Before that you is Beta user? Im is beta user from start, but i cant register the V1.2 UHD box     

Must be some internal miscommunication somewhere... 
Typical Astro 

tried to signup for beta v1.2, but it go straight to feeback page. does it mean that im not eligible?

I did that, but after I enter my IC number on the form, it prompts me to login to my Astro ID. Haiz.

I'm using ethernet, but still got this problem. Tried with wifi as well, same.
What is the latest version number? Mine only happen recently, which should be after the latest firmware update.

I think it might be even worst if they don't know that they need to put the decoder on standby mode.

Or perhaps they can have something like windows update where it will install the next update on next reboot.
Same here. Screen hang. I'm using the normal PVR decoder. Currently still facing the same problem.

Actually I'm not too sure about the details of the package due to the Astro is under my parent name and I just help them to make the monthly payment. As far as I know, Astro have stop issuing the hard-copy bill from last year onward. Only receive sms notification for the payment due.

About the 1 minute thing, I mistaken it. The grey message will shown up straight after away after turning on the Astro decoder. Sorry not to savvy in uploading stuff on the net.

The package is Chinese + English + News + Learning Channel and monthly payment is around RM106++.

My situation is where the grey message is shown in front (cover up the 3/4 of the screen) where else at the back there is still channel running.

What I'm planning to do is negotiate with Astro to get new decoder and remain with the current package. If not possible then will downgrade to Starter Pack + 2 Add On. And if still not possible then just terminate it and find alternative streaming platform.

You've just sign up OR have been a long time user who upgraded to ultra box?

If upgraded, did your package remain the same?

Well, I think what he/she meant is, how's the picture quality of all 4K UHD content?

And also, Sum Ting Wong, Ultra Box is very dependent on Internet connection to access to interactive features like cloud recording, Video On Demand, and so on. Without Internet, you can only press channel numbers to watch TV channels (including Astro UHD channel 780) and pretty much nothing else. Just like using Astro HD box.

So make sure your internet connection at your home is performing well.

How could you blame UBox since it is connected direct to TV. Your ARC is between your TV and your soundbar. So, it has nothing to do with UBox

The HDMI is related to CEC (Consumer Electronics Control), what you experience can occur since HDMI-CEC communication can vary among AV equipment manufacturers and TV manufacturers. YOu can read about CEC here

I would suspect the UBox also after what you described 

What is the audio output format you set on the UBox; Auto, Dolby 5.1, Stereo? My A/V also sometimes lost audio when switching between Stereo and Dolby. Perhaps this is the problem. I think using Dolby, you will not have sound on SD channel  but then using Stereo, you will lost your Dolby 5.1 

Because they made the Ultra Box to be compatible with Dolby Atmos, although Astro does not offer any content/channel in Dolby Atmos yet.

Which channels you face the soft volume issue though?
"Ehhh cannot... Later those Chinese customers make noise. You've seen what happened when we ceased Asian Action Channel and TVB Classic Movies. Some viewers especially the elderly still relies on Astro to watch classic shows, and some of it are one of the reasons why they continue subscribing to Astro"

Some viewers be like "If it's not because of my elderly parents, I would have cancel Astro long long time ago"
Which channels you face the soft volume issue?
And how's the configuration of your AV system like? You connect it via HDMI or digital optical cable?

I too had this problem too,it goes away  if I off the mains and switch on again,now its gone

What did you do to solve the problem? Just off and on both UBox and TV?. It has some problem with firmware since it is firmware control. Did you ever try to change HDMI cable?
