Audio doesn't work
I follow the giude to install the Catalina 10.15.7, and everything work well except audio. I try to inject layout-id but failed.
My laptop info: cpu: i5-6200u audio: alc-256
I solved the problem by cleaning the nvram. 1.use "nvram -xp" to check the value. 2.use "nvram -d keyname" to remove the value of nvram. 3. inject the layou-id 13. 4. restart
