XG9005 connected to an amplifier problem

[iany1954]

I have a KD-49XG9005 connected by HDMI (ARC) to a Sony STR-DH790 amplifier and Youview set top box. I have a problem in getting the audio to be seen to be correctly routed. When switching on to use the Youview box (I use a Harmony 650 remote). The audio is always routed correctly to the amplifier but the tv shows alternately the messages ‘tv speakers active’ and ‘audio system active’ at each switch on. Although the sound always comes through the amplifier if I look at the tv menu it shows that either the tv speakers or the audio system speakers are active (dependant on the tv message displayed). It seems that although the sound is routed correctly the tv does not always recognise this!

I also have a problem in that if I use the tv tuners at switch on (using the Harmony to set inputs etc) I have to reset the amplifier input to ‘tv’ as the tv sends a command to the amplifier to change its input to ‘mediabox’ during its start up sequence.

any help or guidance will be appreciated.

Hi iany1954, 

Welcome to the community. 

I'll just see if I can find any help regarding this. In the meantime though, maybe another community member might have some ideas. 

Thanks,

Pascale

Many thanks, it would be great to find out what is happening. Doesn’t seem to affect operation but is somewhat confusing!

Hi Ian,

Have you tried a different HDMI cable? You can also go to TV Settings - Sound - Speakers to tell the TV what to use. If you want the sound to come out of the TV speakers, don't connect the amplifier to HDMI ARC and use a normal HDMI port instead.

No, I’ve not yet tried a different hdmi cable. All works well but the only problem seems to be alternate display of audio or tv speakers active at each switch on. I know I can change the speakers in the tv menu but even though it shows as tv speakers active they are not, the audio system speakers are always the ones being used! I’ll try a different hdmi cable and see if it helps.

thanks

Hi again,

Update us when you get around to testing that cable then

Hi, I’ve tried another, completely different cable with no change. I’ve tried changing delays and switch on order on the Harmony 650 and nothing helps. At each switch on the tv displays either ‘audio system active’ or ‘tv speakers active’ (alternate at each switch on). Whichever is displayed as active makes no difference, all sound correctly comes out of the audio system. If I go to the tv speaker option and it is showing ‘tv speakers’ changing to ‘audio system’ there is a changeover discontinuity period and the sound continues (correctly) from the audio system (and is displayed as such). I realise that I should ignore this but I’d like to know why the tv gets things wrong!

It must be something to do with the hdmi handshake, but as both devices are Sony surely I can expect that they will work together correctly?

Hi Ian,

In this case, let's go back to basics (check if the issue remains after each step):

1. Test the whole setup after removing each device connected to the receiver (except the speakers).
2. Update the TV.
3. Update the AV Receiver.
4. Reset the TV.
5. Reset the Receiver.

Hi, this problem has been with me for a long time. I have, at different times, reset both tv and amplifier. Both have latest software fitted (tv is actually a replacement for on which developed a different fault). I don’t really want to carry out reset again as it’s time consuming to set everything up again (though I have regularly restarted the tv).

I have carried out a further trial using only the tv controller. Despite hdmi control for standby and on/off being disabled on both devices, if I turn on the tv, the amplifier is turned on immediately if the tv showed ‘audio system active’ at its last use, and after about 15 seconds I get the incorrect banner ‘tv speakers active’. If at last use the tv was at ‘tv speakers active’ then after about 10 seconds the amplifier switches on and the correct ‘audio system active’ banner is displayed!

So, I have forced the amplifier to turn off 3 seconds before the tv (using the Harmony 650), this causes the tv to set ‘tv speakers active’ before it turns off. This then works correctly at each subsequent switch on.

As for the other selections (using Harmony 650, eg freeview and freesat on the tv) they always start correctly if the tv was previously started by using the ‘youview’ selection, otherwise they fail to select correctly. I’m  happy to leave this as is at the moment but I am convinced that there is some form of hdmi control problem in my set up.

This is all quite confusing and I’ll perhaps come back to it when I’ve nothing else to do!!!! 

many thanks for your interest,

Ian

Hi, slightly late to the party but having exactly the same issue with the 49XG9005 with a Q Acoustics M3 soundbar. Have you managed to find a solution?

I bought this TV around November 2019, and everything was fine, however after the latest firmware update around January if i remember correctly, this started happening. The sequence of events is:

- Switch tv on

- Soundbar goes on

- After 2-3 seconds, soundbar goes off

- TV shows 'tv speakers' active.

I can manually wake the soundbar up by going to the menu -> speakers -> audio system. Also, if I switch the TV off and then on immediately, the soundbar wakes up by itself. Sounds like this tv needs a patch.

The issue sounds a lot like one i found here:  https://www.sony.co.uk/electronics/support/articles/00223423

however this is for 2016-2018 models.
