- | ==== My audio is consistently cutting out, irrelevant of what my system is doing ==== | + | ===== 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 '' | ||
+ | |||
+ | === Via batocera.conf === | ||
+ | |||
+ | Add '' | ||
+ | |||
+ | === Via RetroArch' | ||
+ | To switch the default audio driver for Libretro cores: | ||
+ | - Run a game that uses a Libretro core. | ||
+ | - Press '' | ||
+ | - Press {{: | ||
+ | - Navigate to **Settings** -> **Audio** -> **Output** -> **Audio (Audio driver to use.)** and switch it to '' | ||
+ | - That's it. Simply changing this setting saves it. You can exit out of the emulator now. | ||
+ | |||
+ | If the setting keeps going back to '' | ||
+ | * Use the '' | ||
+ | * Disable any configuration overrides 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, | ||
