Actual codecs
avc1.66.30 (Constrained Baseline), mp4a.40.2 (AAC-LC)

@SlainTrue if codecs are not specified in main manifest, then hls.js tries to guess them, by parsing audio/video samples.

in your case, CODECS is not specified in the main manifest, and audio sampling rate is less than 24kHz => codec is guessed as HE-AAC : refer to logic here : https://github.com/dailymotion/hls.js/blob/master/src/demux/tsdemuxer.js#L536-L541

manifest codec:undefined,ADTS data:type:2,sampleingIndex:7[22050kHz],channelConfig:1
parsed codec:mp4a.40.5,rate:22050,nb channel:1

if you want to be able to playback your streams, you need to specify your codec is the main manifest (EXT-X-STREAM-INF tag)
