It might be an obvious information for some, but I wanted to share it to everyone in case it might be useful;
From most information we can find online, including Qualcomm themselves, the aptX adaptive codec seems to be backward compatible with the aptX HD codec.
See here:
Qualcomm® aptX™ Adaptive | Bluetooth Audio Codec Technology
Powered by new audio codec technology, Qualcomm® aptX Adaptive ensures an instant sync for superior wireless listening over Bluetooth. Learn more.
www.aptx.com
https://www.qualcomm.com/media/documents/files/aptx-adaptive-product-brief.pdf
Or on xda:
AptX Adaptive is Qualcomm's new Bluetooth audio codec which compresses audio at a variable bitrate
Qualcomm just announced the smartest audio codec yet, aptX Adaptive, which gives Bluetooth devices an ability to have more consistent audio quality.
www.xda-developers.com
But it's not the case. It's been confirmed by the earbuds/earphones makers, the aptX adaptive codec itself isn't backward compatible with aptX HD codec. The earphone chipset has to support both aptX HD AND aptX adaptive for it to work.
Qualcomm QCC3040 based devices for instance don't support aptX HD, while being officially compatible with the aptX adaptive codec (as seen in the aptx official supported devices list).
Note that the chipset itself isn't officially compatible with the aptX adaptive codec, but from what SoundPeats told me, they are still making it work on it officially work with the help of Qualcomm.
What it means is that with phone not supporting aptX adaptive, for instance the Pixel phones, we can at best get the normal aptX.

I've been trying to find out what the DAC is in the Shield Tablet and if it will support high resolution audio but there is nothing on Nvidia's site and any audio related search just goes on about the speakers.
I'm going to load up some 192KHz/24bit FLAC files and see how it goes. Looks like it supports most formats but there is no mention anywhere of high resolution audio support. I hope if does not down sample.
Anyone have any experience?

In same position, not much info to find about the DAC. My main usage plan is as car dashboard tablet, so i don't want to go all audiophile and guess i have to see how it will play out. Else i will probably just end up investing in a proper HDMI de-embedder.
It would however be nice to know just a little about the DAC.
It won't support high-res audio because Android doesn't, it'll resample everything to 48Khz, regardless of the capability of the DAC. The only exceptions are devices where the manufacturer has added support for it, from memory only LG and Samsung to date. If you want HD audio get a USB DAC and use USB Audio Player PRO (UAPP). I use my Dragonfly 1.2 with my Note 4 and Shield Tablet, it'll do high-res via UAPP (or Hiby or Onkyo music players, I prefer UAPP). Personally I have no need for HD audio, but the external DAC and amp runs rings around the audio quality and amplifier grunt in tablets and phones.
Hello XZP land!
I've had mine for a while (since launch actually), and I really love the device. However, I've come upon a conundrum that I think needs some technical elbow grease (which I am not skilled to do).
I own some Hi Res audio, and my favorite player (Neutron), as well as some others, supports playback of it. The thing is, the XZP doesn't show as having the ability to, according to this Neutron thread on the matter Hi Res in Neutron. Our devices currently do not offer the Hi-Res options.
Qualcomm on their site for our chipset says;
Developed by an audio technology leader, Qualcomm Aqstic audio codec (WCD 9340/9341) supports high-resolution standards that recording studios use to master tracks, creating a pure audiophile listening experience. It has an integrated DAC (digital-to-analog converter) that supports native Direct-Stream Digital (DSD) and pulse-code modulation (PCM) Hi-Fi audio playback. DSD is a standard found on Super Audio Compact Discs (SACDs), and the Qualcomm Aqstic audio codec can decode DSD files natively. The DAC on the Qualcomm Aqstic codec has ultra-low Total Harmonic Distortion plus Noise (THD+N), which means no additional noise or signal is added for the most authentic sound reproduction. The Qualcomm Aqstic codec is also designed to give you the highest dynamic range available, so you can feel the dramatic change of volume and emotion in your favorite music.
SO I know the chipset can do it.
Now, Sony provided us with the "DSEE HX" quality audio setting... and it says "upgrade quality of compressed music files to 'NEAR' Hi Res'". Meh, okay, so you can muck around with compressed files and make em sound better. I don't believe that resolves my issue, and enables anything firmware wise.
I believe this means we need to enable the feature via firmware and bypass Sony's attempt at audio features in their DRM space. Has anyone been able to enable this in Neutron? How's your Hi-Res playback?

Why not just use the stock Sony music player for hi res playback? Hi res audio files have been supported since the Z2 and onwards. You can just use the Sony music player for hi res and neutron for everything else. I think that its auto enabled by default within the Sony music player. When you see the "HR" logo on the album art I suppose that means its enabled.
If your trying to enable the same thing in neutron and it doesnt work because theres a toggle. Id blame the creators of the app or simply Google for the lack of support. It can be one of 2 things stopping it from working for you. The android os or the app itself. I dont use neutron personally and never have. Ive always used the Sony one after I gave up on poweramp. I wouldnt blame the device itself. Its just like my issue of vulkan support whereby apps cant see that the device does support it. In that case I would blame Google. This is as much help as I can offer.
Hi-Res is enabled out of the box with the in-built Sony Music application and contrary to what RJASSI21 said, the HR logo does not appear on all Hi-Res audio tracks album art, only on 24bit Hi-Res tracks album art and I have been using Hi-Res audio on my Z5P and my XZP but I have only ever used the Walkman/Music app provided by Sony and it works.

Thanks to both of you for the info. I am going to see if I can get the Neutron dev to add the libraries or whatever's needed to get that app where I want it.

Much appreciated! I was looking for these Neutron settings on the XZP too since they were n my LG V10 (before it died on me last week). Neutron music player has been my go to player for several years now so here's hoping we get some positive updates soon.
Thank you!
There was an update to Neutron for Oreo support yesterday and now I can finally see the Hi-Res Codec and Hi-Res Speaker options.
The new Dali IO Bluetooth headphones support Aptx HD but I don't think the Note 10 and other Samsung devices only support Aptx AAC and LDAC. Has anyone found a solution to this?

You are right, still no support for aptx hd. N9 doesn't have it either.

What does it list on Developer options?

SBC, aptx, AAC and LDAC. Then also option for ' other codecs' and 'scalable codecs'.

Hopefully they add it on Android 10. Oneplus added more codecs on Android 10.
Now with Aptx TWS+Audio. Which obviously came as part of software update.
Hello,
I’ve installed GMS and it’s working perfectly to know that my aptX headphones doesn’t work because it’s a codec from Qualcomm which was banned too. (I’ve enabled Developer’s option as the screenshot attached)
Now it’s running with AAC, SBC codec only which i feel a much differences from aptX.
Anybody has a suggestion how to install the aptX codecs manually?
Thanks,
Seree

LDAC?????
Enviado desde mi Pixel 2 XL mediante Tapatalk
I believe that this would be done thru a custom recovery unfortunately....
I also think Dolby has something to do with the chip that is compatible with that codec. Dolby = American.
UPDATED: I can’t find a method to install aptX into my Mate 30 Pro so I just bought Fiio Q5S to connect with my Mate through HWA/LDAC and very happy with the sound now!
Can anybody help me? I use Sony's WH1000XM3 headphones and by no means can I set LDAC audio codec. There's only AAC available for me. Why?
Go into developer options and find Bluetooth codec option, there you can select LDAC.
