Beam keeps playing after tv is off
any ideas
when i turn the tv off with the remote or when i ask alexa to do so, pithing seconds the beam continues to play the tv audio
any ideas why this is?
I'll chime in here and I say I also get this with my new (non OLED) LG TV when using Freesat using the built in tuner. Beam is connected from the TV ARC port with HDMI and the TV channels are from the built in Freesat decoder so no external boxes feeding the TV.
Get about 5-10 seconds of continued audio.
I would assume the TV has it buffered and continues to output after the TV is put onto standby. It can't be anything else.
LG TVs seems to be pretty buggy and don't play well with the Beam. But that's the LGs fault.
I still do have the exact same problem with my sonos beam in combination with my LG OLED C8. Both have been updated to the latest firmware.
Problem: The beam is directly connected too the LG via ARC. When I'm watching satellite TV and switch the TV off, the beam goes silent. After a couple of seconds the beam starts to play the sound from the last channel I watched on the TV while the TV stays black. The sound plays for a couple of seconds to a couple of minutes. After that there is a very loud beep and the beam goes silent.
Cause: I think the LGs pixel refresh is what causes this behavior. When the LG TV is switched off it will start its pixel refresh program. For some reason the LG outputs sound to the beam while the screen stays black. As stated above the sound is played as long as the pixel refresh takes.
Solution: Unfortunately there doesn't seem to be one. I searched the internet and tried some stuff myself. So far. Nothing worked. Probably this issue can only be solved by a firmware update from LG…
Does anybody have a solution to this problem?
Thanks for the quick reply.
For digital sound out I can only choose between "Automatic" and "PCM". I already had it set to automatic. So unfortunately that doesn't solve the problem
I set the digital out from "automatic" to "PCM" and did a couple of tests. Unfortunately the problem still remains. In each test the beam would be playing the sound of the current channel after the LG TV had been shut off. Same behavior as if the digital out was set to "automatic".
Also the beam only receives a stereo signal when the digital out is set to "PCM". So it wouldn't be a permanent solution even if it worked.
Guess I can't do much else than to wait for an LG firmware that fixes this issue. My current workaround is to set the LG TV to mute before I switch it off...
Unfortunately, in this manner, the Sonos is a ‘dumb’ device. If it receives a signal on the line in, it plays it. If there is no signal playing, it goes in to ‘low power’ mode after a short period of time. I would certainly hope LG could ‘fix’ this issue in an update relatively soon, since this issue would be across all devices, not just Sonos.
I have a LG OLED B8 with same issues - has anyone managed to find a working solution?
I’m not certain, but this is usually caused by audio pass-through on the HDMI ports, which I know on the later LG C9 TV can be switched off. I think LG may have fixed the matter on the C9 recently with the v04.80.03 firmware update, so perhaps see if there is a similar update for the LG B9. It’s definitely an LG matter rather than a Sonos issue.
Do you have your Beam connected to the HDMI_ARC port on your TV or through another device?
OK...that doesn't answer the question...
Is the HDMI cable plugged into your TV or your Cable Box (decoder)?
i had it in my old lg tv and it was fine
I've recently upgrading my lg tv now i get this problem
Unfortunately I'm going to have to say that the problem is not with your Beam but with your LG and or how you have your connections with your cable box. I'm leaning more toward the latter. The Beam has no way of intercepting a closed loop signal that is coming from your ISP and/or Cable provider.
However, there is an exception and that is when you are dealing with Over The Air (OTA) programing. Under extreme circumstances and all the planets aligning correctly it might be possible for the Beam to pick up an audio signal. Here in the USA the Federal Communications Commission (FCC) mandates the following for all consumer electronics :
Federal Communications Commission Radio Frequency Interference
Statement
This device complies with Part 15 of FCC Rules and Industry Canada's licence-exempt RSSs. Operation is subject to the following two conditions:
(1) this device may not cause interference, and
(2) this device must accept any interference, including interference that may cause undesired operation of this
device.
So, unless all you watch is OTA the likelihood of the Beam being at fault IMO is highly unlikely.
Th next time your issue occurs (TV audio being heard after the TV is turned off) please unplug the cable box to see if the TV audio ceases. If it does then you know what component is causing the problem or where to start. A couple more questions....
1. Are you using any type on audio converter or switch in conjunction with your LG, Beam and/or Cable box?
2. Are you using AppleTV for your programing content (in lieu of a cable provider)?
Please post back if you are stilling having the issue and even if it is resolved as I'd like to know what was causing the problem and how it was resolved.
Cheers!
I don't use any cable box or any converters. i watch freesat which is built in to the tv. so i have the HDMI from the tv into the beam.
interestingly though ive only just upgraded my tv and i didn't get this problem before so i didn't think it would be the beam.
maybe a setting on the tv?
did anyone get this sussed...? My Beam is straight into the TV (LG) seems to be playing on for longer and longer after I’ve turned the tv off... 😤
Assuming the LG is working properly try turning off your decoder box (i.e. the box provided by your ISP). If the noise stops then that is what you need to do going forward.
as with the earlier posts, didn’t do it with my 3 year old LG, just the new one 🥴
It sounds to me like it's an issue with the TV. When you turn off the TV, it should be turning off any thing that's running through it, including HDMI-ARC and any optical output, since those devices shouldn't be getting any power from the TV at that point. It sounds like, for reasons I can't understand, your TV is keeping these external processes going. It's most mystifying. I'd be calling LG.
