Not sure which version of RetroPie are you using (version 4.4 is too old to support the PI4), but out of the box I think HDMI sound should work using the 4.7.1 image.

Make sure that in the Audio settings in the RetroPie system you choose HDMI as output, then in ES the settings should be:
AUDIO CARD: Default
AUDIO DEVICE: HDMI

For OMX audio output, just use ALSA and it should work.

I successfully replaced the line

dtoverlay=vc4-kms-v3d

in my config.txt file with

dtoverlay=vc4-fkms-v3d

and now everything works perfectly! Thanks for the help @mitu

@mitu solution: create a script with the following:
#! / bin / bash
"apulse / opt / retropie / ports / lzdoom / lzdoom" ""

It doesn't work like the other games on the list, but it opens the traditional lzdoom text dialog, the wads should be hosted in ./.config/lzdoom

My user is "hollywoodarcade", so everything's located here: /home/hollywoodarcade/RetroPie

I'm guessing I'm probably in the wrong directory

I've enabled Pulse again for within EmulationStation.
It seems to fix my problem so far. I'll keep a close eye on this.

I had the same problem. The navigation sound work but with delay, i press bottom and the sound play 2 seconds later. The video screen saver is not heard. The volume control although it changes it stays at zero. But the sound in the games is good.
I have tried all the options of "Audio Card" "Audio Device", but the only one I hear something is heard with a lot of lag.
This happened to me after I had updated the Emulation Station. Before updating it worked fine.

Is there any way to fix it?

Hey hey, maybe, I have found the solution: In the MAIN MENU / SOUND SETTINGS / AUDIO CARD, I selected <DEFAULT> because the entry was null <>. Just below, in the AUDIO DEVICE, I selected <PCM>.

With this config, the error message disapeared. My config is: sound via a HDMI/VGA convertor, jack to mini-amplificator (RCA).

Great, no ?

@rc_cola
Once when I experienced problems with cd tracks on psx games, I experimented with different audio drivers. If you dig more and search the web, you will find some different opinions. I think one of the audio driver will synchronize with video and if you get frame drops or anything else can't keep it up, then audio starts to stutter. Changing the driver did resolve this problem, if i remember right. The audio wasn't no longer synchronized, but it sounded without problems and I couldn't tell anything wrong with it. It was only happening with cd tracks. So, in short, this could be one of the tradeoffs. I have no more details about this, sorry.

Btw, you may find more information if you search about these topics in generell, like sdl vs alsa. These are common in Linux. And just in case you missed this page:
https://retropie.org.uk/docs/Sound-Issues/ Note, they speak about older Raspberry Pi versions on this page.

@billybag said in Alsa Problem, I Think:

i cannot load any of my playstation games (i believe they are all PS2 games if that matters)

Yes that matters. Retropie cannot play Playstation 2 games. Only PS1.

Hi again,
Sorry about that, after entering amixer -i the output is amixer: Mixer default error: No such file or directory and entering amixer -l just gave the above error when I thought you said amixer -1,

And would you have any idea about how I would even read the boot/config.txt file

Thanks

@BuZz it said 0 added 0 updated when i ran it. I am going to put a backup image on as soon as i am done backing up my config folder.
