   - 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.   - 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.

   - 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]''.   - You can also diagnose some sound issues with the ''alsamixer'' sound mixer that is available when pressing ''[Ctrl]''+''[Alt]''+''[F4]'' (text-mode sound mixer).

 +==== 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.   - Replace the second digit with your audio number.

 +===== 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:

 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. This is more likely to be a hardware fault.

 +===== 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.

 Using the fake kernel mode setting may introduce performance issues. It is preferable to instead figure out the root cause of the issue instead. Using the fake kernel mode setting may introduce performance issues. It is preferable to instead figure out the root cause of the issue instead.

 +You can use [[:launch_a_script|Batocera's scripting capabilities]] to do so. [[:launch_a_script#batocera_scripts1|Scroll down to find an example related to audio settings.]]
