SHERLOCK: Workaround for bad doorbell sound in Serrated Scalpel

Browse Source 
The sound of the doorbell at Lord Brumwell's mansion is played at 1100
Hz. That has to be an error in the game data. The other sound effects I
checked were usually 11000 Hz, and sometimes 22000 Hz. It's hard to tell
by ear which one is correct here, but 11000 Hz seems to match the 3DO
version quite well.

This bug is present in the original DOS version, though less noticeably
so. Perhaps the original audio driver clamps the sample rate to a
reasonable interval? It still gets it wrong, but not as badly?

This fixes bug #10838.
