    So not sure if fw related or xbmc but here goes:


    - what:If I am watching a movie and a notification sounds (ie incoming email) then it produces a digital/white noise for the time it takes to play the sound.
    - wich apps: XBMC
    - settings: HDMI Passthrough
    - connected accessories: M1 Mouse
    - did you root the device or flashed patches on it ? No
    - did you use official flash method or another? Official flash tool method with proper wipe and 1st boot

    EDIT: I also think its when mixing DTS or DD stream with system sounds as I think it's fine over PCM where it falls back ie when the source is not DD or DTS or over spotify.

    Am I the only one with this? Did anyone reproduce the issue?

    Cool thanks, I hope they can solve it or at least have notifications muted when passing through DD/DTS. Besides, a 'do not disturb' toggle while playing a movie would be a nice touch on a media player....

    indeed its just a temporary solution
    Note: it requires root

    I don't think this can be fixed. Passthrough is compressed audio, system notifications are uncompressed PCM. Your receiver cannot switch formats that quickly and that is what is causing the white noise.

    Ouch, unless either XBMC can mute all notifications when playing media or notifications be mixed with the passthrough stream.

    It can probably be muted, but I don't think they can be mixed (will have to research this).

    Yeah having XBMC mute them seems the most logical and feasible.

    i had my device for 4 days now i had the same issue with an addition. sometimes also screen blinks. i mean it goes black for 0,5 second and comes back. And nearly every 10-15 minutes i have the white noise. it is not just in xbmc. i tested and when i was listening from spotify white noise occured. i don't set up any e-mail account and i don't think it is from notifications for my case.

    I think it would be good to try another hdmi cable in your case

    Is there a solution for this now? (at the side of "mute all")

    You could easily do this with Tasker or a similar automation app.

    I have a profile that minutes notifications when certain apps are open and turns them back on when the app quits.
