Getting call audio issues as well, one way depending on headset or speaker. Also now y ringtones aren't working, everything says unknown ringtone and the only selection is none, won't let me switch. Think this is the end of this ROM for me. Seems really half baked.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] tdm:
Certainly there are call audio issues, this has been covered throughout the thread. Obviously u-dev is not able to fix the issues or he would have long ago. I may be getting atmos working soon, as I have both the axon7 and the axon7mini. They both have similar audio setups and they both ship atmos stock. But no promises.

As for ringtones, I haven't ever heard of any issues with them.

But by all means, if you want to ***** and leave, go for it. Don't let the door hit you on the way out.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bmckenna:
Sorry, I didn't pore over the entirety of the 380 page thread before installing. I checked to see bluetooth listed under "working" and assumed that was enough to actually yanno, get bluetooth audio on phone/Hangouts calls using a relatively high market share headset (BeatsX).

I'm just disappointed this is the first time I've done a custom ROM...going back through the same processes on a G3, Nexus 5, Galaxy Nexus, and DroidX...where the end result really felt unfinished and there were big usability gaps, and some of those devices were modded within just a few months of purchase...this device has been out what, over a year now. Pretty much everything I've used from GN forward was CM vein as well so...was just expecting a little more cutting edge with a little less blood. I know, the FP disclaimers, etc. but still, just was a subpar experience compared to the other times I've flashed anything custom on a phone. Every other time has been an increase in net usability from stock ROM, this was the first time it was not.

The ringtone issue was certainly odd. I rebooted a few times with no success in being able to change it. I wound up trying to flash another ROM to see if it was better (wouldn't boot, though I didn't try to troubleshoot very long) and restored back to a TWRP backup I did on Lineage...after fixing the "Wrong PIN" issue by deleting the db files, I'm able to change my ringtone/notification tone, but the alarm tones seem to be missing a bunch of default tones that were there immediately after installing the ROM. The only thing I can think that really would've done anything to resolve through that whole process (since I restored system/data partitions) was clearing cache during the restoration process in TWRP.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] tdm:
[MENTION=419509]bmckenna[/MENTION] ...

To be perfectly honest, I don't use my axon7 much anymore, as I have been bringing up the axon7mini for the past several weeks. And prior to that I had run AOKP on it, not Lineage (though they are nearly identical). And comparing to stock is meaningless to me because I haven't run stock on any device in the past 5+ years any longer than necessary to root, backup the partitions, and start hacking on a device tree. But from my experience and judging from others' posts here, Lineage 14.1 is working pretty well aside from a couple of audio quirks. Certainly very usable for a daily ROM.

Regarding BT audio, I have a pair of LG BT headphones (HBS 700 or somesuch) and a couple other BT devices. They all work fine. The phone pairs and works with my car (older BMW) perfectly.

I really don't know about why you had such a poor experience or what's up with the ringtones. I'd suggest a fresh install without any add-ons and see how it goes. If you encounter major issues, I'll certainly try to repro them and fix them. Deal?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jawz101:
[MENTION=419509]bmckenna[/MENTION] I just got done switching from LineageOS, to stock, and back to LineageOS again and experienced no issues with missing audio files.

I have about 6 various Bluetooth devices and they all work fine (ear buds, speakers, car stereo, laptop, smart watch, etc.)

As for restoring data and system partitions- I would think whatever your problems have been would've been because of that. At some point I don't think it's good to mix and match partitions from one ROM to another. As much as they're separate partitions there's just bits and pieces from system that find their way depending on data for a particular ROM at a particular point in time and vice versa. I only use full backups and full restores because something obscure will inevitably depend on data created under the same ROM environment.

I'd get used to setting things up from scratch when switching amongst ROMs to avoid those quirks.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] lafester:
That's a pretty good deal. Hope he takes you up on it.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bmckenna:
So, to clarify - with regards to restoring, I had factory wiped/deleted storage on my device when unlocking the bootloader per normal process, installed Lineage fresh, used it for a week or two, decided to try another ROM, booted into TWRP, backed up Lineage install, wiped data/cache/system, installed new ROM, wouldn't boot, wiped data/cache/system, installed Lineage, booted for first time, went back into TWRP, restored from backup (which wiped data/system), wiped cache for good measure, rebooted and here I am with my restored environment. Should be no mixing/matching of data/system. Issues existed before restoring data/system.

Not sure add-on wise what you're referring to. I actually kept my device unrooted because BlackBerry Work (needed for work e-mail) won't work if the device is rooted. Been a pretty stock-Lineage experience thus far.

The two things I had debated changing, but haven't:

Lines in configs/audio/mixer_paths_0.xml to correct sounds being played on both speaker and headset while connected to any device. This was, say, ringtone/notification tones/volume adjustments being played while my bluetooth headset was connected. I think the whole point of having headphones connected to a device is to ensure nobody else has to deal with your device making any noise :). Haven't tested to see if this will work but saw it in another thread - "Troubleshooting Bluetooth Issues on LineageOS 14 devices" by Harinus, on these forums. https://xdaforums.com/lineage/general/kb-article-troubleshooting-bluetooth-t3646969

Issue 2 was BeatsX (my daily usage bluetooth earbuds) not being able to use phone profile. Same symptoms as described here (this was with Airpods) - https://www.reddit.com/r/LineageOS/comments/7l99zs/apple_airpods_no_phone_issue/

Phone profile was checked in the cog wheel next to the headset settings, but bluetooth would not work for phone calls or Hangouts calls. Someone had suggested taking a working ROM's bluetooth stack and installing it over Lineage's but I haven't done anything in that vein yet.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Masterjuggler:
Could you please share how you set up tasker in order to fix this? I'm assuming you have it cycle the speakerphone as soon as a call starts, but I want to check because I haven't gotten it to work for me.

I'm still figuring out what every function in tasker does, so a simple list of the settings you applied for this task would be appreciated.

Thanks!

Hi,

I've an issue that i really can't solve.

Everything worked perfectly but tonight i've lost a part of my mobile data : i have full LTE bar but with a small cross at bottom (in notification bar). I can go on Facebook, What'sApp... but i can't use google apps (Chrome, Play Store...)

I performed a factory reset, clean install LineageOS, but issue is still here.

On Reddit, some users have reported this bug few months ago, but no solutions : https://www.reddit.com/r/LineageOS/comments/5wi9pd/cellular_network_issues/?st=jcqpvgjk&sh=4deb7584

Installed the 1-22-18 nightly of Los 14.1 on the 22nd, and so far it seems great! I'm a long time user of CM and now of LOS so it's all relatively familiar territory. Just the same it's nice to go from stock b32 (with which I had encountered a few bugs) to a clean near AOSP experience. It really livens the phone up too! Thank you guys for doing this for us, the community definitely appreciates it.

Is this ROM worth it?

I've used LineageOS on my Moto Z and loved it but because of the bugs it was a bit of a mixed bag in the end. The official Oreo launch is on the horizon and I'm a bit tired to spend my time flashing my phone every other weekend.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] eaponte23:
Backup your current ROM and take LOS for a spin. Give it a week. Let things settle in. Go with Magisk for root and add Atmos. Pray to the gods you don't have the call bug where you have to turn on/off speakerphone.

If you do, try Dark ROM(my daily driver, no bugs for my Axon7).

I haven't gone back to stock since I f'ed things up when I was a flashaholic a year ago.

did you succeed to make the "DEMO" mode working under the Dolby Atmos App ? (on my side it crashed systematically)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] soren25:
Yes, look up how to increase the number of volume steps. The default is 15, so 25 or 30 will probably be good. If you already have Magisk, there's a module you can install. If not, there's a build.prop edit that will work.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] eaponte23:
No ? Demo doesn't work
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] rackstar41:
I already try build.prop tweak, but it's not working (or I don't know which line to edit). What's the name of the magisk's module you're talking about?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] soren25:
It's called "Volume Step Increase." It's in the repo, so you can install it through the "downloads" section of the app.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] _phk_:
you need to add this entry into build.prop:

ro.config.vc_call_vol_steps=30

However I still have problems with voice quality. The other side has an echo and hears itself.

How do you root
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jawz101:
If you already have LineageOS installed on the download.lineageos.org page way down on the bottom left the last entry named "extras" has a link for the super user package.

https://download.lineageos.org/extras

You'd install this zip via recovery

For this phone it's this one

https://mirrorbits.lineageos.org/su/addonsu-14.1-arm64-signed.zip

Then, once it's installed, go into settings/ about phone/ click on build number a bunch of times until it says developer options are enabled.

Then go into settings/developer options

About 13 items down it gives the option to enable root for apps,adb, or both. I just choose apps unless you actually need adb to have root.

They purposely made root a separate install to keep LineageOS secure by default. You could also use Magisk or Supersu but supersu is closed-source and Chinese. Magisk is open source but it's another layer and doesn't feel as reliable as the LineageOS package.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] rackstar41:
I try the build.prop tweak and "Volume Step Increased", but it's only work for media (music in game or app) and In-call, but not for ringtone and notification.

I continue my investigation!

Hey [MENTION=4911249]Unjustified Dev[/MENTION] do u think that ZTE would help u to port Project Treble unofficially in the future like it was done on Xiaomi last days ago? Do we have any empty partition which could be used for vendor?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] OrdenKrieger:
No, unfortunately not. They use a partition that was normally used by Xiaomi for storing "MIUI regional customizations". We don't have something like that on the Axon 7.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] BlackAfghan:
That doesn't mean that Treble would be impossible. Treble is useful just for the sake of replacing outdated vendor blobs form Qualcomm. There isn't a month there no security flaws are fixed in propitiatory binary files! And ZTE isn't exactly updating them regularly..

And even if there is no dedicated /vendor partition available, doesn't mean there can't be one created from unused space. LineageOS uses way less space than the stock ROM. Although that could make it nessesary to revert that, in case somebody wants to go back to stock. But that wouldn't be a problem long-term since ZTE will stop updating it sooner or later anyways..
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] nupi:
Maybe I am missing something but since the stuff on /vendor is device specific, it would seem to me that the proprietary blob situation is not really addressed by treble
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] icenight89:
What you're speaking about is all possible, theoretically. But repartitioning a phone isn't a simple as choosing options while installing Windows. And there's the matter of pulling ALL the required vendor/proprietary blobs and sourcing them to the partition correctly. So its not finger snap simple

Treble project is amazing. It addresses the fragmentation and delayed updates issue in one fell swoop, updates not dependent on manufacturers because they are the only ones with the drivers.

And to be quite honest, the proprietary "situation" isn't a situation anymore. It was only one to begin with as devs used to take blobs from similar hardware phones and hack it together when one was no longer supported, to get a new android is version booting and semi working with hardware. Now that doesn't matter.
