 +===== My audio is randomly cutting out, and/or is distorted, on my RPi but only when using the headphone jack, and not the HDMI audio output ===== 
 + 
 +This is a very specific situation. The RPi seems like it overflows the audio buffer seemingly at random with the default audio drivers and latency. This can solved by either: 
 +  * Increasing the audio latency as above (some Pis can do this with just 96ms, others require significantly higher settings like 256ms which is obviously not desirable) 
 +  * Switching the audio driver to ''tinyalsa'' (this will end up breaking HDMI audio output) 
 + 
 +=== Via batocera.conf === 
 + 
 +Add ''global.retroarch.audio_driver=tinyalsa'' as a new line to your ''system/batocera.conf'' file. 
 + 
 +=== Via RetroArch's Quick Menu === 
 +To switch the default audio driver for Libretro cores: 
 +  - Run a game that uses a Libretro core. 
 +  - Press ''[HOTKEY]'' + {{:wiki:south.png?nolink&20|South button (B SNES)}} to open the RetroArch Quick Menu. 
 +  - Press {{:wiki:east.png?nolink&20|East button (A SNES)}} twice to exit to the main menu. 
 +  - Navigate to **Settings** -> **Audio** -> **Output** -> **Audio (Audio driver to use.)** and switch it to ''tinyalsa''
 +  - That's it. Simply changing this setting saves it. You can exit out of the emulator now. 
 + 
 +If the setting keeps going back to ''alsathreaded''/''alsa'': 
 +  * Use the ''batocera.conf'' method 
 +  * Disable any configuration overrides you might be using 
 +  * Disable any core overrides you might be using 
 +  * Disable any folder overrides you might be using 
 +  * Delete any overlays you might be using 
 + 
 +<WRAP center round info> 
 +This only works for Libretro cores, which is most of the systems that can be emulated on the Pi anyway. Other emulators either require advanced knowledge on changing their audio configuration, don't support the ''tinyalsa'' driver, aren't affected by audio cutting issues or would experience audio cutting issues anyway.

 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.
 +
 +===== 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.]]
