Mediaelement or DirectSound for playing multiple sounds

My requirement is

1. to play multiple sounds at various intervals,

2. pause them, loop them

3. play them simultaneously (same time) in WPF application.

4. should be done in background. (No UI required for sounds)

Sound Player didn't support these features -> SoundPlayer

Also according to following link comparison I think DirectSound is best approach-> Various Ways
But nobody mentioned Media-element here.

Also I don't want any User interface/visuals just want to play sounds in background.

which one is better (performance and standard-wise)?MediaElement or DirectSound.
