This is not for a traditional TV setup.
I'm using a computer system which measures brain activity and issues audio signals for it to measure the brains reaction. In doing this, the system sends the audio data down an HDMI to the soundbar/speaker on the monitor. The HMDI is 12/15m long. Therefore I need a solution where I minimise any sound delay and quality as far as possible, such that the audio information sent from my system is received and processed by the speaker in the quickest time possible.
Now, I know that for such distances the recommendations for AV setups is to go active/optical for the HDMI. But I dont need to transmit high quality video signals, only audio (there is some basic video graphics which get sent down HDMI too, but not high datarate).
So I wondered whether I should be using a traditional copper wire HDMI cable or still go with an optic/active HMDI? I was thinking perhaps the additional processing that the active HDMI male heads do in the optic cables might delay audio more than a copper wire. But then I dont know how much a long copper HDMI also deteriorates audio quality.
