When it comes to cabling, with HDMI, one cable or another is not going
to affect sound (or no sound) going to the monitor.  They're all
supposed to carry sound and picture (the thing is aimed at consumers
plugging DVD players, and the like, into their television set, with one
cable carrying everything).

Generally speaking HDMI cables work, or they don't work.  Really crappy
ones that are too long for their own good will either give no sound and
picture, at all, or they'll continuously stutter between working and
not working.

There's a bunch of data lines in standard cables that carry sound and
picture, control, identification, etc.  There are some optional extras,
such as ethernet, and an audio return channel (ARC), but which won't be
a part of your issue.

ARC is to do with home theatre, such as a DVD player connected through
an audio amplifier to a television, with just one HDMI lead between
player and amplifier, and one HDMI lead between amplifier and TV.  So
far, playing a DVD on your TV and listening to it on your stereo is a
straight forward obviously easy thing to support, all the signals are
going in one direction (outward from the DVD player).  ARC allows your
TV to send sound back to the amplifier, so you can watch broadcast
television, and hear it through your stereo, without having to patch in
yet another cable.  That's why there's only one ARC socket on your TV,
you're only expected to connect one amplifier to the TV.  If you have a
multitude of players (DVD, video games, streaming boxes, etc), you
either connect each direct to multiple TV inputs, or to multiple inputs
on your amplifier in the middle.
