spyling

I got a DVR Avtech MDR-757 , with 8cam and 4 microphone installed. It works ok on my computer (browser and viewer) , on my iphone. Video and Audio feeds are fine on computer and iphone. Nevertheless, I can't find eagleeyes for my Blackberry Torch 9810 with OS7 and the eagleeyes on my ipad2 doesn't have sound. The speaker / volume icon is nowhere to be found. Therefore i couldn't enable the sound from those mics. The video feed are ok though. are there anybody can help me ? Thank You
