I looks like there is need for that because it seems you have a problem accepting that other people do or like somethings different than you, judging by your reply's to various others. Maybe I'm "triggered" by that because sometimes I have a tendency to do it also but always try to prevent it.

Not at all. I was merely checking that veskop understood that the device where the stations were stored would be the same device where they were set up and he pointed me to a thread that was not the same issue as he was having.

judging by your reply's to various others.

I guess you are talking about the automatic updates discussion that we had. I thought I was quite polite with you.
Perhaps you misunderstood me.

I told you allready , i checked on my iPad, list was empty after firmware update this morning. App on iPad was up-to-date.

The list of URL's are stored at the phone/tablet where you added them. So a firmware update should not be able to delete them. A WiiM Home App reinstall will however do that.

Could you please tell us what can we expect regarding the issue and the proposition given? I also cannot deactivate HDMI in TV. Even if I could, I don't like this solution, as I watch movies with my audio setup. It's just not used on daily basis

I have no idea why they are constantly leaving @hgo58 and others in the dark on this. It seems obvious that the Ultra should be able to turn on and off how it presents itself as an ARC endpoint. This is basic AVP/AVR functionality and they already proved they can do it with previous betas. That’s the craziest part. Why ever disable useful options?

They even have the toggle in the WiiM Home App.

"Use HDMI Audio Only in HDMI Mode"

"HDMI audio" being HDMI ARC.
"HDMI Mode" meaning that the HDMI ARC is selected as input.
So: "Only enabled HDMI ARC discovery if selected as input"

It's just not working! And have not for more than a year.

My Ultra has now received this update, without any notification of an update being available, or any user intervention from myself, and I have been checking many times each day since it was announced here.

Same thing in my case.

Mine has also silently updated. Even my cat approves of the new playback screen option!

Let me pick up two of the ‚issues‘ emphasize in this thread.

HDMI behaviour
and
Automatic updates

I appreciate the critisim. But you (the posters) should be aware of your status as very advanced users.
The average user wants exactly those features. He can‘t be bothers with manually initiated updates. Nor will he accept that his TV sound is not present, regardless of any setting he may have changed more or less undeliberately.

Are you sure you understand the problem?

 

[Aquaman]

Are you sure you understand the problem?

Yes, I do. The HDMI thing may indeed be a bit annoying, if you are using it only on occasions. But the normal user will hardly even realise that Auto-Sensing set to OFF doesn‘t do anything.

OK, that is not the main issue though.
