel 2.6.7-ck7 (I've built it some time ago but didn't test its responsiveness - I have several kernels installed for testing)

is this implemented?
(i also do not get crossfade using gstreamer, but as i use arts standard, i don't have the need to - maybe you can try email the author of amarok about gstreamer-crossfade issue )
