Mam płytę ECS k6s5a na sis745. Po zainstalowaniu s2k bylo obniżenie temoperatury, ale dzwięk też zaczął się psuć.Problem ten opisany jest na stronie http://www.cpuidle.de/faq.php
Q: My audio is all scratchy when CpuIdle is running?
A:
This is a problem with certain chipsets. According to some users, either on-board sound or PCI sound might work better.
If you are using a VIA chipset, or more precicely the VIA 686B southbridge, you can try the VIA latency patch, please consult Google (previously www.networking.tzo.com/net/software) for more details.
If you are using a SiS chipset (tested on the ECS K7S6A board with Award BIOS), you can try changing the BIOS settings. On the K7S6A, you can choose which bus is used to connect the on-board AC97 audio device, either PCI or embedded. Changing from PCI to embedded has been reported to work, the setting can be found under Integrated Peripherals -> SiS On Chip PCI -> AC97 Access Interface.
For nForce2 chipsets currently no workarounds are known.
W przypadku mojej płyty jak opisane wyżej trzeba zmienić opcje w biosie, aby AC97 łączył się nie przez PCI, a embedded.
