Super Mario World sound issues

[TheHeggy]

Is it just me, or do some of the sounds in Super Mario World not sound right? The sound as you're going down a pipe or when you hit a mushroom, or shoot fireballs. Everything else sounds perfect except for those couple sounds.

This is the case across multiple roms I've obtained from multiple sources.

Any ideas?

Use ZSNES.
Sound is perfect.
