The Android Studio emulator doesnt sound. Ubuntu 19.10 distribution

I have an MSI P65 with Ubuntu 19.10 distro. My emulator in Adroid Studio is not working properly. It doesnt sound. The event log of Android Studio show these warnings/erros:

• 18:41 Emulator: Fontconfig error: "/home/fabrizio/.config/fontconfig/fonts.conf", line 10: junk after document element

• 18:41 Emulator: pulseaudio: pa_context_connect() failed

• 18:41 Emulator: pulseaudio: Reason: Connection refused

• 18:41 Emulator: pulseaudio: Failed to initialize PA contextaudio: Could not init `pa' audio driver

And if i use the command 'pulseaudio' in terminal i get these errors:

• E: [pulseaudio] pid.c: Daemon already running.
• E: [pulseaudio] main.c: pa_pid_file_create() failed.

Already tried to delete the files into .config/pulse but it didnt work. As u can wonder: work with an emulator in this condition is insane.

Please Help.
