Hi
Can you use System Restore to roll back to a restore point when you did not have the problem?
Other wise go to mfr web site and download and re-install drivers

I want creative sound blaster live Ct4780 drivers


Hi,

I found this on the Creative forums posted by a Creative Forum Moderator:

http://us.creative.com/support/downloads/download.asp?DriverLang=1033&searchString=LiveDrvUni-Pack%28ENG%29.exe&Image1.x=22&Image1.y=8

It says Windows 2000/XP, but it will most likely be fine for Vista too.

Output activity showing but no sound.


Virtual outputs? in Echo console The phones output is Analog 1-2 and the line output is Analog 3-4. In the Echo console, you can choose between the Analog 1-2 bus and the Analog 3-4 bus in the upper right hand corner. In the Analog 1-2 bus make sure you have virtual output 3-4 muted. In the Analog 3-4 bus make sure you have the virtual output 1-2 muted. From within your audio application you can now assign your headphones output and your house (line) output. Hope this is some help.

I have Us-122 card and i can not install the drivers to my new laptop becouse there i have windows7. and every time i try a message says that i can not intsall the drivers in this windows session.


The Vista drivers work just fine for me on windows 7. To install them however, I had to run the installer in compatibility mode (the installer complains and quits if you don't).
For clarity, here are the exact steps I followed:

- Download the latest Vista drivers from http://www.tascam.com/products/us-122;9,15,68,19.html;
- Extract the .exe file from the package;
- Right click on the extracted exe file, select properties;
- Go to the compatibility tab, select "Run this program in compatibility mode for:" and in the dropdown box underneath select "Windows Vista (Service Pack 2)" (any Vista selection will probably work but this is the one that did it for me);
- Choose OK to save the settings
- Run the installer by double clicking on it and install as normal

You will have to unplug/shutdown the device before sleeping/shutting down windows or it may hang.

Hope this helps!

You must be using windows vista.

this error means you do not have hardware for sound.

if you are having this problem in desktop attach one headphone or speakr and it will work fine.

if you are using laptop try connecting headphone in jack it should work fine

Windows Vista Home Premium--Up to date This may be the problem. Vista is very much AntiPiracy. If you are ripping or such, Vista will give you grief.
