JuK skips, XMMS (and other audio) doesn't

wilburpan · l33t Joined: 21 Jan 2003 Posts: 977

I've been playing around with JuK, but I'm finding that I hear a lot of very brief skips in mp3's I'm playing through JuK. This does not happen with XMMS or with other programs that play audio (mplayer, for example).

One other annoying think with JuK is that for some mp3's there is a brief sound of gibberish audio at the beginning of the track, as if someone was listening to a tape played at a very high speed. Again, this does not seem to happen with XMMS.

Any ideas why this might be happening?

are you using kernel 2.6? juk skipped sometimes for me before I upgraded to 2.6

If you are using 2.6, try the cfq scheduler.

I had a problem similar to this however it also affected kaboodle and noatun, I am using 2.6 and found the problem to be with my IDE drivers(dma was not enabled and I was unable to turn it on using hdparm), I had compiled them as modules so went back and built them in to the kernel and all my problems have now gone, sound is rock steady in any audio app I use.

Hope this helps

I am running a 2.6 kernel with cfq, and dma is set correctly on my machine. My IDE drivers are built into my kernel.

I did check out kaboodle and noatun, and I do get similar problems with these two programs as well.

Same here. I think it's arts related, however, this post have been around for a while, did you get a solution?

try to recompile kdelibs, kdemultimedia and arts with +alsa set in you USE flag. the go to kde control panel -> sound and multimedia -> sound system and set audio device to Advanced linux sound architechture.

that worked for me.

if your speakers starts to make noise after that. just open your kde mixer (kmix) and disable the Surround down mix

I found a workaround for me at least. I changed artsd to use OSS instead of alsa and this got rid of the sound cut-outs in kaboodle. By the way I do use alsa with oss-emulation.

you could try using gstreamer instead of arts. put gstreamer in your USE and remerge kdemultimedia. the in Juk go to Settings->Output to->gstreamer. I've never ahd any skips with it and you can search in flac files too.

oops, i forgot you have to have the kde gstreamer bindings installed first. go to https://bugs.gentoo.org/show_bug.cgi?id=43417 and use that ebuild (kgst-0.6.1.ebuild) to merge the kde gstreamer bindings and then remerge kdemultimedia and it should work.

I don't know if you tried that yet but just lower the ARTS buffer to the lowest possible and try it again.
Control Center -> Sound System -> General -> Skip Prevention

I know that it would be logical to increase the buffer to get better skipping protection (as the name states) but this just worked for me.

Just give it a try.

this is one of the reasons why i don't like using kde. arts really does suck. I've tried everything, and while I can make it better, I still get skips, which annoy the hell out of me.

PowerFactor,

Mind if I asked how you got this working? I've emerged the kgst package from bugs.gentoo.org, I have Gstreamer-0.8.1 installed, and gst-plugins-flac. I compiled everything with flac as one of my use flags. However, I get this error when I start to re-compile kdemultimedia...

PowerFactor · Posted: Wed Jun 02, 2004 8:45 am Post subject:

kgst will not currently build against gstreamer-0.8. I used gstreamer-0.6.4 since that's the only pre-0.8 version in portage.

Hey Powerfactor,

Thanks for the very quick reply! I unmerged kgst, gstreamer-plugins, and gstreamer then installed gstreamer-0.6.4, gst-plugins-flac-0.6.4, and kgst-0.6.1. Kgst didn't want to compile this time and exited with an error,

[code]!!! ERROR: media-libs/kgst-0.6.1 failed.
!!! Function kde_src_compile, Line 129, Exitcode 2
!!! died running emake, kde_src_compile:make

I've spent about 5 hours too long on this tonight and will have to pick up on it later. Gotta sleep sometime! Hopefully, the ebuild maintainers get the bugs worked out soon. It appears that there are already bug reports out there so I don't have to submit a new one.

Cheers!

Sorry, momentarily forgot about that. There is some syntax in a couple of the gstreamer headers that g++ doesn't like. I did file a bug about it. But here's what you have to do

Remove the comma from the end of line 53 in /usr/include/gstreamer-0.6/gst/control/dparammanager.h and remove the comma from the end of line 62 in /usr/include/gstreamer-0.6/gst/control/dparam.h.

Then kgst should compile cleanly.

Thanks PowerFactor! I'll give it a try tonight!
