The only audio output is via IR. 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 > I have purchased three DAC units to feed a small audio amplifier and > a couple of bookshelf-type speakers.

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. -- [tim@localhost ~]$ uname -rsvp Linux 4.16.11-100.fc26.x86_64 #1 SMP Tue May 22 20:02:12 UTC 2018 x86_64 Boilerplate: All mail to my mailbox is automatically deleted.

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 on modern TV equipment, so I have this question: I have a Samsung * 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.

I'm aware of this difference in view like "it exists". But do not know details of the difference between proprietary and open implementation.
