Summary	08352: gba [sma and clones, gwatch4 and clones, sonic and clones, bombtour and clones, bublbobl and clones]: Missing audio channel
Description	One of the audio channels seems to be missing in some games, like Game & Watch Gallery Advance/4 or the Mario Bros minigame included in Super Mario Advance (the missing channel is audible in Super Mario Advance 2, 3 and 4, though). Original hardware behavior: MAME 0.244 and earlier: Other games affected by the same bug: -Bomberman Tournament: Intro. -Bubble Bobble Old & New: Game Over in "Old" mode. -Sonic Advance: Second level.
Steps To Reproduce	gwatch4: -Just load the game. sma: -Select the "Mario Bros" game. -Start a game. sonic: -Just wait for the second demo to play. bombtour: -Just wait for the intro sequence to start. bublbobl: -Start a game in "Old" mode. -Get killed. -Wait for the "Game Over" text to show up.

If you could stick to a specific instance and give us a recording of original vs. emulated perhaps something can be done about this. For instance, sound improved as recently as 0.242 which fixed a long standing issue. Sound regressed originally on 0.179 so 0.178 and earlier may have improved sound? Can you compare that to how it is supposed to sound and make some comparison audio recordings?
