The Issue: YouTube Videos no Sound After Download

One day I tried to download a popular music video from Youtube for my little daughter to easily view on the iPad. I successfully downloaded the YouTube vidoes by a free YouTube downloader downloaded from CNET, however the video play fine in WMP and VLC but there is no audio. I assume the audio codec of the video downloaded is not compatable with my computer, so I converted the video to MP4 format, still with no sound when playback. I then tried various ways to download youtube videos (download helper via firefox, but every time I download and convert, there is no audio.

I then found audio codec is missing in the video downloaded from YouTube, so even my computer was already installed the K-lite codec pack, there is no audio when playback on my computer.

I then tried to download YouTube videos with several paid YouTube downloader, still no luck (some paid YouTube downloader even can’t download the music video) untill I found Xilisoft Online Video Converter.
