Hello I had updated WowzaStreamingEngine 4.7.4 to 4.7.6 But it can not play live stream using smooth streaming. I think it is bug. So I have verified this problem with WSE 4.7.4 and 4.7.5. I tested it using WSE 4.7.4 and 4.7.5. (Ingest: RTMP, Output: Smooth Streaming and HLS. And hls is no problem) How to reproduce. 1. Install WSE 4.7.4 and 4.7.5 2. Comment ModuleCoreSecurity out in conf/live/Application.xml and set false at securityPublishRequirePassword 3. Set a .smil file at content/test.smil 4. Publish 3 streams using Wirecast 5. Check using Silverlight test player on IE11 Then - ## 4.7.4: works - ## 4.7.5: doesn’t work - Always returns 404 Not Found for audio segments. Maybe WSE 4.7.5 or later have the same problem with Smooth Streaming in live. It may be caused by related to this update.

There is no report of a bug in the update @Koji Mukoyama and we’d like to run some tests on your config to help identify what has broken. Would you kindly submit a support ticket so we may resolve this for you? We are aware of this change in 4.7.5 and will assist you: - Fixed Smooth Streaming when using NGRP/SMIL to correctly return a complete manifest when audio-only is listed as the first entry Thank you.

We have met the same issue (404 on Silverlight audio chunk requests) running Wowza 4.7.6. It is OK again after downgrading to Wowza 4.7.4 ---

@Rose Power-Wowza Community Manager Any update on this one? We are using version 4.7.6 and also facing the same issue. This seems to happen only when using NGRP and SMIL. ---
