Glad to hear that Source Relative fixed the artifacts.

For the head-relative sounds ... if 'SourcePosition' and 'ListenerPosition'
are world co-ordinates, then all you need to do is set the AL Source
position to SourcePosition - ListenerPosition.  You can also set the AL
Source Velocity to SourceVelocity - ListenerVelocity (although
SourceVelocity is probably equal to ListenerVelocity).
