Missing `libpulse.so.0` causes test failure when using FMOD

**Bug description**

When testing an app that uses FMOD using [game-ci/unity-test-runner](https://github.com/game-ci/unity-test-runner), the library `libpulse.so.0` is reported as missing, causing the test to fail.

```
[FMOD] FMOD_OS_Library_Load : dlopen failed to open 'libpulse.so.0', dlerror = libpulse.so.0: cannot open shared object file: No such file or directory
```

**Expected behavior**

The `libpulse.so.0` library should be available on Ubuntu images, since it's needed by FMOD.
