Every time I watch Corrie on itv player app just before the break or end of an episode the sound goes all crackly and then silent altogether. The ads start and sound is normal to start and then crackle and silent. Episode starts again, normal sound and then it starts crackling and silent again. I try and rewind back to where I had sound and it’s all silent. This happens every time I watch itv player and only happens with ITV player. BBC iPlayer and channel 4 app work perfectly on the same TV.
