My daughter received a Surface 2 for Xmas from her grandfather. We have noticed that the volume in apps does not respond to the volume roc ker, or the master system volume. I found an in-app volume adjustment, which is nearly impossible to accurately set because it is so small. In addition, even setting 2/100 is too loud. Same situation whether headphones or built in speakers are in use. Anyone else experienced this or know how to fix this? Thank you.
