VirtualBox disables ASIO analogue inputs on my MIA MIDI soundcard

[MarkT]

I am running Version 5.0.10 r104061 on an ASUS Z87-A motherboard with an Intel i7-4770 CPU and 16GB memory. I also have an Echo Digital Audio Mia Midi PCIe sound card which uses ASIO drivers. I use this as my main soundcard and have disabled the onboard soundcard on my Motherboard.

When I run any guest with sound enabled: Windows Direct Sound, Intel HD Audio, the ASIO analogue virtual inputs are disabled in all my audio programs (DAWs) and replaced with the digital S/PDIF inputs. If I disable audio in the guest the ASIO ports work correctly. If I select Windows Direct Sound as input, I can record on the host and still get sound from the guest. However, as I record music, I want the ASIO drivers to be available on the host.

VB should recognise all the audio hardware on the host and allow me to direct the guest to use the on-board audio hardware on the motherboard

"inputs are disabled in all my audio programs (DAWs) and replaced with the digital S/PDIF inputs. If I disable audio in the guest the AS" That should say inputs are disable on the host!
