Thank you both for the replies and I may try the Beyonwiz forum if necessary but before I do can I just get a further explanation about the Wiz volume settings, as I get the feeling that these comments may be on the right track. The comment about the BWiz reducing the volume, reminded me of when I first set it up, that there was a setting, producing a horizontal indicator at the top of the screen, that went to 50 and then the volume control varied that downwards.
I feel that somehow this is the solution but the problem is I cannot find it where this control is, so I am hoping you can tell me (?). I have looked at all the settings I can find but it is eluding me.
Also, can you please confirm too that the AV settings should be on "passthrough"? I have played with these trying to get the volume fixed and could not really understand how it should be from the user guide.
Thanks,
Allamn
The volume control you're talking about is the volume control on the Beyonwiz remote. It's a rocker control marked VOL in the centre and + and - on the two ends of the rocker. Near the channel change buttons. It's possible that someone inadvertently changed the volume settings, perhaps they pressed the VOL button instead of the CH buttons, somehow accidentally pressed the button without noticing, or perhaps small fingers have been at play.
Most users report the best results when this is set to about 45-48.
It's not really possible to know whether "passthrough" is appropriate to your equipment without knowing how the audio gets from the Beyonwiz to the device that drives the speakers, and the audio decoding capabilities of what's in between. If it was working previously using "passthrough", the Beyonwiz volume control level is probably the best place to check first.
It's normally best to find a good overall setting for the Beyonwiz volume control, and then leave the actual volume control to whatever device is connected to the speakers, though it sounds as though that's exactly what you want to do.
