lagloose Posted May 26, 2014 Share Posted May 26, 2014 Hi there, while trying to get rid of that awful audo crackling with Voodoohda i tried nearly everything which can be found in the different forums. No succes at all. I have the effect (which obviously many people have....) that i have crackling sound. But it get's clear as soon as i move the mouse or touch the touchpad. So i decided to try a fresh installation. There i noticed that in the well known startup screen where all those 'Welcome' messages in a lot of different languages appear, they 'stutter' from right to left. But than again, as soon as i move the mouse or touch my pad the messages move flawlessly with out any stutter.So perhaps this is hint for the more experienced Hackintosh people out there, how it perhaps can be fixed. I guess they could make a lot of people very happy.... :-) I'm on Linux ATM. So here's a 'lspci' dump of my Samsung E257 Nano Notebook. --- 00:00.0 Host bridge: Advanced Micro Devices, Inc.

Gringo Vermelho Posted May 26, 2014 Share Posted May 26, 2014 Look here for some tips: http://www.insanelymac.com/forum/topic/104797-creative-sb-live-audigy-audigy2-emu10kx-edsps-osx-driver-info-here/page-41?do=findComment&comment=2018998 Obviously there's not much you can do regarding power management since you can never have it working natively. Something that you can do is make sure that your bus ratio is correct: http://www.insanelymac.com/forum/topic/240542-guide-getting-your-busratio/ Link to comment Share on other sites More sharing options...
lagloose Posted May 27, 2014 Author Share Posted May 27, 2014 Hey, thanx for replying... I already checked my busratio respectively fsb. Started my machine with 'fsb=200' bootoption and dmesg/bdmesg exactly reports 2 cores running at 2.1 Ghz which is absolutely correct. Why do you think the problem is in the power management ? My guess is, that this is kind of an IRQ problem. Perhaps it has something to do with Voodoo PS2. Unfortunately there are no bios settings where i could change IRQ's... However, i bought a cheap USB Soundcard for 5 bucks and this worked out of the box without any problems. But due to the fact that i don't want to carry around external speakers and a stick every time, it would be great to have internal audio working...

Onixs Posted May 27, 2014 Share Posted May 27, 2014 Im not sure if this helps... iiirc, there was a flag that i used long time ago (i cant recall which {censored} P4 laptop it was) called "idlehalt=0" to solve my audio crackling. But i am not very sure if this flag works on vanilla kernel since i have used legacy before. ( maybe Gringo could answer that) Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted May 27, 2014 Share Posted May 27, 2014 I don't know either, but it's an AMD PC, so no vanilla kernel. He could just try it and see if it does anything. The worst that could happen is that nothing happens... Link to comment Share on other sites More sharing options...
lagloose Posted June 6, 2014 Author Share Posted June 6, 2014 ...and that is what happened. Unfortunately nothing :-) :-( This is really a strange kind of behaviour and i have no ideas anymore how this could be solved. What's really working is the 'yes > /dev/null' workaround. This gives even clear sound with Garageband. But this is of course neither a solution nor an 'acceptable' workaround for this problem. Would be interesting to know what the 'yes' command does (Is the sourcecode for 'yes' available ?) Link to comment Share on other sites More sharing options...

lagloose Posted June 24, 2014 Author Share Posted June 24, 2014 Seriously... the source code is available here and ready for discussion: http://ubuntuforums.org/showthread.php?t=1159384 It also includes no.. and more.. ...But I do not know if you can solve the problems of sound The problem with stuttering/crackling audio really drives me nuts and is very frustrating. Meanwhile i've discovered that in most cases the 'stuttering but not stuttering when moving the mouse' problem is not audio-specific. It seems to be a general (kernel ?) problem on some AMD machines. You can watch this (at least here..) also, when you have floating text. IE if you have installed HWMonitor, open 'About HWMonitor', watch stuttering in floating text and than move the mouse (or touch trackpad)... I also found out what the 'yes' proggy does. It simply does this: --- int main(argc, argv) int argc; char **argv; { if (argc > 1) for(; (void)puts(argv[1]); else for (; (void)puts("y"); } --- 'yes' is part of the OSX shell_cmds package which can be found here http://opensource.apple.com/tarballs/shell_cmds/ in different versions. Stuttering also disappears when you have network activity i.e. when utorrent is down/uploading. It seems that 'cpu activity' in general does remove stuttering/crackling. But i have no idea where or how this can be fixed. Is it an IRQ problem ?, is it related to power management ?... No idea. Link to comment Share on other sites More sharing options...
