It may be that this was all caused by windows pro privacy (blocking & disabling) tools, using cleaner on registry or using the SDI-tool to update drivers which turned out to be incompatible. Let me know if there is anything else I need to include that would be helpful. HDAudBus.sys – High def audio bus driver microshit. Netbt.sys – MBT Transport Driver, microshit. Wdf01000.sys – kernel mode driver framework runtime, microshit Tcpip.sys – tcp/ip driver, microshit Ndis.sys – network driver interface specification, microshit Acpi.sys – acpi driver for nt, microshit Not sure how to identify all these in device manager nor registry in terms of MSI = 1 I tried the hdaudbus = 0x00000001 in registry d_word And restarted the pc. Here are currently running LMon results: Just saw the guidelines for posting about latency issues. Going to update with trace file shortly.
