Summary	0002674: Audio "buzz/stutter" related issue 0002646
Description	Audio is interrupted with buzz/stutter corresponding to speedfan sensor scan interval. Speedfan is always run with /NOSUPERIO and "Enable Dell support" is enabled for the sake of functionality even though this is not a notebook computer. The audio issue is reproducible with or without the following command line switch: /NOSMARTSCAN This workstation features the optional Dell Nvidia graphics riser card which is a PCIe2.0 brige equipped with an nVidia chip to support SLI on two GPUs. (EVGA nvidia GTX560 x 2).
Steps To Reproduce	Start Speedfan with /NOSUPERIO and Dell support enabled. Play any media source with audio using either the onboard audio chipset or through Nvidia Hi-Def HDMI audio.
Additional Information	Gpu temps are properly reported, however GPU fan speeds are not accessible through speedfan but can be controlled with EVGA software. Running with the /NONVIDIAI2C causes application hang/system stability issues. Optional Dell Perc6i controller (manuf LSI) is installed with raid50 volume, smart status not reported but smart status/drive temps from the onboard SAS6 are properly reported. This system also includes optional memory expansion riser cards.

zampaz 2018-02-09 16:45 reporter ~0008523	Using the various options using configs in screenshots above I've been able to resolve "Stutter" to control fan speeds for Mem (zone1), CPU(zone1) and card cage(zone2) -chipset but lose pwms for fans four and five in zone3. The config is stable and I can use nvidia software to control nvidia fanspeeds (but can't overclock cards).
