Many Thanks Colin

I found the missing file manually and uploaded by double clicking on it (WinFUP direct, not Mconfig). I then uploaded the other three files again for good measure. Now G91_core_1_27.mfu (622kB) did not give me the "Note that not all flash memory in your unit is enabled" message. Not sure why MConfig did not automatically identify this missing file as necessary to upload. They were all in the same directory.

But - nothing seems to have changed. Still get the DSP Disabled message and playing CDs shows 44k PCM i.e. a lower case k not a K. Wouldn't I see 44K if it was upsampling?

Can anyone else confirm if a G91 set as Type 0 playing CDs shows 44k or 44K, and also advise if pressing the DSP button gives a "DSP Disabled" message

many thanks (what a great forum!)
