No sound over HDMI on non native resolutions

[Invictaz]

If I select the game with renderer CNC-DDraw and resolution 1280x720 there is sound in the menu but not in game
If I select the same settings but resolution 1920x1080 there is sound in game (both Skirmish and online)
If I select the game with windowed mode it will work with sound and resolution 720p.
If I select fullscreen client on native resolution but game

This has something to do with modesetting. I tried the "buffer video" option but this does not make a change.

It does not matter if you choose Intel Graphics Driver 27 or later. Bug applies to all driver versions.

Have you tried other renderer's ?

[Invictaz]

Yes, all of them.
