I compiled from github on my M5stack Core 2 but I get no sound although I see the .ts files being dowloaded.

There are 2 URLs that I would like to listen to:
https://as-hls-ww.live.cf.md.bbci.co.uk/pool_904/live/ww/bbc_radio_scotland_fm/bbc_radio_scotland_fm.isml/bbc_radio_scotland_fm-audio%3d96000.norewind.m3u8
AND
https://radioitaliasmi.akamaized.net/hls/live/2093120/RISMI/master.m3u8
I have a M5stack Core 2 with internal speaker

I used this main.cpp:
examples/M5Core2WebRadio

There is no sound coming out of the speaker.
For the first URL I can see messages from serial indicating that the buffers are being filled but no sound coming out while with the second URL there is nothing at all. I have tried with m5stack/M5Core2@0.1.3 but no success.
Thank-you for your help.
Regards

Thank you.

These URLs may have different problems.

The first URL causes a problem in conversion from ts to aac.
To solve it, I have to modify AudioGeneratorTS.

The second URL returns URLs which have relative path.
Here is actual playlist which the second URL( https://radioitaliasmi.akamaized.net/hls/live/2093120/RISMI/master.m3u8 ) returned.

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=98730,CODECS="mp4a.40.29"
../../2093120/RISMI/stream02/streamPlaylist.m3u8
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=98730,CODECS="mp4a.40.29"
../../2093120-b/RISMI/stream02/streamPlaylist.m3u8

The program should request to
https://radioitaliasmi.akamaized.net/hls/live/2093120/RISMI/stream02/streamPlaylist.m3u8
or
https://radioitaliasmi.akamaized.net/hls/live/2093120-b/RISMI/stream02/streamPlaylist.m3u8.

However, it does not support relative path, and requests to
https://radioitaliasmi.akamaized.net/hls/live/2093120/RISMI/stream02/../../2093120/RISMI/stream02/streamPlaylist.m3u8.

So, I have to make the program support relative path.

I have tried to understand why I do not have sound using this weblink:
https://as-hls-ww.live.cf.md.bbci.co.uk/pool_904/live/ww/bbc_radio_scotland_fm/bbc_radio_scotland_fm.isml/bbc_radio_scotland_fm-audio%3d96000.norewind.m3u8

From what I undersand AudioGeneratorTS does not find the sync byte 0xFFF
What can I do?
