    BTW, i am wondering, why we use in MP different players for audio and video. LAV is able to decode/playback the most known audio file formats. I've asked this question already some years ago, never got an answer.

    Do you mean BASS for audio vs. DirectShow for video?

    Okay.
    For a start, it is possible to configure MP to play music with LAV.
    I expect (speculation/opinion) the default is not LAV for various reasons including:
    1. Historical - BASS has been around a lot longer than LAV.
    2. LAV didn't natively support DTS until v0.65 (April 2015), and BASS still supports more random/rare audio formats.
    3. BASS supports more audio/music-related features (eg. visualisations, spectrum analyser).
    4. BASS "just works" without any hassles.
    5. There's no problem including BASS in MP; on the other hand, including LAV is questionable.

    Why is LAV 'questionable' (just curious)?

    LAV 0.65 added native decoding for DTS-HD, standard DTS decoding was supported by much earlier versions.

    I did not know it, how to set it up? With poor LAV installation the AC3 and dts files in my case are not supported. I am using internal sound card (realtek) with analogue outputs (not the opticla one).

    Many thanks.

    The one problem I have with BASS is that it's not open source.
    See my comment there.

    That's also an issue I have. Though admittedly that could be adjusted through our usage of the BASS APIs. I believe I could see this by the levels shown in my spectrum visualizer, levels in the signal are higher when BASS is in use.

    I meant in terms of licensing... but yes, you're right - it's not open source. I tend to agree with hwahrmann's comment in the linked thread (lot of effort to change - is it worth investing that effort etc.).
