sb400 AC97 kexts made by Slice: AppleAC97Audio.kext
Manufacturer ID: 0x1002
Product ID: 0x4370
it works, once again, proof of good work from Slice!
AppleAC97AudioATIIXP works even for Leo 10.5.2 (Kalyway 10.5.2 to be precise)
I recommend those archived plugins to be included into Kalyway delivered pack: AppleAC97Audio.kext (note to kalyway)
side effect: hardware volume control button Up/Down have sticky effect yet fixed - once pressed doesn't change volume level by 1, instead staying in changing mode as if it would be holded, until system restart. This hope will be fixed (once source code of following kext plugins will be published by Slice)
Im running Leo 10.5.6 and also installed this kext to make it work with my 0x4370, works fine!
But, has the same issues with buttons declared up there,
is still there a fix to this issue?
Also the mute button light is turned on itself 'til a sound comes to play.
I hope we can fix this issues soon!
