Hello All and thanks for your input and help on all this - It is now finally all working!!!
I ended up having to reinstall the driver as I was no longer seeing ASIO or WASAPI devices to choose from - very odd... ? - I followed your tips above as well as the setup config provided by iFI Audio whom BTW, are excellent to deal with and make a really nice product!
One remaining question I do have, is when playing a 16bit 44.1Khz FLAC file, I notice it reads the following in DSP Studio:
Source 44.1 kHz 16bit 2ch and Internal 44.1 kHz 64bit 2ch - Is this correct and why the 64bit for internal? Also when I look at the Audio path, it says 'no changes are being made' but the Output reads: 44.1 kHz 32bit 2ch using ASIO (direct connection) - again, why 32bit and not 16bit which is what the file is encoded to?
Also, I noticed Mixing has JRSS mixing (recommended) enabled - should I disable this as I don't believe I need any mixing of sorts?
Again, appreciate the eduction and help and I am a lot happier now to be playing audio again...
Cheers,
Vin.
