Behringer ASIO drivers disappeared. Low end Behrigner devices (audio interfaces, Xenyx mixers) used to have Behringer custom drivers (WDM and ASIO). They was also advertised as 'Ultra low latency'.
These drivers had some strangeness: they was not really utra low in latency, ASIO buffer size was affecting WDM (system) sounds and ASIO mode was not blocking system sounds. But they was (and still are) working on all Windows incarnations (32/64bit, from XP up to Windows 10). At some 'unlucky' moment, they have completely disappeared from Behringer Downloads and replaced with ASIO4ALL. One Behringer supporter claims in the forum there are no such drivers! WARINING: these drivers are hard to find.
