Try EC reset (use search).
My laptop doesn't have a removable battery the artifacts come when open the "preferences" from Apple icon, for example.
Test sleep with Apple->Sleep first. Be aware of ~20 sec delay in Mavericks.

Use search, there are many examples of how to do it here (call _OFF() from _INI in the SSDT with your discrete graphics code).

Audio: Best result with patched AppleHDA. Google 'patch AppleHDA guide'. Search for suitable AppleHDA or patch it yourself. Apply appropriate DSDT patches.
DSDT patches you need for AppleHDA: https://github.com/RehabMan/Laptop-DSDT-Patch
Apply: "Audio Layout 12" (change layout-id from 12 to the layout-id used by the patched AppleHDA)
Apply: "IRQ Fix"
I've patched the AppleHDA and now has native sound
