@ioortropie

Based on your previous answers it sounds like PulseAudio is not starting on its own.

Try systemctl --user enable pulseaudio in the terminal, and reboot.

If you still have no audio please post the output of pacmd list-sinks.

@oli said in Updated : New to retropie - no audio on Retropie using new Rasberry Pi 400:

The background music is only playing in the main menu.

RetroPie doesn't include any background music - are you using a RetroPie standard install image ? Please open a new topic and add your info, as requested in https://retropie.org.uk/forum/topic/3/read-this-first.

@xMoJox12 and the rest of the info ?

@DKarn No problem, there's no rush. Try other values for the Audio Card setting. Did you happen to notice what are the settings for your friend's installation ?

@quicksilver hey pal. Thanks for the advice! That did the trick. :) Cheers!

The specific emulator I'm having trouble with is mupen64plus-glide64
the lr-mupen64plus works fine but looks awful and won't load high res textures. The mupen64plus-glide64 emulator worked great until I had to reinstall everything for other reasons. No system hardware has changed since I've started this.

@simon123 I noticed two things, (1) you are using USB-powered speakers and (2) you didn't seem to have test the suggesitons about using alsamixer.
So I have some suggestions for you to try:

Are you connecting these speakers to the RPI itself using a USB port? This might be problematic because the RPI is known to not deliver much power through the USB ports, and I suspects speakers are power hungry. Can you try to power the speakers with a laptop or other source via USB but the audio from the RPI? Can you go to a console and type the following command to set the volume using alsa: amixer sset PCM 90% unmute. This sets the volume reasonable high so be careful with the noise.

After point 2 you should see something like this (volume set to 90%):

Simple mixer control 'PCM',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback -10239 - 400 Mono: Playback -663 [90%] [-6.63dB] [on]

Update: changing the advmane.rc from alsa to sdl fixed the no audio problem right away. Tested it by loading some games into the advmame folder, reloading emulation station and firing up the emulator with a game. Yes! Success! Thank you all. :-)

@janlopes really? Where are all the details of your setup? you even say you have tried things? What things? What did you edit? Which file? What did you type? Did you enable audio out properly? What do you have the volume level set to? What emulators have no sound? Which games? Which image? Official? Or a pre-loaded one? To enable others to help you please go back and read this

When you "have done" your post will contain the answers. Then and only then is it possible to even start to assist.

Thanks guys this has fixed my problem that night i asked. Got home from work and changed what you said and now everythings golden. thanks again.

Ok, so reinstall with 4.1

removed the hash from in front of hdmi_drive2 (now that I can see the config file) and that seemed to do it. That berryboot was the main cause like you said @rbaker , I will say this though: the config file looks way different than a regular raspberry pi one. But Ill see about any other changes in another thread. Moral of the story is skip berry boot if you can.

@pawpie when you set the overscan thing right there is 4 lines for setting the overscan for all 4 sides of the screen. You need to slowly increase/decrease the numbers until you get it perfect on your screen.

For the ps3 controller you need to go into retropie setup and go into the drivers section and setup the ps3 controller in there.

Just an update, I fixed the issue and now it's running beautifully. It turns out I was following the directions correctly, but I had no idea I had to remove the #. If I hadn't asked, I wouldn't have known so thank you guys for all your help!

@Pirate

Ditto I have this when using a USB DAC, all other emulators are ok but no audio on any N64 ROM

So I believe the issue is that emulationstation won't allow the video from mplayer to play over it. I've tried adding --ontop to the line in order to have it play over emulationstation, but that program always seems to be over mplayer, and I can only hear the audio of the video after emulationstation starts.
