Can I stream video and hear the audio on my Play-Fi product?

With the Play-FI Android, iOS, and Kindle Fire apps, no.  The apps are built to support streaming audio only.  

With the Play-Fi Driver for Windows, you can stream any audio at all from the PC to your Play-Fi products, including video content. It also offers a Video mode, which allows you to sync the audio from any video, whether from a movie file or YouTube, to any one Play-Fi product on your network.

Using the Play-Fi enabled products from Hewlett-Packard, you can enjoy a video on your tablet and stream the audio to your speakers with excellent synchronization.

If your Play-Fi product is AirPlay enabled, you can stream audio from videos to your speakers that way.  For more on AirPlay streaming with your Play-Fi product, click here.
