Looking forward to this update. One thing I have been wondering is if it could eventually be possible to route the Center channel signal to the Sub output on the back of the Ultra. I will never use the wired Sub output on my Ultra, mainly due to placement issues (wireless Sub works better for me). Seems like an Ultra in a media console has all of the outputs for Left Right and Center. I can put an Audio Pro C10 WiiM Edition in there, but seems like overkill to use a wireless hop so close. Probably the wrong place for this discussion but I figured I'd bring it up.

Dolby 5.1 Improvements: Support the center speaker and easily route .1 sub-channel audio to your subwoofer.

I don’t suppose this means anything in terms of offering the option to downmix LFE into the 2.0 output, per this thread and @WiiM Support response?

I’ve got my fingers crossed this will happen!

Obviously I’m having a bad hair day.

What does "Upgraded Soundtrack SDK" mean and what does it exactly do?

It refers to the Soundtrack service, which you are probably not using.

WiiM Teams Up with Soundtrack Your Brand to Transform Business Music Streaming

WiiM partners with Soundtrack Your Brand, bringing 100M+ songs to WiiM devices, delivering tailored audio experiences for businesses.

Soundtrack obviously published a new SDK (Software Development Kit) possibly supporting changes to the Application Programming Interface (API) and/or new software libraries.

Thank you! Pity, I was starting to get excited about it

I won‘t lose hope that there is an update coming which enables me use my Platin Hub lossless via DLNA. (One less cable) But it seems out of reach. Up to now there is permanent stuttering when try to use it.

Have you submitted a bug report via the more/feedback section in the app so WiiM can inspect your device logs for the cause?

Yes, I actually have done that in April but I somehow never received a reply. Maybe imy report wasn“t submitted.

If you submitted it thru the app, you should at least get an email acknowledgement

 

[Ronnie D]

@Burnside is correct, you should receive an email. However you need to reply to the email if you wish wiim to contact you about the issue directly. Also if you go to more/feedback in the app you will see an envelope in the top right hand corner and if you click on it, you should see your ticket there.

Oh! I forgot If you click on the wiim support tab on the forum, you will also see the progress of your ticket there.

Check out WiiM to see what 100 to 200 Euro / USD devices from the competition have for VU meters (and spectral analyzers).

I don't just want to be able to choose between poorly made and poorly made in a different color.

It can't be that hard, can it?

 

[Pragmatist]

Love this one

About as hard as posting in the correct thread.
Just kidding.

These are still completely wrong for a digital pre-amp. They do however look nicer than the current WiiM Ultra ones.

No, it fits right here.
They need to be reminded every now and then.

Is there any documentation on "Support the center speaker and easily route .1 sub-channel audio to your subwoofer"?

I found some passive speakers I like, but they may not have a matching center. the Ultra is L+R stereo output.

I still have my old Wiim Pro.

being able to set the center level in the 2-channel domain would be excellent. would rather not bother with a center speaker if possible.
