HbbTV_DVB "audio sample descriptor type not found, sampling rate not found" error on all contents

[Murmur]

This error audio sample descriptor type not found, sampling rate not found error is found pretty much on all content, platforms are happy to playback a dash stream(hbbtv device, pc browser, mobile device). Is this FAIL status a false positive or just ffmpeg -a:c aac aac_lc impl does not want to write AudioSampleBox.sdType, AudioSampleBox.samplingRate fields? HbbTV specs explicitly wanted them be present?

• maybe not-well-known ffmpeg or mp4box argument could force values be written to a mp4 file if there is any real reason fields be present.
