Pi3 no audio

RetroArch Linux devices
#1

I can’t seem to get audio on my pi3. The games play fine but no sound. Programs outside of Retro play audio fine. Any ideas?

#2

Which audio driver are you using Alsa ? PulseAudio ?

Setting Tab > Audio > Audio Enable is on ? Setting Tab > Audio > Audo Mute is off ?

You can try also to change audio device in Setting Tab > Audio > Audio device by press left or right key.

Using Alsa now but I’ve tried the other drivers. Mute is off and I’ve tried different devices. I also changed the volume from 0 but nothing has worked thus far. Thank you for your help.

Did you tried this?

Audio not working on some TVs

Some TVs send a wrong EDID saying that HDMI audio is not supported while in fact it is. You may need to force HDMI audio by uncommenting this line in the config.txt:

hdmi_drive=2

#5

I don’t see that line in my config file. I’ve attached it…I must be missing it?

#6

Try to add it then :wink:

#7

OK I added that line in the HDMI section but still no audio. Any other ideas?

#8

I’m having the same issue. Fresh Lakka install on my Pi3. No audio… I plugged in the card to my computer and uncommented the hdmi_drive=2 line in config.txt and booted the pi back up. Still nothing

aplay -L also only shows this below. Nothing about HDMI – is there supposed to be?

null
    Discard all samples (playback) or generate zero samples (capture)
default:CARD=ALSA
    bcm2835 ALSA, bcm2835 ALSA
    Default Audio Device
sysdefault:CARD=ALSA
    bcm2835 ALSA, bcm2835 ALSA

That sucks. Hopefully we can figure this out.

#10

Try adding:

hdmi_force_edid_audio=1

to your config.txt

That worked for me :slight_smile:

#11

Still nothing…

I’m glad you got yours fixed though!

#12

Also try adding: hdmi_force_hotplug=1

#13

I have that line already. Here’s what I have…

Force HDMI even if unplugged or powered off

hdmi_force_hotplug=1

hdmi_force_edid_audio=1

hdmi_drive=2

#14

Oh, that should be:

Force HDMI even if unplugged or powered off

hdmi_force_hotplug=1 hdmi_force_edid_audio=1 hdmi_drive=2

#15

OK I changed that and still nothing… I attached to file if you don’t mind checking just to be sure.

#16

Still no audio. Tried changing drivers and that didn’t help either.

#17

Can you try to provide some log ? Try to launch RA with :

retroarch --menu --verbose >> log.txt 2>&1

And the information is in the log.txt file.

Thank you.

#18

Sorry new to this but I figured out how to get a terminal by using Putty and getting in via ssh. I run the command but cannot locate the log.txt file?

#19

The file is where you launched RA. You can open it with an editor nano, vim or emacs ? Otherwise use for example less log.txt and copy and paste it.

If you can’t succeed to open it, use filezilla or winscp to copy the file on your PC.

I have kodi on a micro sd card so I pulled it and searched the entire card and it could not be found. My set up is a pi 3, Openelec 7.0, and Kodi 16.1. I open it through program addons.
