Hi all,
I installed MacOsx Big Sur with Opencore on my Dell XPS 13, all is working except sound on internal speakers.
Kext used are Lilu and Applealc .
My card is an ALC299, I configured boot-args with these arguments (alcid 21 and 22)
-v keepsyms=1 swd_panic=1 debug=0x100 alcid=22 alcdelay=1000
Input Sound and output across Bluetooth device (or Airplay) are working, but nothing on internal speakers (working in Windows).
Anyone can help ?
Thanks.
