 +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.

   - 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

Try a higher number if it's still cutting out, it should gradually get better.

 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.
 +
 +===== 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.

 +===== My audio device is not appearing in the list of available audio outputs on HP EliteDesk 800 G4 mini =====
 +
 +[[https://www.reddit.com/r/batocera/comments/17vdhcb/hp_elitedesk_800_g4_mini_hdmiaudio_problems/|Roll back to BIOS v2.14.01]], as later versions have bugs preventing HDMI audio from working properly in Linux.
 +
 +===== I need to automate something involving my audio settings =====
 +
 +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.]]
