Watching some channels i get that stupid audio description in background.

The dude sits down
The dude expresses concern
The room is filled with erotic toys

The story may be quite nasty as well...

However, this depends on which way the audio description is made / inserted.

- it may be included with the original sound track, voice-over style; no way to remove.

- perhaps standard audio track is stereo, but for some transmissions audio description is inserted to right audio channel, left still comes without; either select left only in channel props, or change the audiuo channel to left only on your audio system / sound card, or turn balance to the left.
On file playback, use sound card / speaker / audio system controls.

- maybe you are not on the standard audio track, but on a secondary one, change from channel properties

Same goes for bilingual transmissions.

BTW, you should have included details on bird, provider and station...
