A sizeable portion of The Inbetweeners film aired last night on Channel 4 minus the voice track.
Whilst music and various sound effects were audible, the voices of the actors could not be heard.
A contributor on the Pres Café forum noted the voice track was absent for at least the first 40 minutes of the film.
Some viewers reported the issue was only apparent on the HD version of the channel.
