HLS over IIS with Smooth Streaming Format SDK

I'm trying to run HLS over IIS and Smooth Streaming via Silverlight works fine but not HLS. What I have:

• New Live Smooth Streaming Publishing Point with HLS support enabled;
• Connected Publishing Point via Smooth Streaming Format SDK and sending H264 samples to IIS in live mode.
• IIS creates *.ismv, *.ism, and empty *.m3u8
• Smooth Streaming over Silverlight goes fine.

Problem is that there is no *.ts files created and m3u8 file is empty as well, that's why HLS doesnt work. No errors or warnings in Event Viewer.

Note: *.ismv could be transformed to *.ts file with all necessary manifests via Transform Manager IIS extension which means (I suppose) that H264 stream is okay.

After some investigation I found what was the problem, to have HLS during live publishing you need to push not only h264 stream but AAC audio as well. Hope It will help somebody.
