Creative blames Nvidia for X-Fi problems

Snap, crackle and pop

AFTER MUCH investigation into the mysterious crackling sound on its X-Fi cards, Creative has passed the buck to Nvidia for the problem.

According to the report, which can be seen here, Creative said that when it looked at the PCI bus on the nVidia nForce 4 motherboards when the crackle symptoms happened the Soundblaster X-Fi card PCI bus master memory requests for audio data were held off for ages.

There were apparently peak hold-offs of up to two milliseconds in some cases, which is unusual chipset behaviour at the best of times.

It is certainly "beyond the ability of a hardware audio accelerator to compensate for in its internal buffering".

Creative claims that the nForce 4 motherboard is the first motherboard on which these extremely long PCI service holdoffs have been observed by Creative.

However, Nvidia's Technical Marketing Manager, Sean Cleveland has responded in a Bjorn3D chat that the comment is pants and there were no open bugs regarding Creative's X-Fi audio card on Nvidian kit. µ
