[GI-XPEED LX3] Recording's sometimes have no sound on PC

[nsw9154]

as the title says when I transfer my recordings over to my PC sometimes I have no sound on them
even recordings made after one that works on the same channel with the same settings an Hour after it's doing my Head in
this also happens on my Solo2 and not only on the present build of Apollo I have had similar problems even on Zeus & Hellios
I have messed about with the settings but when I think that I have a setting that works the next recording might have no sound again
every recording works perfect on both LX3 & Solo2 boxes played through the TV
I recorded Robert Plant on BBC4 HD at 8pm no sound - but the Italian Detective program after it had sound
so I am thinking that they might be Doctoring the transmission to prevent unauthorised Recording :nono: are these settings correct

Just checked the recordings that I did last night, I purposely recorded Metallica at Gladstonbury on both my Solo2 & LX3 with the settings the same on BBC2 HD
Solo2 had No Sound but the LX3 Had Sound
I also recorded Brian Ferry on BBC4 HD strait after the Italian Detective program that I recorded as a test with Sound - it would not transfer over with FilZilla
all I got was a RED file transfer failed and I recorded that on my LX3 any ideas any one
