Well after all that, I think I worked out what the problem was, but only as a kind of
accidentally noticing something odd about the amount of RAM Win8 was reporting, as I was
gathering together some facts and figures for explaining what I was seeing in more
The PC itself, though quite old (ASUS P5W DH Deluxe / Intel Core2 Quad
2.4Ghz) now, seemed to have been handing itself quite well since I installed Win8 on it.
As I was checking a few details though, I noticed that it was reporting only 3Gb of
available RAM, rather than the 8Gb it's had fitted since who knows when exactly.
Previously, it's seen 2 different 64-bit Win7 incarnations, one of which was also as a
DAW. A little research prompted me to go looking in the BIOS for a setting on 'Memory
Remapping' - sure enough, it was disabled and effectively set to 32-bit mode, hence the
With that reset, SONAR was more than happy to switch over to
ASIO (for the Scarlett) and map all the necessary I/O, which it would not do with that
The only downside I've discovered in doing this so far, is
that the Scarlett does not sit comfortably with my Line6 POD X3 Pro, which also uses an
ASIO driver when connected by USB. Whilst I don't use that as a recording interface, it
does mean I can't change settings on it via Gearbox, as I've had to disable it in the Win8
'Device Manager'. That's more of an irritant than anything though.
Never in a
million years would I have guessed that a BIOS setting would have been doing something
