Have you tried a different HDMI cable? I've seen issues where people
report problems and try a different cable and it's fine. There's
Yes. I tried four cables. Each of them on both TVs. Each behaved same for me. *however*
factr that I
had tried several different cables, does not mean I used different type of cable. they
are very
likely from same shop in my neighbourhood, likely same vendor and price level, just
bought in
different times.
completely different code paths between the upstream fully open
stack
that Fedora uses and Raspbian which uses the closed source proprietary
driver where the firmware actually does quite a bit of the work.
I'm aware of this difference in view like "it exists". But do not know
details of the difference
between proprietary and open implementation.
I was hoping for magical switch for HDMI, but looks lie there is none.
Thanx a lot!

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.

I realize that this is off-topic, but it sounds like you are an expert

I have a Samsung 24" HDTV (1920 x 1080) purchased around last May. It
has no electrical audio output, and of
course, the built-in speaker sound is terrible. The only audio output is
via IR. I have purchased three DAC units
to feed a small audio amplifier and a couple of bookshelf-type speakers.
On voice peaks, sometimes there is
a brief dropout of the audio. This happens with any of the DACs.I do not
believe that this is caused by the amplifier,
since I used the same amp on a previous TV that had a real electrical
audio output. The question: The DACs were not
really expensive units, I don't remember what I paid for them, but
probably around $20. Is this the problem, or is the
problem inherent in the TV? (BTW, this is the second of this particular
model--the first one I had had serious sound
problems and the store, PCRichard & Sons, finally exchanged it.) If you
think I need a more expensive DAC, what
sort of specs do I need and where do I get such a device? I do not want
one of those lay-on-the-floor all-in-one
speaker systems, whatever they are called--I have a perfectly good audio
system as it stands. and the
floor units would block access to the cable box by the remote.

Expensive TVs, crap sound, so you buy yet another hideously expensive
sound system. I really hate that. In the past, even modest priced TVs
had decent sound and pictures. And then you have the question of how
do you get audio out of them? HDMI, converter boxes, the headphone
socket (ugh)?
What do you mean by IR, though? The optical digital output using a
TOSlink cable? (Which isn't infra-red, by the way, it's a visible
red.) https://en.wikipedia.org/wiki/TOSLINK

do not believe that this is caused by the amplifier, since I used the

I'd either suspect the DACs or the TV creating the signal going to them
(optical outputs are likely to be from a processed audio signal, not
just piping the original data stream through). Do you have another
device with an similar digital output, such as CD or DVD player, that
you can test against?
Or do you mean very loud audio (as in you're running the speakers hard,
not that the audio signal went loud but while you were listening at a
quiet level). In that case, you may be running into thermal limiters
in your amplifiers or speakers.
