CPU is Intel(R) Pentium(R) III Mobile CPU 800MHz with 512 MB of RAM I think this is a dupe. Could well be, I thought I heard something, but couldn't find a matching bug :-( My PII 366 128Mb has a constant stutter despite apparently having spare CPU here. Notably esd doesn't have the same problem - and uses 2x orders of magnitude longer buffers to the sound card. Interestingly, gstreamer-properties "Test" signal stutters just as badly as banshee: and it's not (apparently) writing data en-mass to the daemon either. So (apparently) the daemon is quite good at stuttering without outside input ;-) Interestingly the Fedora strace JP sent me also shows these ridiculously tiny fragment sizes:
2661 recvmsg(37, {msg_name(0)=NULL, msg_iov(1)=[{"\0\0\0\10\323W&\271\0\1\3000\0\0\1\364", 16}], msg_controllen=24, {cmsg_len=24, cmsg_level=SOL_SOCKET, cmsg_type=SCM_CREDENTIALS{pid=2831, uid=500, gid=500}}, msg_flags=0}, 0) = 16
eg. so - I guess it's not just us ;-)
As a punt in the dark: I would guess that we should sacrifice all these theoretical nicities of "low-latency" that ~few people cares about for "doesn't click" which annoys ~everyone ;-)
I think your Dell laptop has the ac_97 sound card, so this might be helpful: http://dev.compiz-fusion.org/~wfarr/viewpost?id=22 does it change anything? I was seeing this stuttering sound while switching workspaces very quickly with the keybindings. With this: options snd_intel8x0 ac97_clock=48000 in /etc/modprobe.conf.local, and I can't replicate it anymore, so I guess it really helps. Let's see what Michael says about his very old laptop. Casual, does this fix the issue for you? options snd_intel8x0 ac97_clock=48000 doesn't seem to make much of a difference, I must say that on the Sony Mini-Notebook the whole of 11.0 is rather slowish and as I am testing with Banshee it might also come from influencing the buffering, need to test it with an audio CD as well.. Maybe it would be worth checking just why running 11.0 on a reasonably well equipped Notebook would meet such severe performance issues. I am running Windows XP on Pentium with reasonable results... Doesn't make any difference playing a music CD either ( imported to fixed disk and playing with Banshee ). Try this one. https://bugzilla.novell.com/show_bug.cgi?id=392037 CJP, is the referenced bug in #11 any help? Yes, 392037 seems to be an exact duplicate of this one. The problem is gone for me too, thanks to Blake for pointing it out DUP'ing then *** This bug has been marked as a duplicate of bug 392037 *** |
