Since on the topic of HDMI cable, I would like to post a problem I encountered recently and hope someone over here can help me. Tried asking for help in the Audiophile section, but didn't manage to get a response.
I just bought a new IPTV box and it seems that it is messing up the audio connection of my Sony TV and Sony AV receiver/Bluray player.
The receiver and box are connecting to the TV individually.
When I connect my box to the TV, there's an audio communication error between my TV and receiver. Likewise, the same thing happened when I connect the box to the receiver. The error also caused the Bravia sync to stop working. The Bravia sync allows me to control both my TV and receiver with the same remote.
I then pin pointed the fault to the HDMI cable.
I have a 3m long HDMI cable with ethernet function, bearing product code no. E321484, which upon connecting the box to my TV, the audio communication error occured. Another cable bearing E380044 doesn't work as well.
I used another 1m long HDMI cable, bearing product code no. E252840, and it doesn't affect the audio.
The 3m long HDMI cable is also thicker than the other one.
Hence, I would like to know what is the difference in the specification for the E252840 HDMI cable. I suspect it to be a old model cable, however I have no knowledge of it.
Tried calling Sony on the requirement of the HDMI cable, in order for the Bravia Sync to work, they couldn't provide any either. They can only advise me to use a Sony HDMI cable, but the maximum length is only 1.5m.
Thanks.
