MCE - HDMI - no sound

m4r · 10 Nov 2010

I have a system with the following specs, MSI K9A2 Platinum mainboard, AMD 6000+ cpu, 2gb kingston 667 RAM, MSI nx8500gt vga, fusion hdtv dual2 tuner card and pioneer blu-ray/DVD/CD-R, it was running vista with no problems at all hooked up to a sony HDTV via HDMI, this week i upgraded to windows 7 pro (fresh install) and everything was fine, then all of a sudden i have lost sound on certain channels 1, 90, 99 and 73, sound works fine on other channels. I have taken my box to a mates place and it all works fine again. The system is not hooked up to the internet at all.

Welcome to Seven Forums m4r. Does your mate have the same cable system (I am assuming cable?)?. Same channel lineup? Does the tuner card have a SAP (Second Audio Setting)? If so, make sure it's on stereo or mono, not SAP. A Guy

Those channels are outputting a digital format that your HDMI receiver cannot process. If it's a TV it's supposed to show an OSD (onscreen display) error when that input is selected. There is a workaround -- I'm not sure why this works but you can try as it's helped dozens of others with this same issue -- disable exclusive access to the device:
