Quick Mix does not work in Windows 7. It sounds like UAC - User Account Control - is asking for you to confirm something on screen. Sometimes you have to alt+tab to focus the UAC dialogue box then do an Insert+b to find out what it is asking you then choose yes to allow or not not to.

Hello listers, I have a strange problem with my computer, I now and again and without any warning will hear uac saying something like uac and then my computer seems to go silent!!! I have to get my daughter to tell me what is on screen, the computer is locked then I unlock it in the normal way, but then it would seem that the sound card is muted!! I have quick mix installed and loaded settings that I had saved but it does not make any difference!! I have to get her to unmute the sound can anyone give me any way to stop this from happening? has anyone had this before? I am using window's-7 ultimate with all updates. with thanks. -- All The Best Kevin Cussick ** To leave the list, click on the immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=unsubscribe] ** If this link doesn't work then send a message to: ** access-uk-request@xxxxxxxxxxxxx ** and in the Subject line type ** unsubscribe ** For other list commands such as vacation mode, click on the ** immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=faq] ** or send a message, to ** access-uk-request@xxxxxxxxxxxxx with the Subject:- faq ** To leave the list, click on the immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=unsubscribe] ** If this link doesn't work then send a message to: ** access-uk-request@xxxxxxxxxxxxx ** and in the Subject line type ** unsubscribe ** For other list commands such as vacation mode, click on the ** immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=faq] ** or send a message, to ** access-uk-request@xxxxxxxxxxxxx with the Subject:- faq
