+For overlay builds using audioreach kernel modules, the test automatically:
+- Detects the overlay build configuration
+- Sets required DMA heap permissions
+- Restarts PipeWire service
+- Waits for the service to be ready

+This happens transparently before tests run. No manual configuration needed.
