If you hear audio crackling or if games are slow like 55fps, you may need to use 44.1KHz instead. The default rate, 48KHz, should be OK in most case. For example: audio_device = "hdmi:CARD=PCH,DEV=0"īut please bear in mind that you need to stop retroarch before editing the configuration file. The config key for the audio device is audio_device. To list those cards, you have use the command line interface and type one of these commands: aplay -Lĭiscard all samples (playback) or generate zero samples (capture)ĭefault ALSA Output (currently PulseAudio Sound Server)Ģ.1 Surround output to Front and Subwoofer speakersĤ.0 Surround output to Front and Rear speakersĤ.1 Surround output to Front, Rear and Subwoofer speakersĥ.0 Surround output to Front, Center and Rear speakersĥ.1 Surround output to Front, Center, Rear and Subwoofer speakersħ.1 Surround output to Front, Center, Side, Rear and Woofer speakers Switching audio device manually Listing your audio cards

You need to restart RetroArch for this change to take effect. In recent versions of Lakka, you can go to the Audio Settings and switch the Audio Device using the left and right keys. So if you get no sound, it means you need to switch to another card. Lakka can use only one of these cards at a time. For example, on Cubieboard2, the first card hw:0,0 will output through jack, while the second card hw:0,1 will output through HDMI.

I’ve read elsewhere that even though the card has the Linux partition with the Lakka install, the rest of the capacity. It works, and I’m running all my roms off of a usb-3 external hard drive. Some boards such has Cubieboard2, Banana Pi, Cuboxi, or Hummingboard have two or three audio cards. I bought a 128gb micro SD, formatted it FAT32, flashed it with Lakka using the Pi installer, and then installed it on my Pi 4. Configuring audio has become tricky on devices with more than one audio card.
