Big Sur ALC298PluginFix not work anymore #179

Closed jasjang closed 3 years ago

jasjang commented 4 years ago

When I use the fix It always shows

mount_apfs: volume could not be mounted: Permission denied mount: / failed with 66

I've try to mount it. But still the permission deny.

Please help me to fix it.

check out verb stub kext by kns speed https://www.tonymacx86.com/threads/guide-dell-xps-15-9560-4k-touch-1tb-ssd-32gb-ram-100-adobergb.224486/page-9#post-1539760.

there's some steps. i don't know if they're working in new Big Sur but this alternative audio solution has been working since it was released without any updates as far as i know.

You need to follow this guide. In Big Sur you run on a snapshot of the system volume. So you need to live mount the system volume, do your edits (copy ALCPlugFix and hda-verb to ~/livemount/usr/bin/ and set the right permissions), and then create and bless a new snapshot. The daemon lives in the data partition so you can copy it to its rightful place at any moment.

Note that you will need to edit your config.plist to disable the new authenticated root SIP flag before doing any edits. This will enable you to boot from your new, broken-seal snapshot.

I can confirm this worked on my XPS15 9560. My headphones work at full volume. Caveat: doing this deleted my original, sealed snapshot, I don't know why... This might complicate operating system updates, I don't know, I'm waiting for the first one to find out what happens 🙃
