How to pull a single podcast source, using the Matrix field and loop? {% if block.type == "podcastBlock" %}
    {% for category in block.podcastChannel %}
        {{category.title}} 

        &lt;audio class="mp3" controls&gt;

        {% for entry in block.podcastChannel %}
            &lt;source src="{{ entry.audioFile.one.url }}" type="audio/mp3"&gt;
        {% endfor %} 
    {% endfor %}
{% endif %}`
Try using the limit:1

{% for entry in block.podcastChannel.limit(1) %}
