Bug Fixes:

1. Playback: Corrected playback state display in certain cases.

6. Alarms: Corrected behavior in Daylight Saving Time zones.
7. Multi-room: After ungrouping, metadata no longer syncs to previously grouped (child) speakers.
8. Gapless Player: Fixed a near track end race condition that could trigger overlapping/simultaneous playback.
9. Local Files: Fixed an issue where the app progress bar reached the end before playback finished.
10. Amazon Music: Smoother seeking and playback—fixed occasional skips after seeking, progress bar desync, repeated playback of the same track after seeking, and unexpected stops when using Amazon Music Cast.

I don't follow your logic, the"most comprehensive streaming software is Sonos", yet "their interface apps are rubbish".?
Seems a bit of contradiction of terms there?
As you say "your opinion only".

Here's the streaming services for Sonos:

The app interface is another matter - I personally dislike its design & ergonomics.

A lot of Radio stations are in that list. I can listen to Schlager Radio

I think the Sonos approach was to devise a plug'n'play system (which Wiim have copied to a certain degree).

I believe anybody is able to develop a Sonos service which once approved by Sonos will be made available as a service.

It's hard to deny that Sonos is the most comprehensive system (which was the original claim made for Wiim).

@WiiM Team, @WiiM Support,

I have received this firmware update.

Upon checking the DAC filter, I note the default setting is Minimum Phase. Was this the filter applied prior to the update?


I believe the default for Ultra and Vibe was Linear Phase Fast Roll-Off Filter. (As I have no interest in filters, I wish to make no changes..)

Regards.

Well said, can we all please get back to the original topic of this thread, and move any Sonos discussions to a more appropriate place.

I simply replied to the assertion that Wiim was the most comprehensive streaming system. No need to use expletives to express your annoyance.
