|Summary||07980: scion: constant background white noise|
Scion (Seibu) has loud white noise in the background from the moment you start the emulation
The game is flagged for imperfect sound,
The Cinematronics clone of Scion does not exhibit this defect.
The regression version for Scion was 0.144 13 Nov 2011.
In 0.143 both sets sound the same.
In 0.144 the parent set only adds this white noise.

I just checked the driver comments:
Background noise in scion (but not scionc). Note that the sound program is
almost identical, except for three patches affecting noise period, noise
channel C enable and channel C volume. So it looks just like a bug in the
original (weird), or some strange form of protection.
If the noise is there in 0.143, then I can't hear it at all. If so it certainly gets louder in 0.144.
Maybe this report should be closed?

I wonder if the patches are intentional, or a bad dump.
Also is channel C used for anything else? maybe it's not routed if the game doesn't need it.
