Hi all, got a question that I hope people can help with. I have an older sound system where the only digital input is via TOSLINK (optical) that can only decode Dolby Digital (not plus) and DTS. Would it be possible to pass digital audio out of this Chromecast (possibly downmixing audio like DD+, DTS-HD, Atoms) and what's the best way to go about it?
The GCCWGTV does not have a Dolby decoder, it wont transcode DD+ to DD (which then has to be converted from HDMI to Optical for your scenario).It does, but it only outputs 2 channels via the TOSLINK output. I was wondering if it would be possible to directly output the HD audio to my AVR, possibly even down-mixing DD+ to DD. What would be a good device for it? I see some on Amazon but I'd appreciate if people had their experience.
If you want access to all apps 5.1 output (especially those using DD+) you'd need an HDMI>Optical extractor that also transcode/converts DD+ to DD (includes a Dolby decoder), which are more expensive and harder to find: e.g. @ $80 - HDMI 2.0 Audio Extractor Converter with Downmix [JTECH-EXD2] - J-Tech Digital
In terms of 4K/HDR streamers that have Dolby decoders (and transcode DD+ to DD), the FS4K (and any other more recent non-Lite Fire TV model), the TS4K, the Roku Ultra 2020, the Shield/Shield Pro, and the ATV4K all fit the bill, so you wouldnt need a more expensive extractor/decoder/converter (such as the one above)., but just an extractor/converter:
@ $50 J-Tech Digital 4K60HZ HDMI Audio Extractor/Converter SPDIF/3.5MM
@ $35 HDMI Audio Extractor [email protected] - J-Tech Digital
(The difference being one supports 4K60 and the other 4K30 passthrough, and you can find each for $10-15 cheaper on Amazon).
The cheapest alternative streamer with Dolby decoding would be the FS4K @ $40 (ignore the TS4K - its Dolby decoder is broken), the most expensive would be the Shield Pro/ATV4K @ $180-200.
Considering the GCCWGTV+Extractor/decoder/converter = $130, whereas the FS4K+Exctractor/converter = $75, that might make a difference in terms of purchase decisions.
