    BBC IPlayer runs late and slow

    BBC radio runs both late and slow. I shall explain.

    When I switch on in the morning the time checks are in sync with real-life, but progressively during the day the time slips - as much as an hour or so at the end of the day.

    And speech is ever so slightly slow - with the effect that presenters' voices sound deeper than they should.

    I'm running LMS (Max2Play) on a Raspberry Pi. I have a mix of original Squeezebox devices and RPi using piCorePlayer. I've tried limiting the number of devices running simultaneously, but it make no difference. I have updated kernels and versions of everything else I can think of.

    I have terrific broadband and a fast home wifi network.

    Any thoughts?

    What version of plugin ?
    What settings ?
    Have you changed the default Settings/Advanced/Filetypes AAC setting ? Can it still play native ?
    Does this happen on a single Touch/Radio player, not synced ?
    What other plugins installed ?

    BBC audio is at 48kHz- it "feels" like audio is being played back at 44.1kHz - this can happen if LMS settings are changed so that a player should play in PCM and not in Flac or native codecs.

    Thanks for speedy response.

    I'm running BBC iPlayer (1.5.4.5)

    Configured thus:

    Live stream Dash>HLS>MP3>FlashAAC
    On Demand Dash>HLS

    Settings/Advanced/Filetypes:

    AAC:
    AAC Disabled
    FLAC Disabled
    MP3 Disabled
    PCM faad

    Other plugins:

    BBC iPlayer Extra
    Date & Time
    Network Test
    Powersave
    Radio
    Visualiser Screensaver

    The phenomenon occurs across the estate, with different devices running independently. Coincidentally I cannot get synchronisation to stick, and have to re-enable it manually each time I want to use it.

    Regards
    John

    This is your problem. You have only enabled AAC to PCM transcoding. PCM has no header providing audio format details and so player assume a 44.1kHz 2ch 16bits stream.

    Use defautl AAC setting (i.e. enable AAC natove, AAC Flac ) and all will be OK.

    Why were the settings disabled in the first place ?
    Changing default settign should only be done with care as side effects are inevitable.

    Trust your own ears and use default whenever possible.

    Some of those suggestions have been the subject of very long "religious" arguments in the audiophile forum.

    Having messed around with those settings (and obviously heard things worse as a result) I unsuccessfully did search around for a listing of the default settings for "filetypes".

    Can you point me at such a listing?

    Regards
    John
