Never mind, Alan is probably right. If disabling PCIRetry does not work you can also try Option "NoAccel" (not a viable way to run, just to confirm the problem).
WRT singing capacitors, it does seem to be an increasing problem:

The difference is that singing capacitors will cause noise in the audio, while PCI stalls of the type Alan described will cause dropouts/stuttering.
