    Very disconcerting.

    On my tv they are in sync, but if I listen on my hearing aids, which
    connect by Bluetooth, there is a noticable error.

    Watching on a "smart" TV, a laptop, a tablet?

    What if you pause and continue the stream?

    What if you rewind to the start of the same stream, does it do the same
    again?

    What if you switch away to a different programme and then switch back?

    Do they start out in sync at the start of a programme, then drift
    further out of sync the longer you watch for?

    On my tv they are in sync, but if I listen on my hearing aids, which
    connect by Bluetooth, there is a noticable error.

    That is a standard problem with Bluetooth audio devices. I have some
    earbuds (in-ear headphones) and they have about 200 msec delay: that's
    the amount of picture delay that I have to enter into VLC to bring the
    sound and picture back into lip sync. It's a shame that other devices
    such as iPlayer and TVs don't have the ability to enter a picture delay
    for use with delayed-sound devices such as Bluetooth headphones.

    In my case it's the other way around - the sound is early. I feed HDMI
    to the TV set to display picture only, and use an audio extractor that
    decodes analogue sound from the HDMI stream and feeds it to an audio
    amplifier. I have an adjustable audio delay in the analogue feed that
    needs to be set to about 130ms for synchronisation to appear correct.

    I've recently acquired a bluetooth transmitter for headphones, and if
    I connect it before the delay, the sound appears in sync, suggesting
    that it's actually early at that point and the Bluetooth processing is
    delaying it so it sounds correct on the hedphones.

    Rod.

    The modern bluetooth 5 I think it is is a lot better I'm told. I have issues with older bluetooth devices as when I use the Iphone I can swipe past the button before voice over gets through the lame bluetooth in the phones.

    Ah, thanks, I could have checked first. I've just got some Bluetooth
    earbuds which are nicer to use than headphones but just tested and the headphones don't have the disturbing delay.

    Dilema as I watch quite a bit on iPlayer (on a desktop).
