I got the same trouble on my PC (win 7) when I installed it. I got the TotalMix FX icon on my Taskbar but nothing happens when I click it.

For the Windows guys, try disabling the "Use D2D" graphics setting in TM-FX.  I had to disable D2D on a PC using Intel HD4000 graphics - but the same card/drivers worked fine on another system with a discrete AMD video card.  Go figure...

Maybe you could let us know which RME device is in use here...

Newest drivers/firmware refers to which version?

And what means 'restart'? Exit the program and start it again? Nobody needs to do that. Or just close the window and click on the systray icon again?

I have no clue what is causing this and it is not a known effect. Even the D2D compatibility shows up differently (broken graphics).

ok - i tried some things:

after disabling the second screen, it immediatly worked! opening and closing with the tray-icon works as it should.

now: enabling the second monitor again - its still working... even after some reboots of the computer.
 
strange... but now i´m happy!

best,

It's quite annoying to have to reboot my PC to get un-TotalMix to work ..   I've replicated this problem on 2 PC's both with multiple monitors..  and the occasional crashes to blue screen .. some missed exception handling ..

Btw I can recommend "SheepDog". A little free software for repositioning windows that were on second monitors which aren't in action anymore.

We tried to reproduce with a three monitor setup but did not see any problem. So we need more details:

- you never mentioned what makes TotalMix FX fail. You only said it will work again after a reboot. So after the reboot what needs to be done to make it fail again?

- what is the exact configuration of your monitors? Which one is main, which one the portrait one?

maybe this problem is related to the monitor .inf ? just an idea, if you have the exact brand monitors listed in system properties, i would try and change to generic ones that supports the same resolution and see if the problem still happens..  may not work but easy to try..

Still waiting for an explanation...

Do you mean you simply switch off your Pc (complete shutdown, no sleep or standby mode used), then later switch it on again? And when it fails you do a normal warm boot, means simply restart from the Windows menu without completely switching off the computer?

Hi,
I have exactly the same problem.
RME UC

WIN 7 64 BITS
I 7 4770 3.4 ghz
16 giga ram

only 1 monitor, when I reboot, the TM work and visible, I close TM and after I can't open it, even with the icon in "sytem 32", nothing appears !?? I must reboot the pc !?

Please can you help me ?

I installed the last driver (1.0.48.0), the last firmware (119)...

Hi, all is ok now...but I don't know why !! ??

Any update here? Seems many have the same problem and I can not see any solution provided yet...

So where is the solution? I did not see anywhere here on the forum or other pages that RME has actually provided a solution to this. I have already tried countless of various options.

I killed the Totalmix by just ending the process tree. How do I find it again? I cannot locate where it is installed. I tried to search for it also. I cannot find it in the lower right corner anymore.

First of all, kudos for responding to this thread even though it was started a few years ago.

I've had this problem on and off for years... not being able to open a TotalMix window even though the icon is shown in the system tray and the TotalMix process is running.   I'm using:
-- Windows 7
-- TotalMix FX 1.43
-- Fireface 400 I purchased new around 2007
-- Cubase 9.0
-- Latest Norton anti-virus/firewall software

My PC has an AMD Phenom II processor, NVIDIA GeForce GTS 450 Graphics card and a single Samsung 27" monitor. 

One reason you might not get many complaints is that the problem is intermittent and you can usually reboot to resolve it.  It's mostly a nuisance.  I was prompted to post something here today because it took longer than usual for me to fix this week. 

But maybe this will help you and Charles820...

The problem is usually that the two icons in the system tray for TotalMix FX and Fireface Settings, respectively, are visible but I can't make the TotalMix window or Fireface settings window appear no matter what I do (short of rebooting).  Left-clicking on the icons does nothing I can see.   If I right-click on the TotalMix FX icon in the tray, the usual context menu comes up with three options: Workspace Quick Select, New TotalMix Window, and Exit TotalMix FX.  Clicking the 2nd option even brings up the dialog to specify the desired view (matrix or mixer) but when you click OK on that dialog, nothing happens (except I think it closes the dialog).   It's as if TotalMix FX thinks it's opening and closing windows but it really isn't.  I checked the last.Fireface4001.xml file at the window position values and they all seemed within the visible range.  Using Alt-tab to cycle through open windows doesn't cycle through any TotalMix window.  If I look at running processes in Windows, the TotalMix process IS running.  Sometimes in this state TotalMix still handles audio correctly.  But sometimes (like this week) it doesn't handle audio, as if it weren't running at all.  I can end the TotalMix process by right-clicking the TotalMix system tray icon and clicking Exit TotalMix FX.  This also makes the icon disappear.

After exiting TotalMix FX, I can restart it by running the TotalMixFX.exe in the System32 directory.  The TotalMix FX icon then reappears in the system tray, but this still doesn't fix the problem.  This also does not create the Fireface settings icon.  I'm not sure how to do that.

Usually a reboot fixes the problem.  But this week that didn't help.  The first thing I tried was installing the latest version of TotalMix FX (I was maybe a year behind).  I tried unplugging the Fireface 400, turning it off and back on, rebooting the PC with the FF400 off, etc.  I didn't try a different monitor but I was getting around to it.

But as a former computer programmer, I still knew of one advanced trouble-shooting technique which sometimes fixes the most intractable problems:  I jiggled the firewire cable in the back of the PC.   To my surprise, Windows said "found new hardware" or something similar, then it tried to install new Fireface drivers (I told it to stop, since I was already using the latest drivers) and then it asked me to reboot.  After the reboot the TotalMix FX icon worked properly, opening the TotalMix window as it should.  The Fireface settings icon worked as well.  I did have to instruct Cubase to use the Fireface ASIO drivers again, since Cubase had defaulted back the Windows generic ASIO drivers. 

I'm pretty sure a loose cable was NOT the cause of this problem over the years.  Since the cable provides the power to my Fireface, I know it wasn't completely unplugged when I jiggled it (since the unit was visibly powered on).  But it's certainly the first thing I will check from now on!

I can't recall any particular action that would make the problem happen.  I'd be working in Cubase or MS Word or whatever without any problems, but then I'd go to open the TotalMix window and it wouldn't open.  For awhile it seemed to happen almost every week, but usually it's less often. 

I realize it's difficult for you to debug an intermittent problem.  But if it happens again I will post more information.  Thanks!

I have the same problem in 2020.

Brand new Fireface UC, Windows 7 PRO SP1, HP Elitebook Intel CORE DUO 2.8GHz, ATI Radeon, Dual monitor, Docking station, 8GB RAM, SSD, Aero theme.

• I have plugged in the RME into the USB at the rear of the docking station (I think there might be USB HUB in the dock) and windows found no drivers (as expected)

• I have installed driver_usb_win_1168 (rmeinstaller.exe), then I performed reboot.

• After boot up two new icons appeared at right corner. Nothing happened after left click on both icons, only context menu on right click was working

• No change after reboot

• I tried to unplug the USB cable from the dock and I used shorter cable straight to the laptop. Suddenly, the Total mix window appeared. I tried to plug back the long (5m) USB through the dock, but now it is still working.

• I tried restart, it is still working. I closed the window by (X) close, then I click on icon at the task bar, everything is working.

It seems the problem is that for some reason totalmix or the system does not see the hardware. Don't ask me why.

I don't need help, I'm trying to give a clue to the others.

Yes, 11 years old laptop. Very reliable. I work as a repair technician in a major internet shop and I test various gear every day on it (Novation, Steinberg, Yamaha, midi keyboards, Line6, etc.). I have never had a problem with it, this was the first issue since 2011.

The total mix issue might be related to the USB HUB or chipset, that sounds about right to me. But strange thing is that after reconnecting directly to the laptop, then it works anywhere, even with the same port and long cable as originally.

Anyway, I was testing Kemper amp with SPDIF. The whole purpose of RME was only to get SPDIF to the PC and back... and to test the sync.

As I said, I don't need help
