Set Q1 to 6 so SFS can be 0.8.
WARNING : As far as I can recall Q1 can not be 6 (at xQ1=1 and DevBufSize=4096) but now this works. So, not sure at all whether you can do this without ticks (different ticks, just caused by a too low buffer size and btw talking about the NOS1).
These settings do not work well with my version of XXHE. I have to turn the upsampling down to 4x to not get KS/WDM errors on Redbook.
