Fixing System Audio Problems with Android Emulator on Ubuntu 18.04

Ubuntu 4

In this article, we will be discussing how to fix system audio problems with the Android Emulator on Ubuntu 18.04. Users may experience distorted and metallic system audio while running Google’s Android emulator on Ubuntu 18.04 with the latest version of Android Studio.

Quick Answer

To fix system audio problems with the Android Emulator on Ubuntu 18.04, you can try updating PulseAudio, ALSA, and Android Studio, adjusting audio settings in pavucontrol or the system settings audio panel, or using the -noaudio flag to start the emulator without audio. If these solutions don’t work, consider reporting the issue to the Android Studio or Ubuntu community for further assistance.

Understanding the Issue

The issue occurs regardless of whether speakers or headphones are used. One common workaround is to start the emulator with the -noaudio flag from the terminal. This resolves the sound issues but is not an ideal solution as it completely turns off the audio. The problem may be related to a bug in PulseAudio or ALSA integration, which are the sound servers used by Ubuntu.

Possible Solutions

Updating PulseAudio, ALSA, and Android Studio

Firstly, it’s always a good idea to ensure all your software is up to date. This includes your sound servers (PulseAudio and ALSA) and Android Studio. You can update your software by running the following commands in the terminal:

sudo apt-get update
sudo apt-get upgrade

The apt-get update command is used to re-synchronize the package index files from their sources. The apt-get upgrade command is used to install the newest versions of all packages currently installed on the system.

Adjusting Audio Settings

Another solution is to try adjusting audio settings in pavucontrol or the system settings audio panel. This could involve switching between digital and analog output. To install pavucontrol, use the following command:

sudo apt-get install pavucontrol

Once installed, you can open pavucontrol and adjust the audio settings as needed.

Using the -noaudio Flag

As a workaround, you can start the emulator with the -noaudio flag from the terminal. This command will start the emulator without audio, which can resolve the sound issues. The command is as follows:

emulator -noaudio -avd my_avd

In this command, -noaudio is the flag that tells the emulator to start without audio. -avd my_avd specifies the name of the Android Virtual Device (AVD) you want to start.

Reporting the Issue

If none of the above solutions work, consider reporting the issue to the Android Studio or Ubuntu community. The communities are always willing to assist and you may find others who have experienced similar problems and have found fixes or workarounds.

Conclusion

While the above solutions may not completely resolve the issue, they provide a starting point for troubleshooting audio problems with the Android Emulator on Ubuntu 18.04. Always ensure your software is up to date, and don’t hesitate to reach out to the community for help. It’s also worth noting that these issues may be resolved in future updates to Android Studio or Ubuntu.
