a few days ago i faced an issue with my laptop concerning HDMI connectivity. i plugged my laptop to my tv to watch a movie but for some reason windows never recognized my TV in terms of audio output. it displayed fine on the tv but the sound came out of the laptop's speakers. after much search and diagnosis i came to the conclusion that the issue was with my latest Intel graphics update. i rolled back to the laptop manufacturer's recommended driver though its a few months old but i was able to resolve the issue. now my laptop is not a gaming laptop by any stretch of the imagination but i like to always have the latest versions of drivers.
i was wondering if any one has faced this kind of issue with their respective laptops?
Did you click on the Sound icon and select to have audio played out through this TV? This doesn't happen automatically. Windows cannot guess what you want; you have to tell it.
What versions worked and what versions didn't? If the versions that didn't work came from Intel site and versions that did work came from Dell site, perhaps there are customizations in the Dell versions. In this case, getting newer drivers may require that Dell be the one releasing updated drivers. Good luck getting them to do anything.
Did you try just one or did you work through the list of driver updates? If the latter, is there a specific driver release that causes the issues?
