from the last year lot of TV brand not support any more DTS(also passthrough) , it’s very nice to be have a transcoding DTS 5.1 to E-ac3/DD+ 5.1 (1664kbps) instead AAC without big diffirence of audio quality. ffmpeg support E-ac3 encoding with small CPU load. Thanks

Your logs show that you are playing DTS HD-MA 7.1. PMS cannot transcode 7.1 channel of DTS, only the core DTS 5.1 portion, so the best you can get is 5.1 channels. Your TV reports it supports 5.1 channels for AAC, AC3, and EAC3. For 5.1 channels, there is no noticeable quality using any of these …

thanks for your answer, but 5.1 AAC is not supported by HDMI ARC so TV downgrade to DD 5.1. So this is the problem: double conversion “on-the-fly” DTS(plex)->AAC(TV)->DD(HDMI ARC). So mine Suggestions is about New Feature :“Force transcoding to EAC3” ,so there is NOT “double” conversion “on-the-f…

[image] anon18523487: PMS is converting appropriately. If you prefer 5.1 EAC3 over 5.1 AAC, there is no way to force that, but as mentioned before, there should be no noticeable difference. There are any config file on plex server can be modify to Forced transcoding to EAC3? maybe editing wi…

[image] anon18523487: there is no way to force that I repeat.

Perhaps Plex could consider internally prioritizing (E)AC3 over multichannel AAC when transcoding for “living room” devices? There are more situations where (E)AC3 can be successfully passed through to the decoding device, while there are more situations where AAC may be 1) transcoded again, or 2) …

[image] Volts: Perhaps Plex could consider internally prioritizing (E)AC3 over multichannel AAC when transcoding for “living room” devices? But what happens if the receiver doesn’t support EAC3 but only AAC. You’d end up with the same issue. Or if the TV only supports EAC3 for passthrough b…

[image] anon18523487: But what happens if the receiver doesn’t support EAC3 but only AAC. You’d end up with the same issue. Agreed, it would. But that’s the reason for the suggestion. I don’t think there are any receivers that support AAC and not AC3. Passthrough for AAC is really rare, if…

[image] Volts: I don’t think there are any receivers that support AAC I don’t know about that, but almost every one should support 5.1 PCM and TVs should be able to decode 5.1 AAC to 5.1 PCM and send that so it should work without needing another conversion. In this case the TV did say it su…

[image] anon18523487: TVs should be able to decode 5.1 AAC to 5.1 PCM and send that Ah! That’s a happy outcome, but it’s only possible with eARC. Regular ARC is limited to 5.1 AC3 and 2.0 PCM. ARC doesn’t have enough bandwidth for 5.1 PCM. It’s not untrue that a TV can decode 5.1 AAC, but i…

I force AAC transcoding on my LG by turning off E-AC3 support in the Plex settings so the other way round is possible. This is because I get weird volume fluctuations when transcoding TrueHD->E-AC3. Why does this menu exist in the first place if the TVs are expected to properly report what formats …
