draskostar Posted April 3, 2021 Share Posted April 3, 2021 Anyone having a issue with static noise with headphones on m6800? I am on latest big sur, 11.2.3. In case of wired headphones (jack) there is no sound at all, only noise is coming out. With wireless headphones (bluetooth) is better but sound is stuttering. What I tried till now: - AppleALC is must have for working sound (internal speakers no problem at all) - put Codeccommander into L/E did not fix the problem (repaired permission and rebuilt cache didn't help, still noise) - I found fix on the internet - jack fix and hda-verb in bin folder together with Codeccommander in S/L/E but I can't confirm that one. After I get access to root files I did all of this but I can't boot into the system anymore. I am stuck with Apple logo. I will probably need to reinstall big sur again. Below are instructions that I used to enable write acces. How can I fix boot problem? Please help Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 3, 2021 Moderators Share Posted April 3, 2021 It's a bad idea to install to /S/L/E Follow the post installation instruction from here for Alc_fix. Known issue for ALC292, so this fix will work on your system too. You might have to disable SIP, and enable write access. Link to comment Share on other sites More sharing options...
draskostar Posted April 4, 2021 Author Share Posted April 4, 2021 Thanks Jake for instructions. You're right I have to enable write access but till now I was not successful. I am on latest big sur 11.2.3. Can you please send me some instructions how to do it. What I have found on the internet wasn't working for me. Thank you in advance Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted April 4, 2021 Moderators Share Posted April 4, 2021 did you boot to Recovery Mode Disable SIP first? csrutil disable and run this in terminal after reboot from recovery mode csrutil status //to confirm if SIP is disabled sudo mount -uw / sudo killall Finder sudo spctl --master-disable //only need to be ran once cd ~/Downloads/alc_fix //assuming it's in download folder ./install Link to comment Share on other sites More sharing options...
draskostar Posted April 5, 2021 Author Share Posted April 5, 2021 csrutil was disabled all the time via config (FF0F0000) what helped for me was I went to usr-local and create bin folder. After that I put manually inside ALCPlugFix and hda-verb, restart a PC and wired headphones now work perfectly 1. usr-local-bin -> ALCPluxFix and had-verb 2. EFI boot-OC-kexts -> codeccommander -------- wireless headphones still have this stuttering sound which is related probably to bluetooth functionality (AC 7260). I found out If headphones are near PC sound is OK but immediately when distancing from PC sound is stuttering again Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 5, 2021 Moderators Share Posted April 5, 2021 Yeah, Intel wifi/ BT is still Beta. Switch to Broadcom or use a real card with adapter for better support Link to comment Share on other sites More sharing options...
