I have a rooted Samsung Galaxy A5 2016 with v4a. Spotify works when applying the attach audio effects in v4a settings, however youtube won't. I installed this module with every single combination in the installer but youtube still doesn't work with v4a. Can something be done ?

I have DDP, JDP, AML and ACP installed.

I've noticed over the pass few days that I'm getting a crackling sound from some games and notifications.

I unistalled the patch and everything is back to normal.

Is this a bug?

@Zackptg5 ACP v2.0 is still not loaded at all with AML 4.0. Files are taken by AML and .aml.sh is failed to patch it again.

Without AML, its failed to patch audio policy, but usb audio policy only..

Can you flash acp, save the log in magisk manager, then attach that and the acp folder (zip it up) in /data/adb/modules_update? (Do this all before rebooting)

Still didn't patch audio policy, but only usb policy
btw v1.7.3 is patching audio policy correctly, even aml failed

It patched audio policy fine, looked over your results from 2.0 again and patched fine there too (I was looking for remove stuff instead of patch stuff lol)
So the remove logic is the old school deep_buffer remover and stuff where the entries are removed from the routes at the bottom of the xml file. With the patch logic (recommended because less buggy stuff happens with it vs removed), certain lines are changed. In the case of an xml (like yours):
  • deep_buffer and low_latency mixPort flags are replaced with "AUDIO_OUTPUT_FLAG_NONE"
  • raw mixPort flags are replaced with "AUDIO_OUTPUT_FLAG_FAST"

Checkout the common/install.sh file in v2.1 update I just pushed. It's much more readable/simple then the v1.x releases because I switched from unity to mmtex templates to make it magisk only - patches are simple removes rather than backups/substitutions

Can you try redownloading and installing? The aml log is giving an error for a line I removed in the latest update. Github can lag behind by a few minutes due to catching

    This fixes music and streaming apps (Spotify, Pandora, etc) that aren't processing audio effects for various equalizer applications through the modification of audio policy.

    Starting with v1.6 USB_policy patcher (upp) and Notification_helper remover (nhr) have been combined with acp. upp is to be used for usb dacs for v4a/jdsp. nhr is to remove notification_helper from audio_effects or delete the libvolumelistener.so binary. this prevents the "ducking" of v4a when you recive a notification and that notification comes in while playing music and v4a unprocesses and the processes again after the notification causing the volume to be extra loud. this stops that.

    The vol key options are as follows :
    - " Do you want to skip audio_policy patching? (Original acp before became 3in1 module)" This is asking if you want to skip what acp was before the combining of modules. if you are installing acp for spotify to process with v4a or jdsp then you'll want to select no here.
    - " Would you like to skip notification_helper remover?" If you dont mind the "ducking" v4a does or if it doesnt happen or your device then you'll want to select yes here.
    - " Would you like to skip usb policy patching for usb dacs?" If you dont use a USB extrenal DAC and v4a then you can select yes here.
    - " - Use lib workaround? -" If you arent having issues then you can select no here. Pixel 2's, 3's, and essential phones will have this selected as yes automatically.

    In light of recent discoveries, udbr has been redone and rereleased as Audio Compatibility Patch. The reasoning behind this is:
    • raw also needs removed in addition to deep_buffer on some devices
    • Instead of commenting out or removing deep_buffer and raw, we can instead change the flags to 'AUDIO_OUTPUT_FLAG_FAST'
    These together make this a more complete solution and should fix lots of compatibility issues some users were having.

    - Reworked the way deep_buffer removals function when a user uninstalls
    - Unity/AML v2.0: Massive installer and script overhaul
    - Unity v2.0: Added autouninstall (if mod is already installed and you flash same version zip again, it'll uninstall), thus removing the need for an uninstall zip

    - Unity v2.0: Added file/folder backup/restore of normally wiped files
    - Unity v2.0: Added Osm0sis @ xda-developers uninstaller idea (just add "uninstall" to zip name and it'll function as uninstaller)

    - Unity v2.0: Added system_root support for Pixel devices

    - Unity v2.0: Add Unity system props
    - Unity v2.0: Added vendor fix for Nexus devices
    - Unty/AML v2.0: AML functionality and uses overhauled

    - Unity/AML v2.0: Moved scripts from Magisk .core to the individual module folder due to .core limitations

    - Unity v2.0: Reworked addon.d system install scripts
    - Unity/AML v2.0: Removed AML cache workaround by reworking AML changes via magisk_merge
    - Unity/AML v2.0: Reworked AML vendor audio_effects to not be overwritten by system audio_effects by commenting out conflicting lines
