Running NCS 1.3.7 on Server 2008 R2. When I view the feeds from the Web interface, I correctly hear audio when its enabled. However, viewing the feeds on both the iOS app and android app, I just get vdeo, no audio. This is while being connected to the local LAN that the server is on as well as from another wireless network. Additionally, I do get sound on items recorded in the library, just not the live feeds.
