Possible solution/action

ISO IEC 14496-12:
Fix the muxer in order to correctly fill samplerate with the right sampling rate, then remux the content.

ISO IEC 14496-3:
Fix the muxer in order to correctly fill samplingFrequency (and/or extensionSamplingFrequency in case of AAC SBR) with the right sampling rate, then remux the content.

SMPTE ST 377-1:
Fix the muxer in order to correctly fill Audio sampling rate with the right sampling rate, then remux the content.

ISO IEC 23003-4:
Fix the encoder in order to correctly fill bsSampleRate with the right sampling rate, then reencode the content.
