Jaco Posted April 16, 2007 Share Posted April 16, 2007 Hi. Sound worked fine before 10.4.9 upgrade - then after upgrade (Jas 10.4.9) DVD playback and sound was very shaky and jiggidy, then I add fsb=167 to then kernel parameters in Boot.plist. After that video is smooth again and sound is almost fixed, still a slight pop every few seconds. In about Mac it reflect my processor speed of 2.0ghz which is correct, before the change in Boot.plist it showed up as 2.4 Ghz. Only running with one core though (Cpus=1) Any ideas to fix the poping sound?

Colonel Ingus Posted April 17, 2007 Share Posted April 17, 2007 Any ideas to fix the poping sound? When exactly, do you hear the popping sounds?

Jaco Posted April 17, 2007 Author Share Posted April 17, 2007 I heard it when I played any movies or music files - soft poping sound. But it's all fixed now with the new Netkas kernel that auto-detect the FSB speed - that was the problem in the first place, I guess if I played with the settings for the speeds a bit I could have fixed it without kernel upgrade but this was so easy to do anyway.

Jaco Posted April 19, 2007 Author Share Posted April 19, 2007 If you talking about version 8.9.1 yes that will be the same, but does it say Netkas as well uname -a Darwin jakes-computer.local 8.9.1 Darwin Kernel Version 8.9.1: Thu Mar 26 20:55:00 PST 2007; netkas: 792.18.15~1/RELEASE_I386 i386 i386 Yes the FSB has a lot to do with it, you need to know what your bus speed is and devide by 4 and add that as a kernel parameter fsb=167 for a 667 ghz bus, 200 if you have an 800 ghz bus. That is suppose to work in theory but I still had the slight popping sound. Before that I think the default was 200 and my DVD and video playback stuttered, rest seemed fine and it reported my CPU wrong as 2.4ghz instead of 2.0 ghz The Netkas kernel autodetect the fsb so you don't have to mess with the fsb speed - was easy to install and fixed the problem for me.
