   - Go back into **SYSTEM SETTINGS** -> **AUDIO OUTPUT** and test all available outputs, exiting to the **MAIN MENU** between each change.
   - If none of the **AUDIO OUTPUT** options worked, repeat steps 1-2 for a different **AUDIO PROFILE**. Your **AUDIO OUTPUT** options might change depending on the **AUDIO PROFILE** selected.
+If the appropriate options are not being listed in the menu, you could try using the generic name for the audio device by manually editing the configuration file. Open ''system/batocera.conf'' and modify (or add if not already present) the ''audio.device'' key to be:
+<code>
+audio.device=hdmi
+</code>
+where "hdmi" is the generic name for your audio device.

   - Remember the name/number of this working Audio output device (for example HDMI#0), exit Kodi and go to the Batocera **Main Menu** > **System Settings** > **Audio** and select the Audio output device, which has the same (or at least a similar) name to the one that works in Kodi. Then reboot and you should have working audio.
   - You can also diagnose some sound issues with the ''alsamixer'' sound mixer that is available when pressing ''[Ctrl]''+''[Alt]''+''[F4]'' (text-mode sound mixer). Make sure that all the outputs are enabled, and they have their volume up. You can return to Batocera with ''[Ctrl]''+''[Alt]''+''[F2]''.
+==== I still don't have any sound! ====
+In Batocera **v36** and higher, try activating the [[https://thesofproject.github.io/latest/introduction/index.html|newer SOF DSP handling]]:
+  - Open up an SCP session (or use Batocera's built-in file manager by pressing ''[F1]'' on the system list).
+  - Go to ''/etc/modprobe.d'' and open ''intel-dsp.conf'' in a Unix-compliant text editor (no, Windows' Notepad will not do). ''/etc'' is in the root directory, you may need to go up one level from the ''userdata'' folder.
+  - Edit the line which says ''options snd-intel-dspcfg dsp_driver=1'' to instead say ''options snd-intel-dspcfg dsp_driver=3'' and save the file.
+  - [[:access_the_batocera_via_ssh|Open a terminal]] and run ''batocera-save-overlay''.
+  - Reboot

   - Replace the second digit with your audio number. For instance, if it is ''audio.device=0,3'', then according to our example it would be ''audio.device=0,4''. The following text doesn't particularly matter, that's just the label it shows in EmulationStation.
   - Reboot, and if your audio still isn't working then try ''audio.device=1,3'', then ''audio.device=2,3'' and so on.
+===== Not all of my speakers are being used =====
+Ensure you have selected the right audio profile in **MAIN MENU** -> **SYSTEM SETTINGS** -> **AUDIO PROFILE**.
+For instance, a 5.1 surround sound setup would want to use the "SURROUND 5.1" profile:

 ===== I have sound in emulators and the main menu, but not during video previews =====

 This is more likely to be a hardware fault. Replug the cable, try a different cable, using a different interface (like 3.5mm analog audio instead of HDMI), etc.
+===== How do I diagnose my audio cutting out? =====
+While running a game, SSH into Batocera and run ''%%pw-top%%''. One line will be for ''alsa_output'' (depending on the emulator) and another line will be for the emulator (in most cases, ''retroarch''). Look at the ''ERR'' column, if both are increasing this indicates an issue with underrun audio frames. This can be solved via increasing the audio latency, choosing a more optimized audio backend or reducing the overall CPU usage.
+===== My audio device is not appearing in the list of available audio outputs on Raspberry Pi =====
+Try using the fake kernel mode setting instead of the full one as a workaround.
+In ''/boot/config.txt'', comment out the ''dtoverlay=vc4-kms-v3d'' and uncomment the ''dtoverlay=vc4-fkms-v3d'' lines. It should look like this:
+<code>
+# Enable DRM VC4 V3D driver on top of the dispmanx display stack
+# Preferred 'Full' Kernel Mode Setting (KMS)
+#dtoverlay=vc4-kms-v3d
+# Optional 'Fake' KMS for displays that won't work with 'Full' KMS
+dtoverlay=vc4-fkms-v3d
+</code>
+Using the fake kernel mode setting may introduce performance issues. It is preferable to instead figure out the root cause of the issue instead.
