    I have found some that play in preview but do not through icecast - you get silence which does NOT fallback and the backend show progress bar progresses.
    If you find the same - could I please have links to these files?
    Trying to find patterns and need more bad files.
    Thanks.

    I now have 4 variants of mp3 codec encoding that wont work in icecast but do work in preview.

    Run all files through Audiacity -> stereo and they all work (LAME 3.9 128k 44.100 Stereo) every time..

    Infuriating, time consuming and very expensive.

    We didn't experience any similar issues.

    I have now identified a common factor.
    It is very odd that only I find these problems, when I find it on two separate Airtime machines.
    I have found traces of the same thing in old forum posts - which were ascribed to LS 'silence' handling or advised to restart LS and seemed to have no resolution. These people seem to have left.

    Here is one smoking gun of a silent playing file that LOOKS like its working in the back end.
    A dev told me mono playing is fixed. So this is strange.

    ls_script.log
