    I just got a U2 Mini and I'm trying to use Tidal Connect and can't seem to get it connected. Any help would be greatly appreciated. Also anyway of getting the app to run on a Windows laptop

    - Disable Windows Firewall and relaunch Tidal app
    - If it still does not see the Lumin hardware, in Lumin app (on iOS or Android), set Tidal Connect to Off, wait for a few seconds, then turn it on again
    - Also try Tidal app on iOS and Android. On iOS you need to grant it "Local Network" permission. On Android you need to force stop it and relaunch it everytime.
    - If Lumin app does not see the U2 Mini, and Tidal app on all platforms also do not see the U2 Mini, state your brand/model of router, WiFi access points, network switches, and how everything are connected together

    Re: Lumin U2 Mini

    Thanks. One other question, I'm still trying to figure out the best way to control the Mini. I have a Samsung phone, just bought a Galaxy tablet and currently trying out Roon on my laptop because I haven't been able to get Tidal connect to work off my laptop. I am also thinking maybe iPad so back to my question. Does the Lumin app appear on all these devices the same way or are they laid out differently due to what they are, Ie iPad, Android phone, Android tablet etc...

    Re: Lumin U2 Mini

    Disabling the fire wall doesn't fix the problem. Tidal connect works from my phone but not my laptop. There is supposed to be an I con next to the volume icon in the lower portion of the picture I posted.

    Check the Windows Network type (on your laptop): it must be Private and not Public

    I checked it says private. windows fire wall is off, and I also shut off Norton and it still will not work. Tidal connect is active in Lumin settings

    Are the laptop and the smartphone both on the very same subnet, for example 192.168.0.xxx?

    They are as similar as possible, but the tablet has more room, so we put playlist and browse side-by-side. On phone you have to swipe to go from one to the other.
    iOS and Android are as similar as we can make them.
    There are screenshots here to illustrate the differences:

    If I were to hypothesize, from what I've read so far, this seems to be a Tidal Connect-based failure mode, and not a Lumin one.

    Re: Lumin U2 Mini

    I tested Tidal Windows app 2.36.2.54 on Windows 10 Pro 21H1. It can see and Tidal Connect to Lumin, and play successfully.

    Uninstall Tidal app and reinstall it.

    Make sure all firewall and internet security are turned off. Windows network set to private instead of public. Power cycle the whole network of devices starting from the router. If Tidal app does not see Lumin, toggle Tidal Connect on/off in Lumin app again.

    We have lift off. All I had to do was uninstall and reinstall the Tidal app. All security was left on. Thanks.

    Re: Lumin U2 Mini

    In my opinion all that for not so good sound quality. The Tidal connect app is great for interface but I vote it 3rd in what I have tried. In order of best to worst in SQ is
    1. Lumin app
    2. Roon
    3. Tidal connect app.

    So it looks like I have no choice but to use my phone or buy a tablet. I cast my vote for Lumin to come out with a windows app for us older folks that need a larger screen.

    Try that thread:

    Lumin App for Windows 11 for PC

    I stick with Linn Kinsky for Windows. There are some other apps like Asset Control and Upplay and some use a Android Emulator.

    I will try the kinski. I read that thread and tried the Linn Kazoo but Tidal wasnt showing up, just Qobuz.I really don't understand any of the computer stuff they talk about so I may have to wait for someone to help me hands on.

    My latest problem is for some reason when I go to play music from my NAS all songs are showing multiple times in the playlist. Some 3 in a row and some 4 in a row. No problem till today.

    Please install the free MinimServer on NAS, make sure to set the correct directory for your music.

    Disable your NAS DLNA/UPnP server if not needed for other purposes.

    Re: Lumin U2 Mini

    Now when listening to tidal through the Lumin app I can only add one song at a time from my Tidal playlist. It was adding the whole playlist and playing all the songs. I have not changed anything in the settings. And when i go to my favorite artists shouldn't they come up in alphabetical order?

    Ok now long press on the playlist album art adds all songs. Been trying that since 3am and it's now 8am. Good thing I'm retired.

    In Lumin app, between the left arrow button and the "Favorite Artists (# items)" there is a button to control sort order.

    You can just use Tidal app if its UI suits you more.

    Re: Lumin U2 Mini

    Any chance is there is a compatability issue via USB to a MHDT dac. Lumin via USB will play fine via my Pontus Dac but not on the MHDT Dac. Coax plays fine with the MHDT dac

    Sure, there is always the possibility of failure modes*. If I were to hazard a guess, it's the MHDT DAC itself, because many, many other U2 Mini users use their U2 Mini with many other USB DACs with no problems, at all.

    The fact that your Pontus DAC that also works fine with the USB interface with the U2 also indicates that the the problem likely lies with the MHDT DAC, and not the Lumin U2.

    If you want to continue to try to use the MHDT DAC, it would be helpful to perform an FMEA† as this wil be most effective (doing the RIGHT thing) and efficent (doing things RIGHT) approach to determine and remediate the root cause of the failure mode(s) when using USB. The website linked below is web page on how to perform an FMEA. Or, use Coax.

    If it were me, I'd just use the Pontus as...it works.

    Then you could follow Hans Beekhuizen's advice and..."Enjoy the music."😉

    Thanks for the info. I should add that the USB on the MHDT works with my BS Node thats why I was asking maybe an issue with compatability

    Yes, well, devices that are connected together usually...interact. Just as time and temperature, Time*Temp, interact when baking a cookie. Such is the nature of chemistry, physics, and engineering. And, with respect to bakin' a cookie, it is the Time*Temp interaction that produces a properly-baked cookie, not Time alone or Temp alone. And, this interaction is what quote often drives or results in what we refer to in DFSS* as the critical functional response (CFR).

    And, frequently, just as with bakin' a cookie, the "control factors" in audio system ...interact. It'll come as no surprise that just as time & temperature often interact when driving chemical reactions to completion, the same thing can occur in electrical engineering, audio engineering, or...the functioning of components in a stereo system.

    As such, when two components are connected by the USB cable, there are not two, but three functional components, and when connected together, they are not functioning independently of one another, they are functioning together as a system: the MHDT DAC, U2 Mini, and...the USB cable. And, just as with the example given above, these components often do not function completely independently of one another. They can, and often do, interact.

    So...if your BN Node works with the U2 and the MHDT doesn't, then it's quite likely there may be a specific MHDT*U2 or MHDT*U2*USB cable interaction between the two at the USB interface that is driving the failure mode.

    Which model of MHDT?

    Note that only one USB DAC can be connected. Do not connect two DAC to the Lumin via USB.

    Try using a computer printer USB cable.

    (It is, however, possible to connect four non-USB DAC.)

    It is the Orchid DAC. I was only hooking one up at a time. The unit is now sold and I needed to test it before shipping it out.

    From the Orchid user manual -
    "in
    case of no sound from USB port, please check if there is any device conflict
    by device management under control panel.
     Avoid using USB hub in connecting Orchid DAC. Signal through USB hub may not work properly and also decrease the sound performance.
    If none of these suggestions cure the problem, please do not hesitate to contact us."

    This is referring to if you are using a computer. There is no other control panel.

    Re: Lumin U2 Mini

    I pulled my Orchid out of the garage and tried it via usb with my u2 mini. No lock light on the Orchid. Mini is in usb mode under settings. The usb cable is a Wire World. Looking like our condition may be SNAFU. If you figure something out please post.

    Thanks for confirming but I sold the unit. It did work with my BS Node which I confirmed before shipping it out to the new owner. Just didn't confirm if he has a Lumin. LOL
