Although loads of previous discussions on this subject, i haven't seem to be able to find the solution.
We have had virgin tivo for quite some years.. we have had a samsung soundbar connected by hdmi for the duration. In all that time when watching hd channels the sound cuts out. On researching the subject it came to light there was likely a fault with the soundbar.. so we didn't bother with the hd channels. We have just purchased a LG soundbar with an optical cable.. but have found we still have the same problem.
Can anyone enlighten me, if a solution has been found. Thanks in advance.
