Hi

Suddenly, my RME PCIe AIO soundcard has stopped working during wdm playback. It does work fine in ASIO mode in Cubase 6.5.5.thought?

I get no sound from the soundcard outside Cubase and when I go into the control panel / sound / playback (and selects speakers with the default soundcard RME AIO) and trying to run a test tone I get "failed to play test tone" message?

The sound card refuses to work outside Cubase in Windows in wdm mode, I get errors that says it's somthing wrong with my soundcard, even though the operating system says that the sound card is installed properly and working fine?

I have the latest flash and latest driver installed for my RME PCie AIO card, I've tried to reflash and reinstalled the driver for the card but still the same?

Operation system: Windows Ultimate 64Bit SP1 with the latest updates.

CPU: Intel i74930k

Mainboard: Asus P9X79 WS

RAM amount: 32GB

Network adapters: Intel® 82579V, 1 x gigabit LAN

Graphic card: Nvidia GTX780 with driver 335.23

Other installed soundcards:NO

Which audio software (version) shows the problem:

All audio playback application that uses the soundcard in my operating system in wdm like Spotify, Explorer, VLC media player and so on (no problem with ASIO thought inside Cubase?).

Best Regards
Mikael
