Let me check the state management to see if hasItemInTray is being set correctly:

The logic looks correct. Let me add debug logs to see what's happening:

I've added debug logs to track the state changes. The logs will show in the browser console when you dispense a product and when the tray renders. Check the console to see if hasItemInTray is being set to true and if dispensedProduct has the correct product object. This will help us identify if it's a state management issue or a rendering problem.

Now I'll create the sound utility and integrate it into the vending machine with screen shake effects. Let me first create the sound utility file:

Now I'll update the main component to integrate sounds, remove debug logs, and add screen shake:

Now I need to add screen shake to the main machine container and add powerup sound to pickup:

Now I need to find the pickup tray section and add the powerup sound:

I've successfully integrated the SNES arcade sound system with Web Audio API. The vending machine now has authentic 16-bit sound effects: 'select' beeps on keypad presses, 'coin' double-beeps when catching coins in the game, 'drop' rumbles with screen shake when dispensing items, 'powerup' arpeggios when picking up your snack, and a sad 'gameover' slide when time runs out. The entire machine also shakes during dispense for extra arcade juice, and all debug console.log statements have been removed.
