Does this happen with DSP LLE?

Thank you! Loud POP doesn't occur when the DSP HLE is set to "off"!

Thanks. Ideally it should be fixed for HLE as well since HLE is much faster than LLE, but it's good to know that LLE behaves correctly here.

The pop is a single non-zero value (0x0B000000) in the memory read by AXUCode::SetOppositeLR(). Don't know where it's coming from yet.

The game seems to be trying to set the pred_scale field but ends up using a invalid index of -1, indexing the voices out-of-bounds.
