It should be coming from the file name since that includes 7.1.  But the multiple audio tracks is interesting.

Below is the code that gets the audio from the folder / file name.
AudioChannelCustom is what is being displayed in the skin.
ListItem.AudioChannels is what comes from the scraper and this is used if a match os not found in the name. 

xml:


    <variable name="AudioChannelCustom">

        <value condition="String.Contains(ListItem.FileNameAndPath,1.0)">1</value>

        <value condition="String.Contains(ListItem.FileNameAndPath,2.0)">2</value>

        <value condition="String.Contains(ListItem.FileNameAndPath,2.1)">3</value>

        <value condition="String.Contains(ListItem.FileNameAndPath,4.0)">4</value>

        <value condition="String.Contains(ListItem.FileNameAndPath,4.1)">5</value>

        <value condition="String.Contains(ListItem.FileNameAndPath,5.1)">6</value>

        <value condition="String.Contains(ListItem.FileNameAndPath,6.1)">7</value>

        <value condition="String.Contains(ListItem.FileNameAndPath,7.1)">8</value>

        <value>$INFO[ListItem.AudioChannels]</value>

    </variable>

I'll try to look into this tomorrow.
