Hi all

I have repositioned my main tv remotely from my sky hd box and have run two pairs of cat5e and balun connectors to connect xbox360 and sky hd box to main tv

have tested all rj45 connections with a lan tester and all is fine

have all sound and picture on x box fine on both sets of baluns

but sky hd picture is fine but no sound just a muffled on off noise

run is around 15 meters

they are passive baluns

any ideas, i have tried all setting configurations on sky and tv and no cure, tried a different tv and get sound but still dropping in and out on sky only

would i need to use a powered balun instead?

Thank you!

Switch the audio out on your sky box to HDMI. If that's already done or doesn't work, switch your two HDMI leads around, could be a duff connection in one of them. Failing that, yes, a powered balun.

Don't think I've ever used an unpowered balun.

P.S. Hindsight is a wonderful thing, but I wouldn't have used Cat5e either. Cat 6 only for me when distributing HD audio and video over structured cabling.

Well as its only 15m or so i may rewire to cat6 cabling, its just i had a new 300m of cat5e from an old job

is there a significant difference in performance??

the baluns are meant to be good for 30 m without amplification apparently so a powered one may not help

its not the connections have tried both runs with other units and its fine, can only think its not carrying the sky hd properly as maybe its a higher quality requirement than an xbox ????
 
If anybodys interested, i removed the passive baluns and reinstalled neet pwoered baluns and works perfectly

i spoke to their technical engineer and he said at range of under 30 meters cat6 will have no visible benefits over cat 5e for transmitting hd1080i

trouble is the ac power supply is installed at the receiver end, which is a right pain if you tv is flat and being wall mounted as the ac plug is 2 1/2 inches proud behind the tv, what a cack idea
