Summary	07714: gauntleg: Missing streaming BGM/Sounds during gameplay
Description	Bug 05636 fixed this issue in 0.155. But, in 0.222, the bug has returned. Might have broken again in any version between 0.156 and 0.222. Music and sound seem to be present up until you start the the first level at the Mountain. At that point the music and most sound effects seem to disappear and it is not updated. By the end of the stage, sound effects return during score tally and for the next level.
Steps To Reproduce	Select Mountain kingdom Play about 30 seconds Observe announcer stops speaking, no more combat sounds

Adjust the volume and it seems to work until you reboot again. This doesn't appear to be like the same issue as before and appears tied to nvram settings for some reason.
No.17862 Hydreigon Tester Jul 31, 2020, 23:33	Some games have some sound timing issues playing sounds/music at incorrect places. In warfa, the menu music will continue to play into the first cutscene and ingame, gunshot sound effects sometimes wouldn't play. Possible ADSP related timing bug?
