Intermittent audio loss from cable

Hi Geri,

Yes, I have tried using eARC to loop the audio signal back into the receiver. And I still get the same result,

I would eventually lose audio. I do use HDMI 2.1 cable (2M).

To Recap v2:

Older Samsung TV and older Marantz SR7012 A/V receiver, new 8K HDMI Cables-Result-AUDIO LOSS

NEW LG OLED C2 TV and new Denon x4700H A/V receiver, newer 8K HDMI Cables-Result-AUDIO LOSS

eARC on both TV sets have been attempted and still have the same audio issues. HDMI 2.1 8K cables used

XBOX Series X multiple times Factory reset but kept games and apps.

Update, I disabled eARC and HDMI ON to OFF on the Denon receiver. And on the TV, I also disabled eARC. On the Xbox series X I disabled CEC and ever since then I haven't had an issue with the audio. I did notice when I enabled CEC on the Xbox, and choosing Dolby Atmos I lost audio intermittently, so I just left CEC off. Unfortunately I have to use 3 controllers to turn everything on now. Now I can choose different audio formats with no audio loss.

I'll keep posting this until people listen as I truly think this is the issue. The HDMI receptacles in the back of the console are set back too far and normal HDMI cables make a weak connection at best. The only known resolution at this point is to have
MS send you another cable. If you don't believe me, just measure the ends of the cables. Hold them up to each other to compare and you will see that the ends of the MS cable is slightly longer and there fore makes a solid connection.

I have been through all of these issues of intermittent signal loss, degrading signal loss, and from working pretty good at the start to not hardly working at all. I had the console replaced, tried 4 different brands of HDMI cables, a different cable box,
etc. It took a while and lot of fiddling with cables but after determining that it was indeed due to a bad connection and realizing that he ports themselves were fine, I got looking at the cables.

Hi. My name is Brilliant, an independent advisor. I am happy to assist you today.

I’m sorry to hear that you are having trouble with your wired headset audio. This can be very annoying and frustrating, especially when you want to enjoy your favorite music or games.

Here are a few possible causes and solutions for this issue:
- Damaged cables: Kinks or frays in the cable can weaken the internal wires within the headphone cable, leading to breaks or shorts in the electrical connections. This can result in audio cutting out or producing intermittent static. You can try replacing the cable with a new one or repairing it with some tools and materials.

- Cable connector issues: The connectors at the ends of the cable, which plug into your device or headphones, can become damaged or loose over time. This can cause poor electrical connections, leading to audio cut-outs or inconsistent sound quality. You can try cleaning the connectors with a soft cloth or a cotton swab dipped in alcohol.

- Dirty or corroded audio jack: Dust and debris can accumulate inside the audio jack of your device, causing poor contact between the jack and the headphone connector. This may lead to audio disruptions or complete loss of sound. Liquid damage can also cause corrosion or oxidation on the metal surfaces within the audio jack or the headphone connector, leading to poor conductivity and audio cut-outs. You can try cleaning the audio jack with a dry cotton swab or compressed air.

- Loose connections: If the headphone connector is not properly inserted into the audio jack, it can result in an unstable connection and intermittent audio issues. If the internal wiring within the headphones or the device’s audio jack is loose or damaged, it can also cause poor electrical connections and audio cut-outs. You can try reinserting the headphone connector firmly into the audio jack and checking for any signs of damage.

- Faulty audio source: Problems with your device’s hardware, such as a damaged sound card, outdated drivers, software issues like corrupted files, etc., can cause audio inconsistencies or cut-outs when using wired headphones. You can try updating your device’s drivers and software, running a system scan for errors, disabling any background programs that might interfere with your sound settings, etc.

- Incompatibility between devices: In some cases, the headphones and the audio source may not be fully compatible, leading to audio issues. For example, if your headphones have a different impedance than your device’s output port, it might cause distortion or clipping of sound waves. You can try using an adapter that matches your headphones’ impedance level.

I hope this helps.

Could also possibly be the HDMI cable, my cable worked perfectly fine from my Xbox to my monitor for a long time, then one day it became very intermittent, and then just stopped HDR completely.

Possibly try replacing the cable too.
