i have update to lion 7.2 and no sound
installed apple hda rollback and realtek extension and no sound too
problem please help!!!!
Ok i sorted my sounds fella, i'm not saying this is the right approach but it appears to have worked for me.
Have a read on the following link
http://www.tonymacx86.com/viewtopic.php?f=16&t=19468
My initial install was done using the DSDT for the MOBO but i done the following :-
As the above mentioned post suggested i removed a number of the *.kext files
/System/Library/Extensions/AppleHDA.kext
/System/Library/Extensions/HDAEnabler*.kext (yes, all of them)
/System/Library/Extensions/VoodooHDA.kext
/Extra/Extensions/LegacyHDA.kext
/Extra/Extensions/ALC8xxxHDA.kext
Once these were removed i ran the MultiBeast with just 'System Utilities' selected and then rebooted the machine, as the post suggests the audio card was removed from the System Profiler.
Once rebooted i then ran MultiBeast again selecting the 'UserDSDT Install', 'System Utilities' and as the link above suggests the following from the 'Drivers & Bootloaders' section
Code:
Drivers & Bootloaders
+ Kexts & Enablers
+ Audio
+ Realtek ALC8xx
+ ALC8xxHDA
AppleHDA Rollback
+ Non-DSDT HDAEnabler
+ ALC889
As others will point out i'm not sure the ACL889 is needed as it's under 'Non-DSDT HDAEnabler' but it worked for me.
Good luck
