Is that for sure?
AUDIO_OUTPUT_FLAG_DEEP_BUFFER is used in my android_device_sony_kitakami-common/audio/audio_policy_configuration.xml in this sector:
                <mixPort name="deep_buffer" role="source"
                    <profile name="" format="AUDIO_FORMAT_PCM_16_BIT"
                             samplingRates="44100,48000" channelMasks="AUDIO_CHANNEL_OUT_STEREO"/>
My patch changes the buffer size of the "primary output", The primary output is used to play notification sounds phone ringing etc. Audio crackling appears exactly in this situations e.g. when the phone wakes up and plays a notification sound.
The mixport "deep buffer" (that's the snippet you've pasted) is used in completely different situations i.e. when playing music through a music app.

Be aware, that my change increases the audio latency of the primary output.

Hi Berni Thanks for your work,

I've spent today trying to change the rom on my phone i've been able to unlock the bootloader but im getting stuck installing twrp i have tried both your version and the TWRP 3.2.1 (pick the version from 2018-02-23!!!) but im getting stuck and no searches have helped so far they all lead to issues for other phones none for the z5c

In the command prompt im getting this error:

fastboot flash recovery recovery.img
Warning: skip copying recovery image avb footer (recovery partition size: 0, recovery image size: 12296192).
Sending 'recovery' (12008 KB) OKAY [ 0.281s]
Writing 'recovery' FAILED (remote: 'Command not allowed')
fastboot: error: Command failed

Its been a while since ive been installing custom roms the last was a few years back so i sort of know how to do most things when i had a z3c im sure i had a custom rom or two on that :)

Hoping someone can point out where im going wrong and i can get this on my phone

It seems that your device has not unlocked the bootloader.

Please try to repair the device using the recommended tool from Sony itself (XperiaCompanion?) and after that you should use the service menu *#*#7378423#*#* to evaluate if you really can unlock the device.

If yes, you should flash and install the latest stock ROM 32.4.A.1.54 using the FlashTool.

After that is successful, you can try to flash a custom ROM.

Peformance was good enough and video recording lags on 1080 back camera and 480-1080 front cam, but lowering it to 720p back cam and CIF quality on front fixed the issue and it save to the sd card. Overall good work for the z5 compact Berni!

    I had to replace this version with a newer one; see 1st post.

    The previous version was missing a few less critical patches.

    Please update as soon as possible.

    I'm sorry for any inconvenience.

    Hi all:

    Here is a LineageOS 19.1 ROM for Z5 compact (suzuran).

    New: ROM with microG apk's included in priv-app:
    Download 2023-03-26

    Please pay attention: microG can't coexist with GApps! So decide whether to install microG OR GApps!

    If you want to remove microG, enter these commands line by line in a terminal:
    adb root
    adb shell
    mount -o remount,rw /
    rm /system/priv-app/DroidGuard/DroidGuard.apk
    rm /system/priv-app/FakeStore/FakeStore.apk
    rm /system/priv-app/GmsCore/GmsCore.apk
    rm /system/priv-app/GsfProxy/GsfProxy.apk


    Or flash this microG-remover.

    This is a 7z archive with the zip'ed ROM and the md5 file in it. Please unpack this archive, copy the included two files somewhere to your device, reboot into TWRP and flash this zip file. Enable md5sum checking. The zip file itself is not signed, so you have to disable zip verification.

    • Using Sony blob's from stock version 32.4.A.1.54

    Important informations:
    • You should be familiar with general installation of custom ROMs.
    • Required for installation: TWRP 3.2.1 (pick the version from 2018-02-23!!!)
      OR use my self built TWRP-version 3.7.0!
    • This ROM needs a clean install, old /data may cause problems!
    • This ROM is NOT pre-rooted. For rooting you can use Magisk.
    • It is highly recommended that your device is running (or HAS RUN in the past!) the latest stock ROM from Sony (32.4.A.1.54) before flashing this ROM.
      Otherwise the baseband files may not match.
    • Audio
    • Bluetooth
    • New: Camera fully working!
    • Enforced SELinux support
    • Fingerprint (sometimes crashes)
    • FM-Radio (maybe it needs a few restarts before it's working)
    • GApps

    • VoLTE
    Maybe some more things are not working. Please tell me...

    Use this ROM at your own risk! It comes without any warranty! I'm not responsible for any damage! If you don't agree with that, don't try to flash this ROM in any way.


    • Added Aurora-Store, F-Droid and UnifiedNLP! If you don't want this, simply de-install it.
    • I've set maximum speaker volume to a higher value.
    • I've increased microphone gain.
    • I've changed the microfone gain to avoid echo in phone calls.


    • If you're running into an error, please search in this thread if this error is already posted, before you post it again!
      If not, I need a LOG to see what went wrong. Without a LOG I can't help you!
      A LOG can be fetched by connecting the device with an USB cable to your PC and then by typing these commands line by line:
      adb root
      adb shell logcat -b all -d > logcat
      Send my this LOG file via PM.
    • If you think this could be a SELinux related issue, please try to set the device to permissive mode first.
      If the issue is gone, I need the policy file too (plus LOG). Fetch it by typing this line in a terminal:
      adb pull /sys/fs/selinux/policy
    • If you stuck in a bootloop you can fetch a LOG with this trick:
      • Press the power button and the volume up button together until the device shuts down.
      • HOLD the power button.
      • Release the volume up button and press the volume down button immediately after releasing the volmue up button.
      • The device should start into TWRP recovery.
      • Tap on "Advanced", then on "Terminal" and enter these commands line by line:
        cd sys/fs/pstore
        cp * /sdcard
      • Send me the copied file(s), if any, via PM.

    One last request:

    Please, do not ask about problems for which my ROM is not responsible.
    From now on I will only react to problems that I can reproduce and that are caused by my ROM.

    I'm sorry for that, but I'm developing this ROM in my spare time and I still have a normal life.
    Dear Bernie-0815,

    Your ROM 19.1 works like a charm. Had it installed two weeks ago and tried all kinds of stuff; nothing failed so far. I just wanted to give you a very huge Thank You! for your efforts and your great work.

    I used the old official Lineage 14.1 until now because I was hesitant to try an 'unofficial' version. But your ROM has breathed new life into this smartphone which I attempt to keep for a number of reasons (small size, headphone jack, not interested in fancy new hardware etc.).

    So, I just wanted to reach out and thank you for making it possible to use older, yet absolutely functional smartphones longer. I recommended your ROM to a friend also using a Z5 compact (still with the stock Sony ROM) and think she'll soon go for it as well.

    Keep up the good work, and be assured that there are people out there still using the Z5 Compact on a daily base and in productive mode!
