today I've installed the new Catalyst 15.7.1 . I don't change anything and use the express installation.
But this time, I have no more sound output after installing.
I have the AMD Radeon HD 6900 Series graphiccard.
Win 7 latest update. (I've checked, no more updates possible)
As Monitor I use a Toshiba TV, connected with HDMI cable.
Since yesterday I'd no problems, but after the update there is no sound.
If I go to the "sound-configuration2 from window, AMD HDMI Audio Output is installed and selected. But If I say "Test" there comes this message:
" This device is used by another application. Disconnect all the devices that transmit audio currently on this device and try again. "
But there is no other application, or I can't find it.
If restart the PC, I try also re install the ne Catalyst software and speccially delete the AMD Audi driver and install only this new, but nothing works.
Could someone help me please?
Sorry for my Bad English
