Cannot transcode AAC to AC3 in Kodi

by approachabler

So I have a Mi Box 4k with Sony HT-RT3 receiver, connected with the Toslink (SPDIF) cable. I came to know that Kodi can convert AAC (or any format) to AC3 on-the-fly. My receiver only supports AC3 through optical cable. All the right settings are on still the conversion is not happening for some reason.

  • Enabled passthrough

  • Number of channels 2.0

  • Enabled AC3 capable receiver

  • Enabled AC3 transcoding

  • Disabled DTS capable receiver

Local AAC files through Kodi, and audio from Youtube addon for Kodi still shows as LPCM in the receiver. What can be the problem?

Is it not because you've got number of channels set to 2.0? Optical can handle 2.0 LPCM, so it wouldn't need to transcode.

I don't use Kodi but I guess it wont transcode unless it needed to.

I could be wrong, but I think the point of the AC3 transcoding is to get 5.1 over optical to a receiver that doesn't support AAC. When uncompressed (PCM) is an option, it's better than any compressed option (AC3, AAC, etc)

Most content on YouTube is only 2ch.

Did you select the SPDIF option in mi box audio settings?
