My wife has severe hearing loss and wears hearing aids. She uses a device to stream the tv audio to her hearing aids but she still has difficulty understanding what is said. Most tv shows have so much background noise music etc it's hard for me to follow what is said in a tv drama. Is there a way to extract voice channel only from hdmi output of our cable DVR?
My Cable DVR had an optical audio output so I ordered a 6 foot cable with the decoder. The decoder came with a short optical cable but I needed it to go through a conduit to our TV over our fireplace.
I installed this hardware today and it's a great solution to our problem. Eliminates all of the embedded surround sound and provides primarily clear voice only output to my wife's hearing aid streamer!
11-17-16 update, The decoder using a feed from my DVR had a time delay with the sound and the speech did not sync with the lips. I have ordered the HDMI audio extractor now. This should sync the speech with the lips!
