Durec Player ...

Recording as usual, wav playback in VL Player is completely normal.
But via Durecplayer recently, old recording only left channel, new recording only right channel playback.
Am I missing something?
This is the case on all outputs, the indicator also only shows 1 channel on the device display.
Oh yes, it should have little to do with the OS, even if it is still W7 o)))

It's done, reset helped, everything is back to normal. TI ghosts o)
