Arc TV sound cuts in and out.

Same as above. I have a Samsung frame. I need to unplug the arc every time I turn the tv on in order for the sound to work. Otherwise, I get about 1 second of audio followed by 3 seconds of silence.  Please help!  Sounds great when it works.  

I thought it was fixed on my lg cx, but yesterday It dropped again switching from apple tv 4k back to live TV.

I was watching Atmos content, so perhaps the issue occurs more so when listening to atmos audio and back to stereo, dolby 5.1….

I have been exchanging emails with the senior software product manager at Sonos who has just sent me the below information …

We are currently focused on some Samsung issues and making good progress.  After we address those TVs, we will be moving onto the Sony.  I'm afraid the process of tracking down interop issues is a long one as it can take a while to replicate the issue(s). I cannot give you a timeline at this stage but it is worth noting that one of the solutions for the Samsung issues will likely improve,  if not fix,  your issues but we will need more testing. 

Keeping my fingers crossed ….

Hello, I just received my Sonos Arc for my LG CX, tried some Dolby Atmos content and then one hour in this issue already happened after switching to some Live TV.

The sound is cutting in and out for no reason and I can’t seem to find a workaround to at least fix it.

That’s a bit disappointing for a device this pricey.

I am having the same sound issues as everyone else. Sonos support have been in email contact with me and I have sent them the diagnostics. Nothing has been resolved. I now want a replacement - a newer model. I emailed Sonos and the reply email said that I would get a response within one working day - I have heard nothing yet (3 days on).

Would someone on the Sonos Support team get back to me BUT please don’t tell me to phone the support team as I cannot get through!

I have Sony A8h 65 with arc, sub and SL ones. I could replicate the issue of sound dropping out on particular content on Netflix. It wouldn't last 5 mins without a stutter or drop out. Since the latest sony update, around a week ago, I have had no issues. The Sony firmware update stated a fix for earc sound issues.

I will keep monitoring but this is not purely a sonos issue.

I was thinking about the issue that I had a few nights ago - complete sound loss when using eARC and no way to get it back, but all fine the next day. On the night when I was having trouble, I noticed that resolution on YoutubeTV (set to auto) was only 480p instead of a max of 720p on ESPN. It was a very stormy night and I ascribe the low resolution to some storm-related bandwidth issues. My point is that at least for that night, the eARC sound issues seemed to correlate with the lower video resolution, which was presumablycaused by lower than usual data transfer rates. Could these lower data rates impact eARC audio signal? Way out of my depth here, but just wondering if bandwidth might be an issue for eARC. 

I’ve been doing a lot of reading on various forums. Lg and other tv manufacturers and it seems this May not be specific to Sonos Arc or other soundbars. But possibly eArc out of the tv itself. I’ve also seen many complaints of this having to do with Apple 4K. Thoughts?

I highly doubt it..when perfect weather occurs, there are still drop outs.

My issue happens every 7 to 14 days. It would have to be 30 days of no issues for me to think it has been resolved. Sony Bravia XBR 65- 950G is my tv and have not seen an update yet, or it hasn’t arrived to me as they can’t update everyone at the same time.
