    OpenWebIf -- no audio in transcoded streams if channel contains AC-3 audio

    Hello,
    in OpenWebIf are two kinds of streams. Direct and transcoded. The direct ones work pretty well, including AC-3 audio. But trancoded drops AC-3 audio and physically transmits video only.
    Also I found that TV channels with AAC audio (already!) are again recompressed to AAC (with higher bitrate than original). I think it's a waste of computational resources to transcode content to same media format while introducing more compression artifacts in the audio.
    Is there any switch to keep the original audio in transcoded streams? I mean a passthrough or remux from original. I think it would help with AC-3 audio issue.
    Maybe the OpenATV system is missing transcoder from AC-3 to AAC?

    I am using openatv-6.3-hitube4k-20200206_usb image without any configuration changes.

    Same question here.
    Is it possible to keep all audio passed through without recompression and other info like subtitles and epg passed through?

    I have another box, but the same problem . no audio on transcoded stream
    tried the audio setting: aac,aac+,mpg and mp3. I never get audio.

    using openatv-6.2-revo4k-20190817_usb

    this occurs on hd channels with ac3
    sd channels with mpg sound no problems
