Lakka No Audio Problem

Libretro Lakka
,
#1

Installed Lakka on an old PC with NVidia Graphics card and I am having issues getting the sound to work through either HDMI or other means. The Lakka gui does not scroll through audio devices. I have tried testing audio with no luck. Not to familiar with Linux and would appreciate any advice would be appreciated.

Just an FYI, logs should be posted using the “pre-formatted text” method.:grin:

You should try to connect by SSH then edit the configuration file

systemctl stop retroarch
nano /storage/.config/retroarch/retroarch.cfg

change audio_device to hdmi:CARD=NVidia,DEV=0 and restart RA with systemctl start retroarch.

If it does not work change audio device to hdmi:CARD=NVidia,DEV=1 and so on.

Don’t forget each time to stop RA before editing the configuration file.

HDMI audio Maxwell GPU should work according to the nouveau feature matrix.

But to get best performance it will better to have AMD or Intel HD GPU as they have better support with the open source driver not the fault of nouveau team which is doing an amazing work !

The HDMI sound worked briefly and then stopped. I switched to default:CARD=PCH and I now seem to be able to get sound from the AUX port and it will allow me to select output devices from the GUI. When attempting to switch to hdmi in the GUI the problem persists and removes the capability to switch within Lakka. Any additional ideas are welcome but at least I have some sound at the moment.

Please try to provide some log with createlog.

Thank you.

Thank you for the log, we should have also the dmesg log, it will be useful.

The HDMI sound worked briefly and then stopped.

Which HDMI audio device did you use ?

[4.2][PC] Sound Output (RESOLVED)
#8

I believe it was hdmi:CARD=NVidia,DEV=3

#9

So if you stop RetroArch and put for the audio_device in the configuration file.

audio_device = "hdmi:CARD=NVidia,DEV=3"

Then restart RA.
