I did install the 'new' 4.2.7.6 driver but it not working here. When turing the POD X3 on it works for a short time with distorted sound, within a minute the sound stops, this for the windows sounds (included mp3's, spotify etc.). I have Realtek HD audio as a primary audio device running at 24bits 48kHz.
I didn't try the ASIO drivers yet with Sonar.
Hope this problem can be solved soon.
