Audio problems I faced and fixed
iztec, jetpr : I made every mistake as far as audio is concerned but now it is all good. Here is some stuff:
(a) Use the the DSDT update posted by brfransen,
(b) Update the extensions.mkext under /Extra. It may be that the LegacyALC883.kext is not being picked up. Look for a posting by me, infinitethanks, for a long way to do it and responses by smarter people to my posting for a short way to do it.
(b) Use option, system profiler to check the audio profile. If it is not available, you may not have set the audio to auto in bios.
(c) when everything is set correctly, my audio profile looks like the following:
Device ID: 0x1458A002
Audio ID: 883
Available Devices:
