TV Anywhere MS8606 - No sound from VCR

[Raaid]

I've had this TV card in my MSI K7N2 Delta-ILSR MS 6570 based system for some time and had no problems with video or sound when watching analogue TV.
With the demise of analogue signals in UK, I added a DVB-T DIGITAL TV USB CARD TUNER and removed the aerial for the MSIPVS.
(The USB digital TV device works great by the way!)
Having removed the analogue aerial, I decided to connect a VCR in order to transfer old videos to DVD.
So, I used a SCART lead terminating in 6 RCA Phono plugs (2 x video and 4 x audio).
With the SCART in the VCR, I connected the video-out plug to the TV@Anywhere video-in and one of the audio-out plugs to the adjacent audio-in. 
The result, using the Intervideo WinDVR3 software, was good video reception from the VCR but no sound.
Using either the audio-out L or R plugs makes no difference, neither does plugging these into the m/b audio-in socket.

All settings appear to be correct, the Audio Input Device settings being  : -
Device:- NVidia nForce audio    Source:- Line In

I updated the drivers for the MSI 8606 audio Capture from Ver. 2.79.1.65 to Ver. 4.102.1.8 , but this did not solve the problem of no sound.

(I've also tried different tapes - all with sound - but no sound in WinDVR3.)

My sound system is working fine otherwise - so what am I missing??
Advice welcomed!

I finally read the small print in my MS-6570 M/B Users Guide!! 

The Appendix deals with using 4 or 6 channel audio.  My audio settings were for 4 channel audio, when in fact I was using only 2 channel.  4 channel is achieved by converting the back panel Line-In jack to Line-Out !!  So, unchecking 'Rear Speaker connected to Line-In' the Volume Control Advanced settings solved the problem!
