Audio problem on BB 2 3 and 4

For the past few days the audio on Bang Babes 2 3 and 4 has either been really faint even at max volume or completely gone.

It affects equally the corresponding Pad channels.

All other channels, Babe and normal, inc. Bang Babes 1 are fine.

I'm not on SKY but using my trusty old Echostar so I can't be precise about the Sky channel numbers.

But it seems studio specific because the audio stays lost even when a BB 2, 3 or 4 feed is moved onto BB 1, which is badged as Friendly TV on my EPG.

But no one else has mentioned it and the girls still talk into a, for me, dead mic.

So is this just me?

Ta in advance

Oops...solved..it was just me :

A change in the video feed on my AV mixer needed a corresponding change on the audio feed.

Bizarre how it just affected BB 2, 3 and 4.

Oh well, don't you just love modern technology and a rat's nest of cables
