i had something like this that was resolved by tweaking up the
setting `PCI Latency Timer' in BIOS. the default was 32, but that
gave the helicopter sounds. everything over 64 was fine, and even
everything between 0-15 worked because the kernel figured out that
the latency was too low and turned it up to 64
