I upgraded my Z1000 Pro to a Z2000 Pro. First thought it is much faster, the 1000 was fine but slow… But I have one big problem with the 2000. For Audio I have a Sonos ARC System which supports Dolby Atmos with Dolby True HD but does only support DTS. No DTS-X and no DTS-HD. In the settings of the 1000 it was possible to downsample DTS but not downsample any Dolby content. This worked great. In the settings of the 2000, I can‘t find this option. Does somebody know if it is just hidden somewhere or if there is another solution? Thank you.
I am experiencing the same issue and would like to ask if you have found a solution in the meantime. My setup is as follows: z2600 Pro -> Panasonic JZW1004 with HDMI eARC -> Sonos ARC The firmware version of the media player is 1.0.95. When playing movies with DTS-HD Master Audio and DTS:X soundtracks, the soundbar remains silent in the HDMI audio settings RAW and Auto. With Downsampling enabled, the soundbar plays DTS 5.1 audio. However, this setting has the disadvantage of also downmixing Dolby Atmos TrueHD soundtracks, which is not desired, as the soundbar supports this format. The Sonos ARC cannot play lossless DTS formats. However, when I play Blu-rays with DTS HD 7.1 audio and set the player’s audio output to Bitstream, the soundbar has no issue playing the DTS 5.1 core of the audio stream. I therefore assume that the Panasonic TV, despite not being advertised for it, supports passthrough for lossless DTS formats. I’ve already experimented with a custom EDID file, but that didn’t solve the problem either.
If you post your EDID I can add DTS (not DTS-HD) and see what that does. But if the BluRay player outputs DTS core then it must be receiving an EDID with DTS enabled.
Thank you for your reply. Here is the EDID file exported from my player. I used the AW EDID Editor tool to add a section for DTS-HD under the Audio Block and set the following values. Audio Format: DTS-HD Max Number of Channels: 8 Sampling Frequency: 44, 48, 88, 96, 176, 192 kHz Audio Format Code Dependant: 3 When using the modified EDID file, the soundbar remained silent, and the Sonos app displayed "Unsupported TV audio" when playing a movie with a DTS-HD 7.1 audio track.
Ok - just realised - there was a bug in the old Z9X that came to light recently where if the EDID only contains DTS and not DTS-HD, the box still outputs DTS-HD. Just tested on a BPD box and the same thing happens unfortunately. I think it was probably overlooked because it's very unusual to have a processor that supports DTS and not DTS-HD these days. The workaround is to press the Audio button and select the DTS core track there.
Thank you for your proposed solution. That approach works when audio tracks are available in different resolutions. However, some movies offer only a second track in Dolby Digital Plus 5.1 alongside a DTS-HD audio track. In such cases, the downmix from DTS-HD to DTS via the "HD-Audio Downmix" option provides a better-quality result. The Z2600 is my first media player from Zidoo. According to forum posts, it was (or still is) possible with older models to configure the downmix for HD audio formats separately for Dolby and DTS. Do you know why the firmware of newer devices doesn’t offer separate adjustments? Users who stream ripped movies are not the primary target audience for Sonos. As a result, the manufacturer has chosen not to license lossless DTS formats and instead prioritizes Dolby formats. If I am correctly informed, lossy DTS 5.1 was only supported once the patent protection had expired.
Yes, the older 1619DR models (and newer AML models) support separate Dolby & DTS downmixing to core tracks. Again probably overlooked on the BPD models. However, TrueHD doesn't really have a core track - it uses a separate AC3 track, so assuming you've only ripped the TrueHD track, you can set Downmix to On in the BPD models and it will play Core DTS (because that's built into the DTS-HD track) and TrueHD because it has no Core. I don't think there's any excuse for Sonos leaving DTS-HD out - what about BluRay players? The only possible reason to leave it out is cost. DTS has to be licenced, even to bitstream, and there's an inherent cost in that, usually in the choice of SOC.
