hiroo Posted December 7, 2006 Share Posted December 7, 2006 Recently, my system has started this stuttering, crackling sound whenever sound output starts up. For example, if the system is on and working, then I load iTunes and play a song, the first second crackles and stutters a bit, then plays fine after that. if I pause and unpause within about 3 seconds, it will start playing immediately and fine. but if i pause for over 3 seconds, it will have the crackling startup again. This behavior seems to be with any program that outputs audio, such as iTunes, Final Cut, etc. i can't remember when this started, but I worked on a video in Final Cut a couple of weeks ago that had extensive audio work and I don't remember getting so annoyed by it so I don't think it was doing it then. Then this past week I was finishing up a project and the crackling was so bad that it was almost impossible to use given the nature of video editing: play, stop, adjust, play again...most of the time the stop and adjust will be more than 3 sec and then the crackling will cover up the beginning of the playback so you can't tell if what you did was ok or not. I'm using the built in audio on my ASUS P5LD-VM 2.0 with the JAS 10.4.8 Semthex and the Azalia Audio hack. If I had to speculate, I'd guess that somehow the audio chip is powering down or going to sleep mode and then has to come back on. Anybody experience this problem? anywhere I should look for the problem?

hiroo Posted December 7, 2006 Author Share Posted December 7, 2006 here is an audio recording of the problem. there is a crackle right when i start up the music the first time, then i stop/start it quickly to show no glitches under a certain stop time, then as I increase the stop time, it starts crackling on start. any clues? crackle.mp3 Link to comment https://www.insanelymac.com/forum/topic/35188-crackling-whenever-sound-starts-up/#findComment-249859 Share on other sites More sharing options...
lord_muad_dib Posted December 7, 2006 Share Posted December 7, 2006 you're using an old kernel. try a kernel with fsb autodetection or type this at boot prompt fsb=xxx where xxx is your fsb value/4 Link to comment https://www.insanelymac.com/forum/topic/35188-crackling-whenever-sound-starts-up/#findComment-249868 Share on other sites More sharing options...
hiroo Posted December 7, 2006 Author Share Posted December 7, 2006 you're using an old kernel. try a kernel with fsb autodetection or type this at boot prompt fsb=xxx where xxx is your fsb value/4 is there a reason why you think this is the cause of the problem? as for the fsb setting, i previously had a problem with the real-time clock running fast and solved it by putting the fsb setting into a the boot.plist or somewhere, which fixed the clock.

lord_muad_dib Posted December 7, 2006 Share Posted December 7, 2006 so you should be set... strange... try to upgrade to the latest kernel and delete the fsb settings in the boot.plist Link to comment https://www.insanelymac.com/forum/topic/35188-crackling-whenever-sound-starts-up/#findComment-249919 Share on other sites More sharing options...
hiroo Posted December 8, 2006 Author Share Posted December 8, 2006 ok, figured this out finally. the fsb setting was the problem, just not in the expected way. i had the mb set to 10% overclock and had set the fsb accordingly. last week when i was trying to debug this problem during the many blind reboots, i think the overclock turned off so the fsb setting that i had hard coded was inaccurate. you're right that i should update the kernel, just was trying to have a "if it ain't broke don't fix it" philosophy with this system. THanks for the clue in. Link to comment https://www.insanelymac.com/forum/topic/35188-crackling-whenever-sound-starts-up/#findComment-251033 Share on other sites More sharing options...
