Details about the DAC in 7T - OnePlus 7T Questions & Answers

Guys, do you know the detailed information about the DAC used in our OnePlus 7T of the audio passes through the Type C » 3.5mm adapter? Like dynamic range, impedance it can handle, etc.
Please check the LG G7's specs in this link : https://m.gsmarena.com/lg_g7_thinq-9115.php . In Sound section there's it's sound specification written in Bit and kHz. Also, since the 7T has Qualcomm Snapdragon 855+, which DAC chipset model does it have?

This is what our chipset is using for audio. As for USBC to 3.5mm jack, nothing too special going on but you can look on Amazon for the hidiz adapter which claims to have a dac integration. I haven't had the chance to get one yet.

Just to add to this, I tried the samsung dongle(believe passive) that came with my tablet and didn't work.
My SMSL Idea dac works fine set up as usb-audio 1.1. As does my veclan odessey hd.

I just ordered the Tempotec Sonata HD Pro. I was planning to buy the original OnePlus adapter but since I want to use it with my PC also I went for the separate DAC device. Anyways thanks for the replies ??
Sent from my OnePlus7T using XDA Labs

Has anyone any clarity over whether our 7t's have analog pass-through for the usb-c port? I.E. uses onboard DAC for passthrough? Any reviews for quality vs external DAC usb-c to 3.5mm adapters like ESS/Realtek?

[Q] USB Audio Out?

Can anyone who owns the G3 confirm that USB Audio Out (over an OTG cable) works through a DAC? I can't seem to find any information that confirms or discounts that this works.
Thanks!

It does work with my Fiio E17. Just tried it today after almost buying an app that was supposed to do so. My only complaint is that the DAC seems to be charging while connected to the G3.

Thanks, Jesadac! That's great news... I was hoping this was the case, as I believe the G2 also supported it.
I assume you're referring to the USB Audio Player Pro app? It truly doesn't replace the native ability to have a clean digital audio out signal for all sounds out of the phone.
I have the Fiio E18 and a friend has the VZW G3. We just tested the combo and it seems to work fine.

Just bought the new Cayin C5 DAC/Amp. My TMo LG G3 does not put audio out though the amp when connected via OTG. It registers it's connected I'm guessing because all audio is no longer played through the phone. Plugged into my friends Note 4 and it worked right away. Is this is G3 problem? We're both on Lollipop.
I know this is an old thread... but do I still need USB Audio Player Pro to get USB DAC to work? I thought Android 5.0+ brings USB audio, and right now my Beyerdynamic A100 doesn't work by "simply" plugging it in... however I do get about half second of audio and quits.
I go on LG G3 with app USB Audio Player PRO and HibyMusic app, my DAC is Hegel HD2 and DragonFly RED. Logitech USB headphones works too. with China OTG cable.
I can confirm Spotify and youtube doesn't play audio through usb (android 5.1.1), and it still mutes integrated speaker when connected:silly:. Must have usb-player i guess.

Compatible USB DAC/Amp?

Hi, I've found that the headphone output of this phone, while good for some headphones, has too much noise for sensitive IEMs and not enough power for some less efficient headphones, so I'm looking into a portable DAC/Amp. I tried this one with a USB-C adapter:
https://smile.amazon.com/gp/product/B00FJSEAZ4
But it didn't work. I know the USB-C adapter works, as I've used it with a thumb drive, and I know the DAC works on other Android devices, but apparently compatibility isn't universal. So has anyone successfully tried a portable DAC with this phone?
My Fiio Q1 works fine with the phone.

Thanks, that's good to hear. I was considering one of Fiio's products
I tried this one: http://hifimediy.com/android-dac
Works very well together with an USB B to C converter that supports USB OTG and drove even my good old 600 Ohm AKG K 141 loud enough!
It has a Sabre DAC. Bought it out of concern that the sound of the phone might not be good enough. But it is - at least with low impedance headphones like my Ultimate Ears UE 10 TF I don't find a difference to the 180 $ sony walkman of my GF.
(Small remark: Used a Samsung USB B to C converter first. This one, while doing very well on the PC and with ADB and also with the charger did not work as OTG adaptor.)

Weird, that's the exact one I tried that didn't work. Maybe I needed a different USB-C OTG adapter

For sure. It works for me without problems - plug and play.
I use this adaptor: http://www.delock.com/produkte/G_65678/merkmale.html
Side note: While I could use the Samsung adaptor for charging (but not for OTG devices) this one works well for OTG - but not for charging.
Edit: The price for te DAC on the amazon side is way higher than if you buy directly from the Hifimediy website.
And you should also note, that this DAC while it's pretty good for higher impedance phones did not work well with my low (32 ohm) impedance IEM's. But for those I found no need to use the DAC.
I ended up with a Fiio E18, I like the fact that it has playback control, plus B&H has it on sale right now. It doesn't seem to work with Poweramp, but it works perfectly with USB Audio Player PRO.

Will USB Audio Player read OTG storage?
Most file explorers do not see mnt/media_rw/0EB0-0FF. Do any players?
Quick, and hopefully not too stupid, question, do I need to root the phone to get the DAC working with Google Play Music?

Does the 24-Bit THX Certified DAC adapter work for other phone as well?

Does the 24-Bit THX Certified DAC adapter work for other phone as well?
We plugged it into an S8 and OnePlus 3t and it did output sound from both. No idea if there is any software needed to control the DAC or not, although I would assume not.
Thanks for the feedback...thinking to get one for mate 10 pro...
it should work fine with any phone as it uses the digital audio out pins of usb-c. its decently priced and much louder than most. i found a cheap LG G5 hi fi sound module that is also brilliant.

ote 10 and + usb-adaptor dongles 3.5 audio

This video may help re audio dongles and USB-C adapters
It's easy. The note 10 and plus will work with any USB C to 3.5.mm adapter that has a built in DAC. The ones that don't only work with phones that have a built in headphone DAC. The N10 and Plus doesn't.
Yes but the huawei salesmen said there's will work and many advertiser claiming they have DAC built in
As I said if the dongle has a built in DAC it will work on the N10. If not it wont

Question USB C to 3.5mm Headphone and Charger Adapter that works on Pixel 6 Pro

Has anyone managed to find a USB C to 3.5mm Headphone and Charger Adapter 2in1 for the Pixel 6 Pro. The few I have tried so far only at best will work the audio port but none will charge. Hoping to find one that does both for when driving to be able to charge and listen to music with the 3,5 mm headphone attached to my car radio input. Adapters similar to the attached images that work would be ideal.
Thanks
Unfortunately, the only ones I've seen that reputably work for Power Delivery phones are effectively "hubs", like Anker USB C Hub, PowerExpand 11-in-1 USB C Hub Adapter, with [email protected] HDMI and DP, 100W Power Delivery, USB-C and 3 USB-A Data Ports, 1 Gbps Ethernet, 3.5mm Audio, microSD and SD Card Reader (sold out on Anker's site PowerExpand 11-in-1 USB-C PD Hub). They make other hubs, but I don't see any others of theirs that have a 3.5mm headphone port.
I too, wouldn't mind a more compact and cheaper solution, but I no longer really care about 3.5mm headphone jacks and would be happy with a similar adapter with two USB-C ports - one for USB-C headphones and the other for charging. I may have seen some like that too but not sure as to their reputation, and overall it's not that important to me.
Might be a logic glitch where it assumes that having a usb "device" plugged in means that the phone needs to supply the power rather than receive it.
Does your car radio really not have bluetooth?
And since you are in a car, how about a Qi charger pad?
you would need

Unfortunaetly it doesnt have bluetooth and since I use the phone for navigation while driveing the Qi charger woldnt really serve a purpose.
Is there a difference between the technology in a pixel 4a5g and the Pixel 6 pro. A device like the first picture I showed works fine in the pixel 4a5g but only does audio and no charging for the Pixel 6 pro

I use a magnetic Qi charger on my dashboard. It works great and provide plenty of power to charge under heavy use. Not as elegant as a proper split USB adapter, but should at least work if you can't find one.

Why would he want to use Bluetooth? There's still reason not to. Not many car stereos support the higher quality Bluetooth streaming codecs. Not even AAC, I know mine doesn't. SBC is very unusable.

I drive a Toyota Corolla it doesn't have audiophile speakers and I can tell the difference it is night and day even when streaming Amazon music although it's less of a difference there but if you're listening to compressed music on YouTube music there is a difference maybe you should go get your hearing checked
i mean youtube music starts at 48kbps aac to 256kbps
amazon songs start at up to 867kbps and over 3k kbps peak for premium
unironically searched it up someone made a patch that enables SBC to go up to its maximum bitrate of 512kb
stereo that makes it onpar/better with aptx and works sending to older devices like car stereos
he even pushed it to google 2 years ago buts its still processing

its in custom roms like RR etc shame its not implemented in stock still
You should look into a Bluetooth DAC. Yes it's another thing to charge but for me it's the best of both worlds, quality wired sound yet not tethered to the phone or whatever device. I have a FiiO BTR3K. It's super small, I connect it to a belt loop, and it's got 10 hours of battery life. And yes, you could wire charge your phone while listening.

I feel like there will still be some degradation in the signal because it is still transcoding a lossy codec to another lossy codec. It's something I'll try when I'm connected to my home stereo.

Anyone who tells you they can tell the difference between bluetooth and {insert whateverthefeckhere} when competing with engine, road, and wind noise is absolutely full of sh**. Your ears are not that sensitive.

I don't understand this logic. The phone doesn't turn off when you use Qi. It still works. If its about how the phone is mounted, either buy a holder with a Qi pad in it, or stick a Qi pad at the back of the holder.

Go get your hearing checked then because there is a difference. It's less of a difference when using tidal or Amazon music but when using YouTube music or Spotify etc it's staggering.
