My Wowza server is receiving the stream and transcodes it to H.264+AAC format. Test players (MPEG DASH, Adobe HDS) can play video, but doesn't play audio. Not via direct stream, nor the smil file. As far as I've found, H.264+AAC is the main format for MPEG DASH player. So why is it silent? The server itself can play audio, because if I configure MP3 audio output instead of AAC, Adobe players can play it correctly (but MPEG DASH doesn't work completely).
