Hello everyone, I have a sound problem after installing catalina beta on my dell E7240. (same as Dell E7440) Everything works except sound and bluetooth. I would like if possible to solve the problem of sound first. I tried to add the kext AppleHDA_ALC292.kext in L/E, or to copy paste S / L / E AppleHDA.kext from High Sierra to S / L / E Catalina and it's still not working. After each change, I dumped kext cache and repaired partitions. Thank you to the person who will help me.
