Hello all,
my FPS started emitting random crackling noise. Things I did:

- Uninstall/Clean install of drivers and software (several times)
- Tried any settings combination

In the recordings no crackling sound is noticeable using other output devices in the same computer, or when listened in other devices.

I own a KALEA-INFORMATIQUE PCI-E to FireWire card mounting a supported chipset. Any help?

Here the OHCI report:
