Roxasss Posted October 30, 2014 Share Posted October 30, 2014 btw my first post so sorry if this is not perfect so, my acer 4738 got no compatible applehda (at least yet)so in the mean time i use voodoohda which is keep crackle after couple of minutes and to fix it i must manually refresh the audio format in MIDI to make it better (repeatedly) yesterday i got an idea from some comments in a post that said maybe we can automatically refresh the audio format from terminalso i search it in the internet and manage to make some terminal command that did the jobhere it is:sudo killall coreaudiod just type it in terminal and your audio will be good as new and then i read in some website there is a comment that can repeat a command in some interval it is called "watch" ,but you need to disable password in sudo command because with pass in sudo the loop will stop to ask for pass input.here is the way to install watch : instal watch : We are using “curl” a command line “broswer”"curl -O http://ktwit.net/code/watch-0.2-macosx/watch"(copy to terminal without quotes) Make “watch” executableBy doing this we tell Mac OS that this is a program that can runchmod +x watch Test the programLet’s make sure everything is in working order../watch Install “watch”Optional: By following this next step we are placing watch into a system location that will allow you to run it from any location in the Terminal (You will be prompted for your password)sudo mv watch /usr/local/bin/ Congrats, you have added the watch command to your Mac OS X System. here the way to disable sudo pass first show hidden file with this command in terminal : defaults write com.apple.finder AppleShowAllFiles YES and then follow this https://romkey.com/2...rd-on-your-mac/ and here if you don't know how to login as root http://support.apple.com/kb/PH14281and after making the pass logout and login as other with the name "root" and the root is your root pass after you finish making password-less sudo here the command watch -n 900 sudo killall coreaudiod ==> comand automatic every period of interval 900 is interval = 900s sorry if my english not that perfecti'm just typing without thinking the grammar (Asian ^^) btw any1 is welcomed to help me making some script to make it run at star up 1 Link to comment Share on other sites More sharing options...

shrieken213 Posted May 14, 2015 Share Posted May 14, 2015 I have this exact problem in 10.10.3, except it lasts 1 second before desyncing. VOX does work, but VOX can't change bitrate fast enough. I have 2 0.5-second silent WAVs of 44.1/48kHz on a looping playlist. And after a while even VOX method stops working... Link to comment Share on other sites More sharing options...
everart Posted August 19, 2016 Share Posted August 19, 2016 I have exactly the same problem with the same acer 4739!!! And I just find out that the problem is with IOAudioFamily.kext. You need replace with this one Don't use AppleHDA use the last voodoohda 2.8.8 and if you have the same codec as me you can try my info.plist here IOAudioFamily.kext.zip patche para minha placa Info.plist.zip Link to comment Share on other sites More sharing options...
