Breaking bricks doesn't always make sound in Super Mario Land, plus other audio issues

[goodstuff626]

Breaking bricks doesn't always make sound in Super Mario Land. Tried different emulation & audio settings, and it will still be silent sometimes when breaking bricks. Also using super game boy with ntsc region, super mario land (world) has very bad choppy sounding audio, but using super game boy 2 fixes the audio. Are these emulator bugs, or why are these problems happening?

Could you provide more elaborate instructions, or perhaps a video recording, of the bricks issue? I can't seem to reproduce it.

As for audio being choppy on NTSC SGB – which version and frontend of SameBoy are you using, as well as what operating system are you using? If you're using the SDL version, what do the "preferred" and "active" audio driver options say under Audio Options?
