解决方法：给 audio 组件绑定点击事件，手动触发播放暂停方法！

wxml文件


<!-- 判断是语音通话，有通话记录，通话描述不包含'未接' -->
<view class="reference"
    wx:if="{{itemList.activity_type === 'phone' && itemList.activity_reference_id && tool.indexOf(itemList.comment,'未接') === -1 }}">
    <!-- 语音播放 -->
    <van-button class="ref-btn" wx:if="{{audioResourceMaps[itemList.activity_reference_id] === undefined}}"
      loading="{{itemList.activity_reference_id === currentGettingReferenceId}}" icon="play" type="info" plain
      data-reference-id="{{itemList.activity_reference_id}}" bindtap="getReference">
    </van-button>
    <view wx:else class="audio-box">
        <!-- 语音播放暂停 -->   
      <van-button class="ref-btn" wx:if="{{audioResourceMaps[itemList.activity_reference_id]}}"
      data-reference-id="{{itemList.activity_reference_id}}"
        icon="pause" type="info" plain bindtap="pauseAudio"/>
        <!-- 点击没有通话录音 --> 
      <span wx:else class="no-audio-text">未找到通话录音</span>
    </view>
</view>
