LatencyMon and my Audio Dropout Quest in Cakewalk by BandLab Posted August 24, 2020 From my experience (and many reports in the Internet) Dell XPS (and some other models) have latency problem for years. Somehow it is related to ACPI, probably bad design or/and bug(s) in hardware (as with almost all parts in my, now a bit aged, XPS. USB-C, wlan, audio, etc.). DELL has never confirmed general problems there, but some firmware updates had "latency improvement" in Changelogs (without noticeable difference in practice). Some update has broken ACPI compatibility with Linux (my XPS was running Ubuntu like 20 years old Celeron after that update... I have found some discussion where Linux developers have refused to mitigate clear DELL bug on there side...), after that I run on old firmware. In practice, with network and all services/tasks disabled, XPS can run audio applications without dropouts (at least with RME). Any activity which access system information (and I guess SupportAssist does) can introduce "blackout" for several ms. That is indirectly confirmed by many users which disable corresponding drivers, so services/programs no longer can request information. But disabling some related drivers has consequences and it is unclear which service (especially DELL own) access which device/driver (and when).
