Summary	09006: timeplt and clones: Sound mixing issues (and possible missing lowpass filter?)
Description	In MAME, the explosion sounds are much louder than everything else, on a PCB they are quieter and the music and firing sounds are louder. Also it seems like the explosion sounds use a Scramble-like low-pass filter that's not emulated in MAME.
Steps To Reproduce	Start a game with sound enabled.
