I've the following problem : when I start the live-tv of 7 mediacenter, I have picture but most of the time no sound. I get the soundback if I switch to another channel.
I'm using 7 media center on a fresh install of Windows 7 ultimate (Retail version). I've an Asus analog tuner (My Cinema P7131) and the driver is up to date. My motherboard is a Gigabyte GA-E7AUM-DS2H with an integrated audio device (realtek ALC889A). The audio driver is up to date.
Everything is working correctly on the same configuration under vista and vista media centre.
