Sonos Home Theater set up Skipping, bluetooth & Arc HDMI - PLEASE HELP!

Hello, 

 

I have recently purchased a new LG G5 OLED tv and a new Sonos Arc Ultra and Sub 4 (+ 2 ERA 100s, not hooked into home theater, they are set up in a different room). 

I am experiencing audio skipping that is quite frequent and very frustrating. Sometimes it happens every few minutes sometimes 2-3 times night. It tends to be more frequent than not. It happens with anything I stream from my tv, does not happen if I have my xbox hooked up or stream music from my phone. 

Here is my set up. 

LG OLED G5 (2025 model), hooked up with Sonos Arc ultra and Sub 4. This problem has occurred when connecting to my tv both through bluetooth and hdmi arc. This issue has happened since day 1 out of the box. 

 

To mention this issue did not happen with my new tv and old samsung sound bar, it only started happening with the new Sonos set up.

 

I love the sound from the sound bar and sub, but the skipping is driving me crazy. This is unacceptable for a $2k sound set up. I will return if issue is not resolved. 

 

I have done just about everything. 

  1. Multiple different hdmi cords (sonos and high quality brand new ones)
  2. cycled power between all items (multiple times)
  3. factory reset both tv and sonos
  4. upgraded my entire home wifi to top of the line wifi mesh network (1,000 mbps)
  5. all firmware for all devices are up to date
  6. adjusted group audio delay on sonos app

Please help!

I’d try several things. First, remove the Bluetooth connection…no reason to confuse the TV by offering it two methods of connection. Stick with the ARC connection over HDMI. It is greater bandwidth, and can carry Home Theater style formats.

Next, check the TV for updates, and install any that are found. Once that’s done, unplug the TV from the wall for at least 2 minutes, then plug it back in.

Then, check the Sonos for updates using your controller, and apply them. Once that’s done, unplug all Sonos devices from power, then reboot your router. Give the router a couple of minutes to come back up and reconnect other devices, then plug back in your Sonos. Again, give them a couple of minutes to settle down before testing.

Finally, if none of this helps, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, they get sensitive about GDPR.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Thanks so much for everyone’s help! 
 

I am confused why the skipping is happening as well. I thought it for sure hdmi arc would solve this. 
 

moving the WiFi router to another room helped for a bit but but skipping is back. 
 

something tells me its the arc ultras connection to the sub. If I disconnect the Sonos arc ultra and sub, no skipping with just tv audio. So it’s not my WiFi or streaming it’s 100% the arc and sub. 
 

Driving me crazy. For $2k, functionality misses 100%.

 

I will reach out to Sonos support tomorrow. Hopefully they can help.

Are any of the HT devices connected via Ethernet?  If so, disconnect the Ethernet.  The bond between the Arc/Sub is meant to be wireless.  It sounds counterintuitive, but an Ethernet connection can take a few more hops than the private, one-way, direct connection of the wireless bond, which can cause the stuttering you are hearing.

    No arc ultra and sub 4 are connected via bluetooth to each other then the arc ultra is connect via arc hdmi

     

    Time for a bit of explanation. The sub is bonded to the Arc Ultra. They communicate over a hidden 5Ghz channel that is not part of your network. The only time Bluetooth comes into play is during discovery/setup. Furthermore the Bluetooth in use is called Bluetooth Low Energy (BLE) which is not used to transfer audio. BLE becomes disengaged for all practical purposes after Sonos is setup.

    Also regarding your Surfboard the DOCSIS standard may need to be updated.

    Another, question…does your TV not have a HDMI eARC port? If it does that is where your Arc Ultra and TV should connect.

      Did you find a fix? I’m thinking of buying an LG G5 with Sono Arc Ultra soundbar with Sub 4 and some wireless rear speakers for surround sound
