Hi, the quoted post seems to be talking about 2 different issues:
1. Sound volume not saving across reboots, and
2. Volume slider icon not in sync with actual system volume.
Which are we talking about?
It was either on this thread or on another thread here on TMX that I saw something about a fix for just that problem (volume slider sync). Have you guys tried searching the forum?
As for audio volume saving across restarts, not sure if it's a codec thing or if it might possibly be NVRAM. Of course
@RehabMan would be the one to clarify all of this, but I'd start by making sure that NVRAM is working.
Either use EMUVariable *with RC Scripts* or use AptioMemoryFix. Don't use both EMUVariable and AptioMemoryFix, and neither use EMUVariable without the clover RC Scripts...
Again, my basis for this is that I believe I read that volume is saved on NVRAM, of course I could be wrong, but in either case, working NVRAM is never a bad thing lol.
HTH
