HDMI cable signal strength drop

I have a blue ray player located about 14 feet of cable away from out flat screen TV and the volume on the TV must be maxed out just to hear sound levels that the A/C or heat blower will dround out. I tried a 10 foot cable just to see if it was a bad cable installed but made no difference. Next I will move the blue ray closer and try a much shorter cable that came with it. Any suggestions or similar experience with this drop in sound signal? All comments welcomed. RV ing at WP AFB Fam camp this weekend.

Hi and welcome to the forum.

I don't have any direct experience using HDMI with Blue Ray, but do have a 50' HDMI run from my DirecTv DVR to my bedroom TV. I see no degradation of signal but it does run through a powered HDMI splitter.

I have a hard time understanding how a digital audio signal would have the volume degraded over a 14' (or any other length actually) cable. Are there volume controls on both the DVD player and TV monitor? Maybe the DVD output volume is set low.

Best of luck.

Rick

I'm with Rick.

It's all digital and I would suspect a setting at either end.

I have to agree. There is no reason that the 14' cable would have any effect on the sound. Do you have a receiver and additional speakers within the coach? If you have a receiver and a TV that both have an connection for an optical cable feed that would be the way to go. Most TV's do not really have a great sound system. As Ric said with a HDMI cable connected from the player and both volumes turned on you should have lots of volume although the quality may not be so good

My bet is that there is a setting off somewhere

Good Luck
Dick

It's not the HDMI cable that is doing it. Something in your tv is not delivering the sound to the speakers. Check your tv's set-up instructions and menu options. Somewhere there is a setting that will deliver the incoming HDMI sound signal to the tv's speakers. It's probably not the default setting - people using HDMI are more likely routing the sound to a home theater system instead.

One more thought. You may have the wrong source on the TV. There should be a button on the remote or the TV that will let you select the correct source based on where you have the HDMI cable connected to the TV

I just received from Ebay a 10' Cheetah 3D capable HDMI cable @ $4.96 plus frght. These cables are much larger diameter and rated for higher digital frequency than normal HDMI. Absolutely no signal loss and in fact fits tighter in the connector slot than the Sony factory Blue Tooth player provided. Cable size, type of wire used, and shield can effect signal quality. Even though the digital signal is of a very high frequency, other frequency harmonics can create issues. So buying expensive cables can help but I have found researching ebay or Amazon, they can provide the same quality as very high priced cables. I suggest you review Cheetah cables and see if these could provide you with satisfaction.
The frequency of the the AC, the fan noise, and the air being pushed out by the air conditioner generates a wide range of frequency of sound plus a volume of sound. You may want to see if a Radio Shack has a sound meter. If so, con them into demonstrating their unit in your MH. The meter may help you understand the sounds you are hearing or not hearing and what levels sound( DB ) is being sent from each unit/speakers.

What is the sound output from the blu ray set for? One of the advantages of digital playback is that the difference from the lowest sound to the highest (measured in db) is much bigger than say a VCR. If you are playing this through a receiver set to decode DTS, DolbyPro Logic etc the sound is superior. But most Tv's will not reproduce normal conversation loud enough with most of these sound decoders. Can you set the player's output to stereo or Dolby 2.1 or better yet, night mode. Night mode will keep the lowest and highest sounds closer. If you send me your blu ray model I'll look up the optimal setting to use for TV use.

My TV has 2 audio/HDMI outputs.

One is full volume all the time, the other is adjustable.
You might check out that sort of thing.

By the way, I have been getting audio and video cables, switchers, etc
from an outfit called Monoprice.com
Great products sold at low prices.
