Thanks for your post and apologies to hear you're having an issue with the sound on your iPad.
As simple as this sounds, make sure you haven't got the sound switch set to silent on the device. This can sometimes turn the volume off to some apps as well as the tones for notifications etc.
If this is on and your volume is turned up, try deleting and re-installing the app to see if this helps.
Does the TV Anywhere app work OK?
What OS is your iPad running?
Let me know so we can help further.
