[Unity] Potential Optimizations in SteamAudioSource

[Kulgann]

I noticed that in the Update() of SteamAudioSource the parameters are updated every frame regardless of whether there was a change to them. The individual cost is minuscule but with enough sources in the scene it can add up

Is there a reason that the params are being updated like this every frame or would it be okay to refactor the code so that the params are only updated when dirty ?
