issue when streaming m3u8 source (multivariant playlist playlist)

[Alessio Carello]

Hello,
I hope everything goes well. I'm a sw developer working in a worldwide pro audio company.

We use gstreamer to send audio over the LAN, everything works fine except a case regarding MultiVariant Playlist (m3u8 file with tag #VEXT-X-STREAM-INF): after 9 seconds the audio stops.
The command we use is the following (I used gst-rtsp-server's test-launch example to reproduce the behaviour without using our code):

./test-launch "( souphttpsrc location=https://radiodeejay-lh.akamaihd.net/i/RadioDeejay_Live_1@189857/master.m3u8 ! decodebin ! audioconvert ! audio/x-raw,format=F32LE,rate=48000,channels=1 ! queue ! vorbisenc max-bitrate=64000 ! rtpvorbispay name=pay0 pt=97 )"

Now, if you open the stream in VLC (The URL will look like rtsp://127.0.0.1:8554/test) the sound will disappear in 9/10 seconds
I had the same issue when i changed the buffers, added queues, set is-live flag at true and did other tricks, tested with gstreamer 1.14.5 and 1.16.2.

Can you please help me to understand if the pipeline is bugged or I miss something?

Thank you all very much for your time.
