I've been playing crysis 2 using dvi lead from my pc connected to my tv. I recently bought a dvi - hdmi cable so I could play in higher resolutions.

some of the resolutions ( higher end ones ) seem to cut the sound out when I select them. but the picture is displayed fine.

I then changed the game from full screen to window mode whilst in these resolutions, and the sound kicks back in..

I use standered audio jack for sound, not hdmi lead, so I'm not sure whats happening.

Anyone faced this issue before?
