I'm guessing you have auto sound on the SB switched off.
did you try changing the Rf setting that you had?
In my job I often do fault investigations and rule out what may be causing an issue to find a solution.
I havent had any issues with my connection, apart from on prime a couple of times I did notice sub dip. But on other sources I have never experienced this. And I don't ever loose the connection completely.
I do switch SB, sub and rears off at wall every night. Not sure if that would make any difference?
And I restart the tv once a week, and I did notice restarting tv and sb fixed lip synch issues in bbc iplayer app.
I wonder if it's something else causing the issues.
Does it happen on all sources or just some. Eg tv app, 4k player?
Do you loose the connection completely until you resynch or is a momentary loss of connection?
Does it do this on 1 specific sources eg prime tv app or on all sources?
What wireless devices do you have or could a device be interfering with the SB?
I would test by switching off any wireless doorbells etc to test. Though if you have neighbours using a device that possibly has interference you would not know.
I checked manual and wireless speakers use one of the frequencies below.
5150 - 5250 MHz < 18 dBm
5250 - 5350 MHz < 18 dBm
5470 - 5600 MHz < 18 dBm
5650 - 5725 MHz < 18 dBm
5725 - 5850 MHz < 13.98 dBm
The bottom range is in same range as 5g wifi channel 36
Channel 161 uses 5815 to 5795, which nest wifi such as bt hub, orbi etc will use for their back channel to link the individual satellites to the main router hub.
Try using a WiFi analyser to see if it is a possibility that something may be causing interference?
What tv model do you have connected to the SB?
Hi, thanks for the comprehensive response, sorry for the delay in getting back to you, I don't often get chance to change the settings etc, kids start moaning that it's boring as soon as I press the menu button. However the connection was particularly bad last night, for whatever reason, on the Youview app and digital TV, then the input on HDMI 2 (Vero 4K+).
So to answer your questions:
TV model: Sony Bravia KD55XH9005 connected via the eARC port (latest firmware)
HDMI 1: PS4
HDMI 2: Vero 4k+ box
Auto sound off.
RF channel off.
Wireless playback quality: connection
DSEE HX off
Audio drc off
Sound effect Dolby speaker virtualizer
Advanced auto volume off
eARC on (although didn't realise this wasn't active on TV until latest firmware update last week)
Don't usually turn the units off at the wall, just leave on standby.
No wireless doorbells installed.
Main router is in the same room
Soundbar and TV network connections are wired.
No wireless network appears to be in the range of the soundbar signal (see image)
It's a intermittent dip in sound. Most noticeable when the sub drops out as the overall sound quality suffers. Rear speakers drop out less so, only really noticeable when on PS4.
If I go to the menus the system says the speakers are connected, and if I run the test tone, there is no loss in sound.
Replaced all HDMI cables also.
Any advice would be greatly appreciated.
