Version: 1.3.2 (using KDE KDE 3.3.2) Installed from: RedHat RPMs OS: Linux When i play an ogg vorbis file (Malcolm Arnold - Fantasy, op. 86 for bassoon.ogg) arts start to "jump" on low notes. the sound comes in stabs. When i play the same song encoded to mp3 (192kbps, and another 224kbps) i don't have that problem. When i switch soundsystem to gstreamer with alsaoutput, i dont have that problem. It is only on low notes ihave the problem. all arts output behave like this with vorbis files. this is quite annoying.
I can confirm this. It also happens on Debian sarge (Linux 2.6.8 on AMD Athlon), package arts-1.3.2-2 It might be reproducible if you have the cd 'Moon Safari' by Air. On my machine, the following steps consistently reproduce the bug: - rip track 2 'Sexy Boy' using cdparanoia. - encode wav using oggenc with all defaults. - play ogg in amarok with arts-engine, or in juk. - the first few seconds (which do, indeed, consist of low-pitched sound) are heavily distorted. To check that it is an ARTS problem, I did the following: - check that cdparanoia reports no unrepaired errors. - play wav on any player, arts or otherwise: no problems. - play the ogg using 'play': no problems. - play on amarok using gstreamer- or xine-engine: no problems. Most other OGGs play perfectly well over ARTS on my box, only this one doesn't. Regards, Rob Hagemans
I had severe problems with ogg playback in KDE. Recently i encoded some files with highest quality. I noticed that the problems were now much worse! When I play the file with artsplay, it sounded horrible (same with any media player in KDE). Then I played it with "artsdsp ogg123 -d oss <filename>" and it worked flawlessly, so I know the file is not broken, arts is. Can anyone else confirm that the problem is worse with high quality?
I can confirm this. The file I encoded first (the bassoon monolouge) was encoded in quality 7 (~224Kbps), and when I encoded it in quality 5, it didn't lag as much.
I think I have found a workaround for this bug. I changed the soundbuffer size from max to 487 ms, 21 fragments with 4096 bytes. The sound is good with this setting (See bug 61081.) Which sound driver do you use? (I use snd_intel8x0.)
Arts is no longer developed and has been unmaintained for quite some time - more than 2 years. With phonon as the replacement for arts in KDE4, we're closing out all the arts bugs in Bugzilla since there is no chance of them being fixed. Thanks
