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.

Anyone know the DAC chip used in the HTC Fuze? Am curious what the maximum audio resolution file it can handle. Many thanks.
Enjoy the Music,
Steven
The CD has a 16bit audio resolution sampled by 44100Hz and full stereo. I think,that all 2000+ devices running 200mhz+ processors performs not less than 25years old technology. Is it not enough for you? For me it is.

Thanks for the Redbook specification on CD. Back to the original question, does anyone know the DAC specification on the Fuze?
Raphael is not CD player. It has its own audio device and who knows how it decodes mp3s or "optimizes" the playback

Eactly, i am curious to the audio chipset used in the Fuze and that helps to develop/know what codecs might be employed. Looks like i'll have to ask HTC directly, though was hoping someone here knew. Many thanks.
I know it is a bit overkill for a tablet, but considering X1's performance (same gpu,just more cores), it would be nice to know if the K1 can passthrough Hd audio via it's hdmi port.
Anyone tried ?
HI there! I'm very sorry but I wasn't active in this forum at XDA before now. I've been experimenting with this topic for some time now.
YES, The Shield tablets (regardless of versions) can passthrough bit-perfect sound, both stereo or 5.1 (and higher, depending on your stereo equipment).
So here's the deal:
1. You'll need an HDMI audio extractor. I recommend Monoprice's HDMI audio extractors, although there are slightly less expensive models out there, you can't really trust their specs.
2. A standard HDMI audio extractor can passthrough both digital (coaxial or TOSLINK S/PDIF) or digital-to-analog out. For surround sound you'll want an HDMI audio extractor with surround sound outputs.
Essentially it comes down to the media player you'll be using.
I've tested MX Player (with the custom codec loaded), VLC Player for Android, and Kodi. All can do passthrough IF you're using an HDMI extractor that will be identified as such (stereo-only or surround-sound capable) via HDMI. This critical.
Older versions of Kodi they called the "****ty" builds used LPCM bit-hacking to force a passthrough via HDMI. Newer releases require that a HDMI device handshake occurs so the media player will allow an appropriate passthrough to occur.
Unless you will be playing .MP4 files w/ 5.1 surround sound, I recommend MX Player for most music and video files. Passthrough works well on it when set up correctly. VLC is ok too, but the interface leaves something to be desired in my opinion.
Kodi can decode/passthrough 5.1 and higher via HDMI from .MP4 and other files although the user interface is less simplistic.
Hi -
I know that Android these days has relatively decent USB audio support, when connecting an external DAC.
On the Google Pixel I'm connecting a Fiio Q1 external DAC and sometimes it skips in songs, as if it's a scratched CD, when playing through Spotify. I know there is an app (USB Audio Player Pro) which will provide proper support for playing audio through an external DAC, but only if you use that app as the player. So will not work when streaming from services such as Spotify.
I believe this is mainly due to sample rate conversion, which apparently Android does by default, instead of matching the actual sample rate (e.g. 44.1 KHz CD quality will get upsampled to 48 KHz, an unnecessary step).
Is there a way to get better support, perhaps through modding the stock ROM, or installing a custom ROM? Is this a kernel issue? Or a ROM issue?
Thanks.

About the Android sample rate conversion I think there's no solution for now, just let Google do their job.
By the way, I'm using HTC type-c to 3.5 jack cable, it has a DAC, works fine here, no "scratches".
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.
Hi all,
New to the forums, wonder if anyone could help?
(Have had a search but not able to find a definitive answer, apologies if I've missed something)
Does anyone know if there is a way (custom rom/sideload etc) to enable DTS (inc DTS-X/HD) as well as other audio formats to be passed-through on the Amazon Fire Stick or Cube?
Reason I'm asking is that I have a surround Samsung soundbar which is capable of decoding pretty much all of the audio sources chucked at it (Atmos, DTS, Lossless versions of these etc) and I'd like a cost effective way to stream videos with these audio types in them.
Conscious that the Fire (stick/cube) out of the box doesn't support DTS. I've looked at the Nvidia Shield and ATV4K but the Fire is quite a bit cheaper.
I plan to use Plex or something similar to host the media.
Many Thanks
