Voukoder not render 5.1 channel audio in Vegas

  • I tested the Voukoder connector 1.1.0 on Vegas Pro 17 with a project containing 5.1 channel audio.

    The rendering of Voukoder is correct. Here Media info shows 6 channels in the final file rendered by Voukoder.

    But Vegas Pro 17.0 has a bug in the So4compoundplug plug-in that causes AAC 5.1 audio channels to be imported into separate individual channels on the timeline.

    If the So4compoundplug plug-in is disabled in the internal preferences, the old Compoundplug plug-in will be used and will import the AAC 5.1 audio channels correctly in the timeline.

  • I confirm that the rendering of Voukoder is correct. The cause for hearing stereo in stead of 5.1 yesterday was probably my own mistake, viz incorrect configuration of the sound card. I disabled the So4compoundplug plug-in and indeed VP17 assigns the audio channels correctly now. So everything seems to work fine.

    But MediaInfo (17.12) keeps reporting 2 audio channels, while it reports 6 channels when encoding with Sony AVC/MVC. Attached is the complete report, notice the red lines:
