[Solved] - Dell XPS 13 9365 2 in 1, audio card present, sound ok with bluetooth device but not on internal speakers


Recommended Posts

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 ?
