For those coming from analogue amplifiers the irs2092 is a bit of a shift.
Instead of a few tens of kilohertz you are now dealing with up to about 500KHz square waves.
This needs much more care with decoupling and pcb layout.
A nice tight layout with ground planes works best.
The mosfet driver circuit is crucial to getting it right. Right mosfets with right gate resistor or an extra mosfet gate driver like TC4420 with correct gate resistor.
IR do the IRAUDMP7 application note which even gives a pcb layout.
My first attempt at a pcb was a disaster with the 2092 kept resetting on medium volumes. I had to set OC setting to as high as possible to get a decent volume.
I lowered the gate resistor to 4R7 and that helped quite a bit as I was using irfb4227 mosfets which have a large gate charge. A gate driver IC helped a lot especially when I went on to use two pairs of mosfets.
