I believe the EVGA driver package installs drivers for the following USB interfaces present on the Nu Audio card in the 0.1.1 EVGA driver dated 2/1/2019. These three probably will show up in your Device Manager under USB Controllers.
- ASMedia USB3.0 eXtensible Host Controller
- ASMedia USB3.0 eXtensible Host Controller
- ASMedia USB3.1 eXtensible Host Controller
The initial versions of these drivers installed during my card install were dated September 2018. I experienced intermittent sound choppiness and dropout during music playback from all sources - Youtube in Chrome, Soundcloud in Brave, MP3 and FLAC in Winamp through both the DirectSound and WaveOut outputs. My troubleshooting found no excess delayed procedure calls, and LatencyMon believed my system should have no problems playing realtime audio, but my sound signal was still dropping randomly.
I manually "updated" each of the default ASMedia drivers in Device manager using Update Driver --> Search automatically for updated driver software, and picked the one found by Windows for all three ASMedia controller entries.
This "updated" driver turned out to be an older version of the driver than was installed with my card. The version found by Microsoft was 1.16.38.1, dated August 2016, but in the hour of testing all audio sources since changing the ASMedia USB controller drivers to the older Microsoft version, I've had zero audio dropout or stutter.
Will report back if I start getting stutter again. I hope this helps others experiencing the same issue. Maybe the subsequent EVGA driver package can enforce this version of the ASMedia USB controller drivers.
