In RetroArch set the audio output device to default:CARD=Headphones to route the audio output to the 3.5 mm jack. These lines must be in this order and no other config lines should be between them. If you are missing the audio output device for the 3.5 mm jack, following lines have to be added to config.txt to enable audio output via the 3.5 mm jack: dtoverlay=piaudio Staring from Lakka 4.0 add following line to config.txt: dtoverlay=vc4-kms-v3d,composite=1Īdd following lines to config.txt: enable_tvout=1 Here are examples for 240p mode: Raspberry Pi 3Īdd video=Composite-1: to cmdline.txt right after quiet (separate these statements with a space). Since Lakka version 3.5.1 it is possible to use CRT output. So the board’ll not use the HDMI sound output. If you are using a HDMI to VGA adaptor on a Raspberry Pi 1 or 2 and you want to use the jack output for the sound you have to write in config.txt on the first partition of the SD card: hdmi_ignore_edid_audio=1 If your RPi is not booting while using an HDMI to DVI adaptor, please remove this line from your config.txt: hdmi_drive=2 You may need to force HDMI audio by uncommenting this line in the config.txt: hdmi_drive=2

Some TVs send a wrong EDID saying that HDMI audio is not supported while in fact it is. If you are using a HDMI to VGA adaptor on a Raspberry Pi 1 or 2 and you want to use the jack output for the sound you have to write in config.txt on the first partition of the SD card: hdmiignoreedidaudio1 So the board’ll not use the HDMI sound output. This file allows you to tweak a lot of things like framebuffer resolution, overclocking, audio, and is documented here Audio not working on some TVs On the first partition of your SD card, you will find a file named config.txt.
