Depending on the site, volume and sound quality can vary from nearly incomprehendable to superb. For instance,trying to listen to streaming radio at WBUR the volume is unacceptably low. Trying to view the videos on this forum's Tips and Tricks, the volume is low and the little bit that comes thru is scratchy, to say the least. However, I get pop-up ads with the solitaire app I use, and if they have sound, they are clear as a bell and the volume is capable of peeling paint off the wall. Suggestions on getting control of volume and audio quality issues?
