Hi, In have searched a bit but can't find any conclusive info,

Is the akm DAC working in Lineage?

I just tried nuclear rom, and it wasn't working (through universal audio player)

I assume that means it's not working on lineage either?

Unless I missed some way turned it on...

//// OK, in the AICP thread someone clearly stated that no custom ROMs have the dac working, since the drivers haven't been released or something. Maybe it should be stated on first page? It says audio working, which might be misleading. Esp since many people buy this phone for the dac.

So I've downloaded all axon7 official lineage builds and extracted the boot.img, they are all identical. So I guess I need a different kernel. Right?

This one is only alpha but the title of the post says its for LOS 14.1

I'm curious about the hi-fi recording/microphone on LineageOS. How is it? As the Global team (A2017G) broke the hi-fi recording (currently fixed by the devs, they switched the call mic and hi-fi mic by accident).

From experience I know that CM/LineageOS builds (for all devices) don't have a good microphone when recording video or audio with a recorder app.

If the microphone could be as good as stock I'd consider LOS again (currenlty beta testing for A2017G tho)

I want it for the exact same reasons you do. Did it work?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Teet1:
Yes! Although with the soundfix, with dolby atmos alone it does sound a little more muddy/compressed compared to stock as if the mids are too high. So just flash viper4arise as well and mess with the speaker or headset equalizer to your liking
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] sToRm1nG:
Is it still necessary to flash the universal bootloader? I am asking because the A2017G now has a 7.1.1 bootloader. Or won't this work because of the A2017U blobs?

I am planning to switch to LOS and thought it might be enough to just start from V1.2.0B02 without flashing another modem and bootloader.

Did anyone already try this? If not I will probably go ahead and try it myself.

[MENTION=4911249]Unjustified Dev[/MENTION]

I guess I will try it without the universal bootloader and get back to you if it is working (starting point will be V1.2.0B02).

I will also add the new TZ version from V1.2.0B02 (TZ.BF.4.0.1-00325).

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] sToRm1nG:
It did not yet work (SIM not recognized and com.android.phone constantly crashing). :p

I am reverting to stock to update to V1.2.0B01 since this is using the same TZ as the one in the official nightlies (I guess the images in B02 are not compatible).

I will let you know as soon as I tested it.

*EDIT*

My self compilled ROMs did not work (I guess I patched to much stuff, will probably re-sync the complete source). [MENTION=3883465]dedors[/MENTION] I recommend downgrading to V1.2.0B01 since this wont need any change to the phone at all (trustzone).

The only weird thing is that during boot the device is not properly recognized by Windows (Unknown USB device - error while requesting a device description).

Otherwise you will have to edit the updater-script and add the new trustzone.

*EDIT2*

Yeah, USB seems to be broken. Only charging is possible.

Hello everyone! Please, I need your help. I am facing serious problems with Wifi after installing LOS. I also recorded a video of the problem. It turns out that he disconnects all the time and does not let me do simple tasks like downloading apps from the Play Store or playing games online. I would like to know if someone has a similar situation, because I do not know what to do, I have only the alternative to break this phone lol. Please, any help is welcome.

Problem:

https://www.youtube.com/watch?v=xhrHhwUx_O0&t=3s

I solved this problem as follows: I went into the developer settings and deactivated "USB debugging", and activated again. After rebooting the device with USB connected to the PC and there Root did the boot (I do not know if it had something to do with this) and when I started the system he gave me the options of the image below. I hope it works out for you too. Greetings.

Hello everyone. I have some problems with wifi tethering. Devices that try to connect do not get IP unless I disable and reactivate the sharing. And when a device is connected, I lose the LTE and the bit rates are zero and when I disable the wifi tethering, wifi don't work as well. I have a a2017g with the last build of lineage.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] tele_jas:
I have the same problem with battery life, but this ROM is everything I want, so I'm willing to throw it on the charger a little more and hope the battery improves with builds, over time. I easily got 6+ hours SOT on stock.... I'm lucky if I reach 4 on LOs. But this is about on-par with my old Nexus 6P, which usually still gets me through the day.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] joe187xx:
I have the 2017u and been having issues with tethering too but i dont lose lte , when i turn it on and do a speed test on the phone its self the speeds are normal but whatever connects to this phone has extremely low speeds like unusable, and its not just this rom its the same on RR and the nuclear rom as well. I go back to stock and everything is fine so idk whats going on. I tried multiple clean installs , tried the universal bootloader and modem like recommend and i tried the stock N boot and modem for 7.0 and .7.1 its all the same outcome. Something is limiting the speed for connected devices. Other then that everything else has been great, battery life for me has been better then stock.

I am getting massive lags with stock kernel.

when playing music i get some stutters, but not all the time, when typing I get lags up to 2 seconds! while sometimes its completely fine.

Fresh booted its fine again.

Last weeks nightly with full wipe.

I know with an other kernel probably fixes it, but it should never be that worse with stock kernel.

Edit: after reboot it took me 90min while listening to music (via BT), and it just started stuttering pretty hard, like unusable. keeping display on for a while makes it better, but its still here.

Edit2: radio active kernel, same problem. no replys to this topic. Either this is a too well known problem, or its "me" specific. In case its the obvious second, how do I track down the problem? All I get to see is that lineageOS system, google play services and android OS use quite some CPU time.

Same here. I noticed that if you change the preferred network type (under mobile network settings) to prefer WCDMA/GSM only, the hotspot speeds increase. When tethering with LTE, I get 0.15 mbps, whereas that jumps up to 6-7mbps using WCDMA.

Any idea what might be limiting LTE tether speeds? Changing to WCDMA is a temporary fix to gain some speed, but it's not ideal.

So because of missing Quick Charge and veery slow charging I flashed RR's boot.img with newest TRWP as image to boot.. Well, bootloop.. So I restored my boot backup and I could boot normally again with slow charge. I've tried older boot.img's from older LOS builds with no difference either.

I'd really like Quick Charge, because I have to recharge my phone once a day and charging it over 4 hours is difficult during the day. I've had people tell me Quick Charge on RR works, so I'm irritated..
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] BlackAfghan:
Are you sure Quick Charge isn't working? There seems to be a problem with normal USB charging, i.e. that it most of the time only uses 500mA instead of 1000mA. But sometimes it works..

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] eMadman:
I have noticed that the volume control on my device has never been a consistent/gradual increase/decrease since switching to Lineage OS.

Specifically, if the volume almost doubles when I go from 3 clicks up from 0 to the 4th click. I have very sensitive headphones and 3 clicks is too low, 4 is very high but manageable but not for extended periods of time. From 4-5, the shift is gradual again.

You clearly have not used the forum search feature. Try that before asking your extremely easy to find answer to question.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] eMadman:
The curves seem easy enough to figure out, however, i'm not sure WHICH stream types I should be editing for this specifically. The headphones I tested with are actually low-impedence wired in-ear headphones and connected to a bluetooth amplifier/headset combination.

Looking at this chart, copying/pasting my earpiece settings over to headset MIGHT do the job... although, the Audio_Stream_Music field is looking for "Default_media_volume_curve which I'm not seeing in this XML file anywhere.

I think the best approach might be to copy this from the stock axon 7 rom. I noticed Google has this available in their marlin source code. Is there a way I can get access to that without switching back to stock? I'm not seeing it in the kernel source code from ZTE's site.

[MENTION=4834450]eMadman[/MENTION] - Does this help? Straight from stock nougat on the A2017U.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] eMadman:
Some minor differences between the two, but nothing huge. I've swapped the files and restarted my phone. I have the same issue with volume controls.

The LineageOS file has no defined curve for music. All devices call a "Default_media_volume_curve". Not knowing what that is, I defined a curve to the headset for music, copying what the stock file had for earpieces in that space.:

<volume stream="AUDIO_STREAM_MUSIC" deviceCategory="DEVICE_CATEGORY_HEADSET"/>
<point>1,-4950</point>
<point>33,-3350</point>
<point>66,-1700</point>
<point>100,0</point>
</volume>

Also interesting. I don't know what this is:

<volume stream="AUDIO_STREAM_BLUETOOTH_SCO" deviceCategory="DEVICE_CATEGORY_HEADSET">

So... basically, that didn't do anything for what I'm trying to do. It still spikes heavily when I move from 3-4 on the bluetooth device. If I plug the same headphones into my phone directly, I see a smooth transition across the volume range. I don't think it's because of this file now.

One thing Lineage is doing differently from Stock is that it's linked the volume control on the bluetooth pod to the OS's volume control. In stock, the two controls were independent. Lineage was behaving as my master volume while the volume control on the bluetooth pod was behaving as a volume dial on an amplifier. This is implemented differently in different phones. My old Sony Z3c did the same as LOS until it got the upgrade to Marshmallow, when it started seeing them as two separate volume controls. The difference being that the old phone still had a smooth volume curve on bluetooth.

I've attached my slightly modified stock file.
