FWIW I have used Wasapi exclusive in event mode since "day one" and have never experienced any audio glitches (Windows 7 SP1 Realtek audio). For a time there was an issue with the volume backing up sometimes instead of advancing on clicking/moving the slider (on push or event), but this was fixed over a year ago after a MusicBee update. I have been using the new basswasapi.dll version 2.4.3 since its post date on Un4seen and continue to have no issues. My environment may vary from others in that I always run the latest development versions of ALL the BASS libraries. As someone who is yet DAC-less, take this as just a "pedestrian benchmark."
