I am using my device with an Android, version 2.3.4 Google play said I cound not download chrome because my phone was not up to date enough. However, last nite all of a sudden it showed up on my phone and I was able to operate it and direct chromecast on my TV. My only problem is I have no sound. Is it possible my device is defective? My phone doesn't seem to have any problem with sound. It shows up on the tv screen that I am trying to adjust the volume. It even said to raise the volume on the TV and I did. Still nothing. . .any ideas? Thanks
