INDY3: Rare assertion in AdLib player

Reported by:	eriktorbjorn	Owned by:	lordhoto
Priority:	normal	Component:	Engine: SCUMM

Description

Current Git snapshot, English VGA version of the game.

Very occasionally, the new AdLib player will trip the following assertion when Indy changes clothes after climing out a window in Castle Brunwald:

scummvm: engines/scumm/players/player_ad.cpp:324: void Scumm::Player_AD::freeHWChannel(int): Assertion `_hwChannels[channel].allocated' failed.

It happened the first time I tried it, but I don't know how many times I had to try for it to happen a second time, let alone a third when I finally tried it in GDB. I can only assume it is some interaction between the music and the random (?) sound effects. Anyway, here is the backtrace I finally got:
