Also, @Vasilich were you using TsReader as splitter? According to Owlsroost's comment there's a bug in TsReader which is probably responsible. No problem with LAV... but TsReader + LAV won't play audio.
You're a star!I've made good progress with modifying TsReader so that LAV Audio decoder can be used for ADTS AAC streams - expect a test version of TsReader sometime this week....
