Powernode 2i-HDMI randomly switches to HDMI input
Answered
Sometimes when listening to streamed services such as Tidal or music from my networked Library, the Powernode will randomly switch to its HDMI input.
I have a brand new Sony KD-48A9 with its HDMI-eARC output connected to the HDMI input of the Powernode.
The HDMI random switch problem occurs even though the TV is in standby. Disabling the Auto-sense seems to prevent the random switching happening......however, the random switching shouldn't happen in the first place, otherwise what is the point of having Auto-sense?
Any thoughts?

So, in recent weeks and months I haven't paid much attention to this problem but just tis week I have noticed what is maybe something new. When I have my Sony KD-48A9 turned on for picture interest only and I am listening to, for example, Tidal audio on the Powernode 2i, then if I turn the TV off, the Tidal sound gets muted. I can then, from the BluOS app, just increase the audio level once more and my Tidal sound returns. It seems the TV has not changed the Powernode audio source but it has caused the muting of the audio level of another source, in this case,Tidal.
It would appear that the Sony TV, connected by the HDMI ARC connection to the Powernode, is sending a "mute audio" command to the Powernode as it is turned off. Even though HDMI "Auto-Sense" in the Powernode's settings is switched off, the Powernode is still responding to this mute command.....which it surely shouldn't be!
I suspect that the Sony TV is also periodically sending such a mute command even while the TV is in standby, which explains why music from Tidal or other sources will go unexpectedly silent while playing, even though the TV is in standby.
I have to admit that on occassions when I want uninterrupted music for a party, etc, I have taken to unplugging the TV's HDMI lead from the back of the Powernode.......as inconvenient as that may be. This stops the problem completely.
Maybe anyone reading this could help shed some further light on this......in particular why "Auto-Sense off" doesn't seem to actually mean "Auto-Sense off" !
Many thanks.

Was the issue addressed finally? I have the same problem with my NAD C700 & SONY KD-55XG9505

I don't think it ever has been fixed.....I live with a workaround, not very satisfactory, but needs must!

It is sad! I spent lot of money for hifi with HDMI as must have and it is not working as expected.

Hi Przemyslaw,
I totally sympathise with you, it's all rather frustrating!
Sony TVs, amongst others also maybe, appears to send various commands to external devices via the HDMI ARC connection, even when the TV is in standby. The problem is, the Bluesound products seem unable to filter out which of these commands BluOS should respond to and which they should ignore.
I would have hoped that Bluesound product managers would have long ago had discussions with Sony TV product managers in Japan to work out a way to resolve this issue.......but they don't seem willing or able!
By the way, I used to work for Sony Europe and feel sure Sony would have cooperated, if asked.
Maybe you could raise the issue with Bluesound once again?
Regards.

Thanks Dave for your answer. I already created a ticket for NAD support. Let's see what they will reply.

Hi
I suggest you use the work around I posted above. It works some months later. I also used NAD support including log files to no avail.
Best of luck

Right, so after having read this post and a bunch of others, the conclusion is that neither Sony nor Bluesound are willing / able to fix this issue that's clearly plaguing dozens of users.
Bluesound's suggestion is to turn off CEC "and use IR programming for control". Great advice in 2022, when the majority of TV remotes are actually Bluetooth and when CEC has been around for over a decade. SMH.
Given that I bought the Node 3 online (picked it up today), I will be returning it tomorrow, likely marking it one of the shortest ownerships of the product ever. I have to say that simply because of this the Node 3 is by far the biggest disappointment of my entire Hi-Fi journey.
Maybe Bluesound could consider getting their heads out of their butt and actually do something about this, considering this issues was first reported over 2 years ago?

Tomas, very well said!!!

I didn't have this problem when I bought my powernode 8 months ago, but it has become increasingly unbearable the last few months. I feel like a simple solution would be to include an option where autosense only switches the input after 2 seconds of continuous input. But reading the replies here it seems that Bluesound is content with blaming another company, instead of putting some effort in solving this issue for their customers who bought an expensive product with an issue that defeats its whole purpose.

Totally agree!
Also, for what it's worth, I have had occasional problems with the HDMI link between my Sony TV and the Powernode locking up, such that even restarting both the TV and the Powernode won't resolve it. I have now discovered that clearing the Play Queue with the HDMI source selected in Bluesound app appears to restore the HDMI link. This is hard to prove since the total HDMI lock up occurs rarely. I believe there are bugs in the BluOS that Bluesound can't or won't address.

Hi David
Your diagnosis 6 months ago here was spot on; https://support1.bluesound.com/hc/en-us/community/posts/360051665254/comments/8311361777687
There are a number of things SONY appears to do with HDMI CEC that slightly vary from industry standards. Have you contacted SONY about this issue since your post and based on our experience with similar consumer issues we and our good friends at NAD Electronics have also seen in their AVR platform is the root of the problem you and other SONY TV users are seeing with CEC.

Hi Tony,
With respect, I am a customer, you are a product support manager........it is your job to interface with another manufacturer, in this case Sony, about interconnectivity issues between products from both companies, Bluesound and Sony!
I may well have worked for Sony in the past, but I am retired now. Your are much more likely to gain the attention of Sony product management, being an Audio HiFi manufacturer, than I am as an individual consumer.
Please try harder to get to the root of this problem area and hopefully solve it!

Hi Dave
As a fellow consumer, I would be angry and frustrated too, but unfortunately, with the problem you are having, I cannot help you with as much as I would like to.
I would be happy to clarify. Bluesound and its parent company work hard to ensure we are following industry standards for cross-brand interfaces by most other industry-leading manufacturers. Based on the feedback you have provided, and our own testing, we have determined the root cause of your problem is in your SONY TV your own troubleshooting confirms this.
We encourage you to continue to work with SONY to resolve the issue with your product and hold them to the same standards.
Thanks for understanding.

I have the same problem, with two different Sony TVs (65XK9505 and 65X94K) and with a NAD M10 and a NAD M10 v2.
When you turn off the TV, it mutes the NAD. And 1 time out of 3, when the TV is turned on again, the NAD remains on mute, or does not turn on.
When we look at the logs, we see that the Sony TV keeps sending CEC information.On the other hand, I can listen to another source for hours, I have no interference and the sound does not cut out.

Yes. Frustrating as this is as far as I know, it is only affecting Sony TV owners and I know from experience that similar problems with Sony TVs occur with Sonos products as well. It's always Sony TVs. No other brands that I know of so it's Sony's problem not Bluesound's. It's the main reason I would not purchase a Sony TV.
