Thanks, looks like this is a silly bug with 8-bit audio formats (which are
rarely used for music):

    audio: fix gst_audio_format_from_caps() for 8-bit formats

    The endianness field is not present in 8-bit audio caps, so don't
    fail because of that when parsing caps into an GstAudioInfo structure.
    And if it is present, it should be ignored, because the format
    table we match against has a 0 value for endianness, so we need
    to look for 0 as well.

    audio: fix GST_AUDIO_INFO_ENDIANNESS macro

Unfortunately it's quite unlikely that this fix will ever get released. I would
suggest you upgrade your distro version to one that comes with GStreamer 1.x.

(I also don't know why the pipeline negotiates to 8 bit audio in the first
place in your case)
