(I also have ASIO4ALL installed for laptop DAWs, makes it even a little more pernickitty re. Must still be a driver conflict of some kind there with Windows. Works fine, but is not permanent, comes back from time to time. That's a summary of advice elsewhere from Microsoft, Dell etc. In any case, in my experience: 1) simply disable the realtek driver then reinstall 2) check sound options and ensure that no 'audio FX' (eg Spatial Sound) are enabled & also is set to 16 bit /48Khz. This also rears its head in other ways including the YouTube 'audio renderer' error which requires computer re-start (google other fora about that). Yes, I have this issue occasionally on my laptop (but not the workstation with RME IO & drivers). Not new, but working here so I recommend revisiting the driver for your specific hardware. I presume from the success some have had updating their drivers that this is worthy of attention.This is one we are using on one of the systems.
