Can not install APK modified for Dolby Audio

I'm using a Moto G6. With the latest update of Android 9, they removed the possibility of using the built-in Dolby Audio equalizer for a stupid reason. I found this article reddit which allowed to modify the APK for this to work. I followed all the steps. I decided to try the steps of the 20 band equalizer and I made a backup of the previous work before starting. However, when I finally managed to install adb DaxUI2.apk, it did not work. I had this error:

adb: failed to install DaxUI2.apk: Failure (INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.dolby.dax2appUI signatures do not match previously installed version; ignoring!)

It was sad, but not serious, right? Because I've already had a backup. I renamed the DaxUI2 folder to DaxUI2broken, renamed my backup to DaxUI2 and tried it again, with only the first part (without the appendix). Once I did that, however, I had exactly the same mistake.

I would like to be able to solve this problem, so if someone knows how, tell me please! Thank you in advance.

(added later) Initially, I had posted this on superuser, apparently it was off topic (sorry, I have not used it for a while), so this is a copy pasted. In addition, I would like to add that I do not know anything about it, but that the guide seemed to work for other people. Thanks in advance!

How to import an MP4 audio book into iTunes to play it on an iPhone?

How to import several MP4 files constituting an audiobook in iTunes in order to be able to synchronize it with my iPhone?

I selected Audio Books and I tried to drag and drop the folder and files into the window, but that did not do anything. I tried to select File> Import Folder and Import File, but nothing has been done yet.

All system audio transmitted during calls

So I have a Huawei Y9 (2018) running Android 9 with EMUI 9.1. Whenever I'm in communication (I only found it for the moment with Messenger), all the sound of my notifications and my media (if any) is also transmitted during the course of the day. 39; call and the other person complains of having to hear them. I do not know what's really going on. Help?

No DispalyPort Option in the Audio Output Device Menu, Nvidia Drivers

I can not display my monitor connected to DisplayPort (AW2518HF, connected external speakers) in this drop-down menu:
Settings> Sound> Output> Output Device.

I have opened the Nvidia X server settings and I can assure you that DP Audio is enabled. In addition, I started Windows 7 and was able to select it and play a perfect sound.

I'm using a GTX 750 (EVGA; they've added a DP port in their version) with the 418 driver installed from Software & Updates on Ubuntu 19.04.

unit – How to make sure that an audio source transmits 2 specific scenes?

I am working on an audio source for my main menu and I am helping the scenes I want to wear on both scenes but be destroyed on all the other scenes. I encounter many problems, for example if it does not destroy on other scenes or if I come back to the previous scene, it generates 2 audio sources, etc. Here is the script:

public class DestroyAudio : MonoBehaviour
    void Awake()
        SceneManager.sceneLoaded += OnSceneLoaded;

    void OnSceneLoaded(UnityEngine.SceneManagement.Scene scene, UnityEngine.SceneManagement.LoadSceneMode mode)
        if (( == "Help") || ( == "Main Menu"))

Measurement – Is there any software, regardless of the operating system, able to measure the load impedance of an audio output?

I do not worry if it is inaccurate or could cause damage to the socket. I just want to know if this has already been done. There is online information on the use of an input as an oscilloscope, but I am trying to measure the load impedance of an output. Does anyone know if there is software that allows you to perform arbitrary measurements in ohmmeter on computer audio jacks?

8.0 oreo – The Android audio output cuts and returns to the BT headset randomly.

This happens more often when I move the phone, but I can not get sound to stay on my headphones.

It does not show the drop-down list of the audio output before the switchover, but when it does, it indicates that the sound is transmitted to the phone.

However, I hear no sound from the phone and when I increase the volume, the headphones symbol is displayed.

For this to happen, the BT headset that I used does not have any importance.

Cloud storage for streaming audio files

I work on a WordPress site for a client who has about 200 audio files or songs and who wishes to include them on the site as publications with the ability to read songs using a media player on the site.

Now, I prefer not to store the files on the local site. So I wonder if people have any suggestions on free storage of audio files to be streamed from a wordpress site?

Are you also interested in suggestions from media players that can pay for remote audio files?

Thank you

ffmpeg – Setting (rather than resampling) audio in a video file

I have recorded a live stream with OBS and my audio sampling frequency has been set to 44.1 KHz. Unfortunately, OBS has interpreted the audio input of my device as being 48 KHz. So there are a lot of problems and the audio is set at about 9% higher (which was the case during the stream itself, although no viewers realized that this was happening at the time.).

Is there a way to use FFMpeg or similar to change the audio stream sample rate (and probably remux), without trying to resample the audio?
