Help! Can't get sound from dvds on Alba TV combi

[Squareyes]

Can any genius out there help me please? Everything has been fine on my little Alba TV with combination DVD. However, I just happened to press sub-titles, by accident, on my remote control and since then I haven't been able to get sound on my dvds. The TV part is fine. The sub-titles are off and it's not on mute. I've checked the settings in the audio part of the menu and just can't resolve it. I've also read the manual several times. Any ideas?

Also see if there is a reset to factory default on the TV menus. Odd that is OK on TV but no sound on DVD. Is there a menu just for the DVD part of the TV? Check that if there is.
