Podobnie jak np. w płytach CD czy DVD.

A teraz wróćmy do tego o co w tej dyskusji chodziło i powtórzmy, że na
jakość obrazu taki kabel nie ma wpływu.
Przestań uparcie stać przy swoim bo zwyczajnie nie masz racji.
I nie porównuj kabli do płyt CD bo to w Twoim wykonaniu zwykła parodia -
sam pewnie codziennie słuchasz utworów 128kbps na YouTube.

Audio
Several companies claim that their HDMI cables sound better than other
HDMI cables. One in particular claims this is because there is no error
correction on the audio and its cables are more likely to transmit all
the data.
First of all, this is untrue. Audio over HDMI actually has more error
correction than the video signal. But even if this weren't the case,
it's still utter nonsense. Dolby has extensive error correction built
into its codecs. In other words, if you are sending the Dolby Digital
Plus, TrueHD, or whatever bitstream over HDMI from your Blu-ray player,
the data going into the DAC in your receiver is bit-for-bit the same as
what's on the disc. DTS presumably works in the same way, though the
company ignored my repeated requests for info. Cheap or expensive, the
cable is irrelevant when it comes to transmitting Dolby or DTS.
If the cable is faulty or if there is some cataclysm causing data to be
lost between the player and the receiver, the decoders are designed to
mute instead of blasting out compromised data. There is no such thing as
an audio version of "sparkles." Instead, you just get a total dropout of
the audio. So if you're getting audio dropouts, it's possible it's the
HDMI cable. But if you're not getting video issues as well, the problem
is likely elsewhere. If the audio isn't muting, then as long as you're
outputting an audio codec, you're getting exactly what's on the disc.
If you're playing a CD on a Blu-ray player, the output is PCM to the
receiver. This data is packetized, just like the rest of the audio and
video signal. As such, it is error-corrected. However, jitter is far
more likely than with an optical or coax connection. In discussions with
several audio equipment manufacturers since the original publication of
this article, I've been told by all of them that the DAC in the receiver
is going to have a far greater effect on the sound than the jitter in
the transmission. Before you leap on that, keep in mind that the DAC has
a smaller effect on the sound than the amp, the speakers, and definitely
less than the room itself.
Oh, and in case that wasn't clear, the jitter is inherent in the HDMI
transmission itself.
INNYMI SŁOWY: THE CABLE IS NOT GOING TO HAVE ANY EFFECT.
