Just updated.

Can confirm charging issues, but with different symptoms to previous issues:

Charges to 100%, but percentages jump up and down several percent at a time, eg from 79 to 90%, or from 100 to 82%. Also, after 100% seems to discharge even though led and lightning symbol are on. (Percentages keep decreasing, and script at bottom of lockscreen says 'charged' instead of 'charging'.) And if powered off in this state, led remains on after powered down despite charging cable removed.

(Should I try different boot.img?)

Hope it helps, PW.

I turned off my phone and disconnect usb cable and after few seconds led turned off too. when I powered on my phone , it was 100%. everything was normal.

Yes, mine is L02, and dirty flashed.

Charging problems persist. Sometimes need to remove and replace battery to correct behaviour in powered down state. Powered on, overnight, level often 50-60% with charger attached (if hotspot on), and lockscreen info stuck on 'charged'. Suspect boot.img may not be fully compatible with L02. PW.

[Android Q&A, Help & Troubleshooting] pndwal:
See post #5730

Previously, I had AudioFX working with speaker, but not with headset (headphones).

Fixed this problem (and still working with latest ROM) by installing AML (Audio Modification Library: Framework to allow seamless integration of multiple audio mods -This fixed audio anomalies, and now AudioFX works properly [incl. headset]!), ViPER4Android FX, or any other audio mod utilising AML.

I use Magisk for SU (root), so simply installed ViPER4Android FX for Magisk v14+ module from Magisk Downloads (in addition to Busybox for Android NDK).

Now can use ViPER4AndroidFX and/or AudioFX. All works well, and Viper is far more versatile than AudioFX, with myriad effects / controls, incl. extra gain, etc. (Invokes Googles warning 'this app can damage your device' so use with care especially at high volumes on speaker mode, etc.)

Guess you could try flashing these, or alternative files, from TWRP if using SuperSU, but they're designed as Magisk modules, and they install simply from Magisk Manager and work well.

Hope it helps, PW.
[Android Q&A, Help & Troubleshooting] pndwal:
Thanks for that. I'll try clean install when I have time to backup, restore etc, and report. Tried various chargers (incl. Aukey with Qualcomm fastcharge) and powerbanks already. All similar. PW.

See post 5779 re. In Call problems. PW.

(See 5764 also)

I tried to add audio_platform_info.xml to /system/etc to play will it's entries, but I haven't been able to make it stick on reboot (it's deleted.)

Please let me know if you know how to make system files (and file changes) stick in lineage. (I'd like to try, however audio_platform_info.xml may have no effect without changes to boot.img also.) PW.
[Android Q&A, Help & Troubleshooting] Saint_13:
I used solid Explorer and lineage Built-in root, duplicated audio_policy_configuration.xml and then renamed that to audio_platform_info.xml

replaced codes with this from google

after restart audio_platform_info.xml was there and not deleted, but my phone's back speaker didn't work. and nothing happened to in call volume adjustment.

then replaced codes with your codes after restart audio_platform_info.xml was there too, phone's back speaker worked well but nothing happened to in call volume adjustment.

audio_platform_info.xml was there even after several restarts.
[Android Q&A, Help & Troubleshooting] pndwal:
Well done!

The codes you used initially were from Nexus Marlin. The three sets of codes I provided were also just samples from other devices, so clearly getting correct entries / values for Y550 is going to be a challenge (especially as no stock ROM includes audio_platform_info.xml).

Also, as I mentioned, audio_platform_info.xml may have no effect on in-call vol control without changes to boot.img also. Phones fixed by adding audio_platform_info.xml at least sometimes needed new / configured boot.img. (see my post 5760).

So seems it will take much googling / experimentation to get this right for y550, but my research strongly suggests we need to do this as past efforts with 'fluence' settings etc have had only limited success as they are treating the symptoms, not the underlying problem, which seems to be Android's or Lineage's new requirement for audio_platform_info.xml file with correct acdb id values (missing in all Y550 ROMs to date) along with a compatible boot.img. The lack of these appears to be the cause of both Echo for Other Party and No In Call Volume Control problems.

I'll have a try with your method for adding XML file when I can and appreciate your efforts / input. My hope is that someone more knowledgeable than me may also know how to obtain correct values for y550, as well as what needs to be changed (if anything) in boot.img. PW

[Android Q&A, Help & Troubleshooting] Garanews:
Just a question, I formated the sd to use as internal but system still saying "few space left". how to do?
[Android Q&A, Help & Troubleshooting] pndwal:
See my post #5784 for info on Adoptive Storage use.

Sounds like you may not yet have performed 'migrate data to SD'. Needs to be done after formatting as Adoptive, otherwise you will still have only phone memory available for your data.

Some points that may help:

Post #5708

Go to settings, storage, SD card, 3 dot menu at top - and select Migrate data to move data from internal to SD.

Then go to Internal storage, Apps, and individually move any apps that have CHANGE button that haven't been moved automatically. Newly installed apps will be installed automatically on SD if developer supports SD installation.

If Devs haven't added 'move app to SD' support for some apps (and you want to move more), you can still move them. Go to Developer Options, select 'Force allow apps on external' in (Makes any app eligible to be written to external storage, regardless of manifest values).

In a standard file explorer (and with usb mtp computer connection) you will now see only your SD card, which is now your phone (user) memory (ie user data partition), and this has changed to the capacity of your SD card. It doesn't show up before migrating data, even though formatted as internal, as user data partition needs to be swapped to it from internal and the migrate data process does this. That's why there is no longer any internal phone memory showing. (It's now freed up for basically system data, system apps, and unmoved user apps.)

Post #5727

Dont forget, for good results you need a fast SD card. I use 80MB/s SanDisk Ultra 64GB SDXC, but faster would be better.

Hope it helps. PW.

[Android Q&A, Help & Troubleshooting] Garanews:
After format if I try "migrate data", after ~20% I receive "no enough space" error. Of course SD has 99% free space, but when press migrate data it seems that the internal memory (where only500mb are free) is going to fill, then receive the error and returns to 500mb free, like that "migrate data" is trying to move sd data in internal memory instead the opposite...

And under dev options I don't have the "Force allow apps on external' feature.
[Android Q&A, Help & Troubleshooting] pndwal:
I had similar problems in MM, but thought it was fixed in N. I've had no problems since.

You could try different SD, or reformat on computer as ext4 before formatting as internal on phone. (Also, some 'fake' SD cards are sold, eg 32GB card masquerading as 64GB).

Some found app cache to be the culprit. Try wiping in twrp, or go to Settings, Storage, Internal shared storage (or SD card), Cached data, and click OK to clear cached data for all apps.

Also, what sizes are reported in Storage settings for SD card (Settings, Storage)? PW.

[Android Q&A, Help & Troubleshooting] pndwal:
I've just been revisiting what works to fix AudioFX, and although initially the fix was simple, its become a little more complex now.

I hadn't noticed it had stopped working again with magisk module updates as I've been using ViPER4Android FX module (V2.5 by Ahrion, zackptg5), which I prefer for reasons I explained.

Got it going again by downgrading AML manually in magisk to v 1.4 (Audio_Modification_Library-v1.4.zip) and disabling ViPER4Android FX as well as any other modules that now incorporate AML by Ahrion, eg Universal deep_buffer Remover, which now utilises/ installs AMLV2.5.

As I mentioned, originally AudioFX was fixed simply by installing AML which came as a stand alone module in the magisk repository, or by installing ViPER4Android FX, or any other audio mod utilising AML. (See post #5834). Now however, AML is no longer provided as stand alone module (ie no longer shows up in magisk downloads (repo), having become a utility for Ahrion or other developers to include in their audio mods, (see https://xdaforums.com/android/software/module-audio-modification-library-t3579612) and the updated AML versions used in these now break whatever code AudioFX needed in v 1.4. As a result, it's either AudioFX or ViPER4Android FX etc, but both will no longer work together.

I use Magisk for SU (root), so I simply installed Magisk modules. As I said, I guess you could try flashing these from TWRP if using SuperSU, but I really don't know how this would go.

I'd recommend Viper or other audio mods which include Ahrions AML for Magisk over AudioFX anyway. Here's the current list: Ainur Audio Sound Mods - (These include Sauron, various ports, and JamesDSPManager.), JamesDSPManager, AM3D Zirene Sound, Collective Dolby Atmos Ports, Viper4AndroidFX.

Hope it helps, PW.

---------- Post added at 01:27 PM ---------- Previous post was at 01:19 PM ----------

Yes, if AML v 1.4 is installed (as explained above), AudioFX works properly with headphones, speaker, Bluetooth.

Later AML versions break this fix however.

[MENTION=7550078]pndwal[/MENTION] : so without this (AML) audio fx is not working properly. .. have to buy new heaphone to test cos i lost mine...:o
[Android Q&A, Help & Troubleshooting] pndwal:
Correct.

As [MENTION=4165581]blairfancy[/MENTION] said, app loads and seems to respond, but has no effect on sound (other than with speaker).

Early AML (v 1.4) fixes this completely, but AML is only meant to allow compatible audio mods to operate without conflict as the op explains. AudioFX is not on compatible list, so seems a fluke that an early version of AML fixes it, especially as recent updates don't (updating breaks fix).

AML compatible mods like Viper4AndroidFX continue to work well with magisk module updates, and are in my opinion, better alternatives to AudioFX. PW.
