Just so you guys know, all zips from 0.7 to 0.722 have borked variables and should not be flashed.

0.723 has the fix (which ends up fixing many others) and is the only zip to flash, unless a version before 0.7 (when new variables were introduced) works great for you.

I have removed all attachments I could find and if any others are found attached or shared elsewhere, it would be a very kind gesture to point out the issue so that it can be removed or replaced with version 0.723 or higher.

Yes, I omitted "PIE" from the zip's name so that it would no longer be confused as being limited to Android 9 since more than enough Android 10 testers have confirmed the port to be functioning - even with my many, many mistakes lol.
Lol i still using 0.64 :)) it work well but some of my people gor Bluetooth issues that won't turn on some how...and yeah they are on OOS 10 :(( but yeah good work!

I know you guys are tired of me apologising, so I'm not lol.

I just now spotted a vendor variable error breaking or misdirecting several functions. I don't know how many versions this has been included, but certainly a few, at least.

The corrected version is attached below.

Flashed this zip on a10. System UI isn't responding error popping up like in the case of Sony port . SS , volume buttons borked etc. Strangely effects seem to be working .

I've tried installing this on my OP7Pro running OOS 10.3.0 but it keeps crashing. Please let me know if I need to provide more information.

I have tried almost all version posted by OP including the latest v723 and in all version, system boots and port works fine but facing certain apps/UI freezing but surprisingly not in the one that you posted (v64) so I stick with v64 for now.

The "surround-boost-value" in the following coding, what's the range of the value? Is that in percentage?
Is a reboot required to make the changes go into effect?
<endpoint_type id="headphone">
<calibration-boost value="0"/>
<dialog-enhancer-enable value="true"/>
<dialog-enhancer-amount value="0"/>
<dialog-enhancer-ducking value="2"/>
<surround-decoder-enable value="true"/>
<surround-boost value="96"/>
<volmax-boost value="96"/>
<volume-leveler-enable value="false"/>
<volume-leveler-amount value="0"/>
<volume-leveler-in-target value="-320"/>
<volume-leveler-out-target value="-320"/>

    The troubleshooting guide for Release Candidates is in this post.

    updated 20200206

    "Listen to the Dolby Atmos™ Difference!"

    Dolby Atmos™
    Android Oreo


    • Dolby Atmos™ Digital Signal Processer with effects and Graphic User Interface ported from the latest ZTE™ Axon 7 Android Oreo firmware intended for all Android devices on Android Oreo.

    • Dolby Atmos™ sound effects applied to media audio output supporting various media players.

    • Flexible custom recovery installation archive supporting Magisk and SuperSU installations as well as existing audio mod installations - fully supporting Enforcing SELinux Mode:

      • Multiple installation scenarios available using the included arise_parameters.prop that is automatically copied to /sdcard if not already there. When edited by the user in this /sdcard location, arise_parameters.prop can:

        • Instruct an installation directly to /system if a Magisk user prefers a /system installation over the Magisk module installation.

        • Instruct a system-less module installation using /su if a SuperSU user with the system-less SuperSU installation prefers a module installation for a variety of reasons such as insufficient /system space to accommodate a /system installation or the convenience of a persistent installation unaffected by rom updates.

    • An independent build maintained by @[B]Zackptg5[/B] fully integrated with Unity:

      • Active accommodation of existing and future Magisk modules relevant to audio modification.

      • Flashing the installation archive over a current installation results with an uninstallation of the Dolby Atmos™ Magisk module.

      • @[B]Zackptg5[/B] explains the nuances a bit further here.

    • A minimum of SDK 26 (Android 8.0) is required for installation to begin, else Exit 1 will abort the recovery installation activity.

    • A root solution or a capable kernel is required in order to automate the execution of scripts during boot to allow the appropriate sepolicy rules necessary for Dolby Atmos™ functionality while in Enforcing SELinux mode.

    • Third party audio effects and DSP's such as ViPER4Android (<--
      link to @[B]docnok63[/B]'s solution :highfive:) may require some extra effort to allow processing due to Dolby Atmos' dependency on its output_session_processing music effect.

    • Performing a backup of the /system partition in recovery is encouraged for users receiving a /system installation:

      • TWRP > Backup > Check System > Edit name, if desired > Swipe to perform backup operation

    • Confirm device requirements are met and installation results are acceptable.

    • Confirm an escape route is available in the event of unsuccessful device boot or unsatisfactory experience.

    • Confirm successful download and location of downloaded archive(s).

    • Boot to recovery > Install > *.zip > Swipe to perform installation operation > Advanced > Copy Log > Reboot

    • Updating procedure is no different unless specified otherwise.

    Additional Information:

    • Unsuccessful device boot:

      • If experiencing a bootloop...

        ! ! DO NOT GIVE UP ! !

      • Wait until at least 60 seconds have passed, hold down the device's Power button until a reboot is initiated... and then give up if a successful boot fails to occur.

    • Escape routes for unsuccessful/unsatisfactory installations:

      • Magisk Module Installation:

        • If booted, navigate to /magisk using a capable file manager application and delete /dolbyatmos before rebooting the device. If experiencing an unsuccessful device boot, boot to recovery using the appropriate hardware button combination for the device, install the Magisk Recovery Management archive attached below, and follow the given instructions to delete the Magisk module (/magisk/dolbyatmos).

      • SuperSU /system installations:

        • Restore Backup in recovery if available: TWRP > Restore > appropriate backup folder > Check System > Swipe to perform Restore operation

        • Install the currently installed rom zip in recovery without any partition wipes or install a different rom zip according to the rom developer's installation instructions.

    • Reporting bugs/failures:

      • An acceptable report will include the /sdcard/recovery.log received after the installation session before booting from recovery even if the recovery session appeared to be free from any error. An acceptable report will include relevant information/details to equip me to efficiently address the report.

    • Auditing:

      • Assessing the installation is encouraged for all users and is especially helpful when the collected information is included in reports of less than perfect experiences.

      • Dumpsys:

        • The dumpsys utility in Android can be a very valuable troubleshooting tool, especially audio output processing related issues, when targeting the audioflinger service. Recommended terminal applications include Terminal Emulator for Android and Termux.

        • In Android Terminal:
          dumpsys media.audio_flinger
          su -c dumpsys media.audio_flinger

        • The output generated upon tapping the Enter key is the information of interest and can be copied from the Terminal and pasted with a report, if necessary.

        • This output includes the list of successfully configured audio sound effect libraries and any successfully created effect-chains from one or more of those libraries when combined with the successful installation of an appropriate apk, Dolby Atmos being one of many examples.

      • Logging:

        • The log utility in Android is another valuable tool for many various purposes, including troubleshooting. This utility is most convenient when used with a logging application such as Matlog in order to utilize features such as word filtering and syntax highlighting among others.

        • Using the logging application's search feature, the user can filter the displayed log output using words or characters relevant to this Dolby Atmos™ port such as: dolby, dax, dlb, dseffect and include that relevant log output with reports, if necessary.

    • Testing:

      • The possibility of my experience being different from others' experiences is always present!

      • Those meeting the installation requirements may certainly test against various aspects stated as facts within this OP such as incompatibility with other audio effects, requirement of Permissive SELinux Mode :highfive:, etc.

    • Vulnerabilities:

      • The installation, as with any device content, is not immune to impact from existing and future installations of custom content. This custom content may remove or modify necessary content, or introduce conflicting content preventing Dolby Atmos™ from functioning as intended by this mod's installation. Security measures can block these scenarios from occuring but will typically be implemented only after the discovery of such cases of "breaking" Dolby Atmos™ functionality, in which case, the relevant vulnerability will be omitted from this particular section.

      [B]Initial Release -[/B]

    Release Candidate 1:
    • 32-bit and 64-bit installations from a single zip.

    • Axon 9 Pro apk and effect library used in both 32-bit and 64-bit installations to provide the most consistent experience for all users.

    • This allows 32-bit users to avoid the 3dB GEQ boost limit as well as any license check by Lenovo.

    • Removed much of the verbose messaging during the installation.

    • Refinements and minor corrections to every single script.

    • Install ACDB 0.45 if not already installed.

    • Uninstall any existing Dolby Atmos™ installation and reboot.

    • Install RC1 in Magisk Manager or in custom recovery.

    • Save installation log before rebooting.

    • Apply your best effort to find a failure or force a failure of functionality by any reasonable means - deleting/overwriting something will not count, obviously.

    /system/bin/audioserver <-- Drive link

    • Purpose and Contribution:

      • Introduced with Android Nougat, audioserver appears as its own binary after years of being a component of /system/bin/mediaserver in all Android firmware.
      • Introduced with Android Nougat, vendor provided Dolby Atmos™ software audio solutions appear with a new media.dolby_memoryservice that is compiled into /system/bin/audioserver as well as a unique system library typically appearing as /system/vendor/lib/libdlbmemoryservice.so.
      • These new components are crucial to a functional Dolby Atmos software solution and there is currently no known way of achieving any amount of success without them.
      • While porting the very first Nougat Dolby Atmos system available, courtesy of ZTE™ Axon 7’s initial Nougat firmware image, I discovered this implementation and a functional port was finally available.
      • However, using a Nexus 6 at the time, I was able to evade nearly all bootloop scenarios with much of what would cause a bootloop scenario for others.
      • It took no time to determine that this new media.dolby_memoryservice component was going to be a challenge in achieving a viable Dolby Atmos Nougat port.
      • To begin, results were determined: Successful device boot or Unsuccessful device boot.
      • Stock firmware seemed to fare much better than custom firmware, even for just a single device.
      • A pattern began to emerge for me when focusing only on the audioserver binary: Stock firmware had an audioserver file size range (21.50KB-21.53KB) and Custom firmware had an audioserver file size range of its own (21.58KB-21.60KB).
      • Not a significant difference, unless you were looking for a difference.
      • This assessment presented an effective predictibility of an installation scenario's success and failure with nearly 100% accuracy (nearly only because every possible scenario is not documented).
      • This audioserver database is intended for those that have determined a single scenario as successful or as unsuccessful due to the native audioserver binary in their device’s rom being overwritten or symlinked over with the audioserver native to the ZTE™ Axon 7 Oreo firmware AND NOT A RESULT OF ANY OTHER FILE OR SCRIPT OPERATION!!
      • Simply, those with success have the easier path requiring nearly no effort other than uploading the native audioserver from their firmware along with the firmware build.prop to the WIN audioserver folder.
      • Those contributing to the FAIL audioserver folder with the native audioserver along with the firmware build.prop will only be able to do so after some personal testing to ensure the audioserver switching is the exclusive cause of an unsuccessful device boot after flashing the Dolby Atmos installation archive in recovery.
