#785 mouse freeze + sound bug while mumble is running

Mumble (544)

I wanted to install and use mumble 1.2.3.

When I launch mumble (installation finished succesfull without any complaints) then i hear about every 5 seconds a sound notification like if you have deplugged a hardware item and my PC laggs/mouse freezes for a moment. So it is impossible to do anything while mumble is running.

Mumble below version 1.2.x. works brilliant without any complaints!

What I've already tried to get it running:
- formated system
- tried mumble on complete clean system (only OS+Mainboard-, GPU driver)
- used onboard sound instead of soundcard
- used soundcard
- updated all drivers
- updated bios

OS: Windows 7 64 Bit

Mainboard Asus P6T
CPU Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz, 2672 MHz
RAM OCZ Gold XTC 6133 MB (DDR3-1066 Tripple Channel)
GPU NVIDIA GeForce GTX 285 (1024 MB)
Sound Creative SoundBlaster X-Fi Titanium Fatal1ty Champion
Headset Beyerdynamic MMX-2I hope you can help me with this bug.

    I am having the same problem. It does not occur if I use the Mumble11x.exe, but then I can't join my friends' server as they use the new protocol.

    Win7 64bit, Core2 Duo, Asus P5E-VM, onboard sound, NVidia GT240.

    Also, if I try to debug it with WinDBG, I get an error:
    Could not create process "C:\Program Files (X86)\Mumble\mumble.exe", Win32 error 0n740
    The requested operation requires elevation

    I get this error even when I try running WinDBG as Administrator (from it's shortcut context menu)

    I should also add, WinDBG DOES work if I try to debug Mumble11x.exe instead.

    OK it seems this was somehow being caused by the USB LCD on the front of my machine. I only noticed because the backlight blinked slightly each time the sound was emitted.
    I unplugged the LCD from the internal USB header and mumble works fine now.

    I would still call this a bug because I don't see what an LCD should have to do with mumble. Nor should it freeze the entire windows input system.

    I already fixed it to my self a long time ago.
    If you open the "device manager" of windows, you see and USB-Device popping up when the sound appears. After I saw this I totally deactivated&deinstalled this USB-Device since some tests showed that it wasn't the mouse and the keyboard. After this it works, and no feature of my PC was missing. All LEDS are working, so I can't imagine which problem Mumble had in this case.

    jimbowen: Can you stop Mumble, plug the USB LCD back in, and try to get a USB ID from it? Open up Device Manager, right click the device, pick properties. In the "Details" tab, pick "hardware IDs" and maybe "compatible IDs" from the list and note down as much as you can.

    It's not part of Mumble I'm familiar with, nor do I know how useful the information I'm asking from you may be... but I'm wondering if the Logitech keyboard LCD stuff (which I think was reimplemented since 1.2.2 since they open-sourced their stuff) may be erroneously thinking that some other devices are logitech keyboards, sending some data, and the driver/controller is puking and restarting?

    Again, completely uneducated guess - I'm not sure whether it'll pan out but if it's not too much trouble for you to grab that information that'd be a start. :)
