This is what I did to fix my audio via HDMI problems:

THIS IS PART OF A RETROPIE MASTER FIX PDF I AM PUTTING TOGETHER FORT SELF USE

Even after several released of RetroPie, several people are still reporting audio issues. It is also a common issue with Pi users altogether. Here is a quick fix I discovered after editing the config file.

2.1 a: Editing config.txt

Linux:

Linux location: /boot on PI (root or boot)

Methods

SSH via WIFI with Linux through CLI on a local Linux box and network

Windows location: / (root or boot) on PI or USB root (PI Micro SD)

Methods

You can SSH via Putty/WINSCP] and enter command cd /boot to find config file.
You can insert the PI Micro SD USB into a hub/USB adapter and connect it to your PC. The config file will be sitting in the root of the USB.

Editing tools recommendations:

Linux: VI/VIM/NANO (NANO=gross)
Windows: Notepad++ (free)

2.1 b. Adding fix:

When you open the config.txt file, there are several settings hashed out. For those who are new to config files under a Linux distro, # means the option in that line is disabled. You can look for the lines below in the text file and remove the hash or just add this entire text to the end of the file:

#Audio issues over HDMI fix
hdmi_drive=2
hdmi_force_hotplug=1
hdmi_force_edid_audio=1

2.1 c. Additional Information:

The hdmi_drive=2 value may fix the issue as it is meant to force and only choose HDMI for sound.
An issue may still exist when switching monitors as audio formats may change form TV to TV. Enabling some forcing options fixed the audio issues for me. Here are the options and what they do. You can either enable one at a time or all at once.

hdmi_drive=2
o Chooses HDMI only over any other option and will transmit sound if supported.

hdmi_force_hotplug=1
o Pretends HDMI hotplug signal is asserted so it appears as an HDMI display is attached

hdmi_force_edid_audio=1
o Pretends all audio formats are supported by the display, allowing pass-through of DTS/AC3 even when not reported as supported.

If the issues persist, some Googling may help as well. That's how I got all this info.

@Roxsteady thanks for that. i got the sound working in the menu etc but not in games. I've done everything you suggested

cackmobile

@cackmobile solved. in retroarch config i changed hw:0,1 to hw:1

@cackmobile Thank you for solving this. None of the other threads I've read actually detailed the same problem, or listed the solution. Running Jessie on a laptop and don't have sound in games, but perfect in menus and scrape videos? This is the solution.

Hi!
I'm having trouble in this part. I also try almost everything.
I built a mini console with raspberry zero, a small screen and I'm using audio amplifier pam8403

for example:
I entered in config.txt hundred times.
I went to audio setup and set 3.5mm

Any suggestions, please?
Other question. I tried to measure signal at GPIO13 (where the audio amplifier is connected) and I don't have signal. Is this so because it isn't somehow activated in software?

@cackmobile Don't find this line. could you mind to guide me, please?

I have seen that a lot of people are suffering from the same. I had the same issues and headaches. I kinda made it work. On games run OK. I only have Sonic for Megadrive, the only Game I kinda have :). I also have the lines for adjusting the sound on your keyboard and joystick, using Hotkey + ANY KEY. I will add it later.

I will past here my config.txt. I hope it helps.

Some settings may impact device functionality. See link above for details

uncomment if you get no picture on HDMI for a default "safe" mode

#hdmi_safe=1

uncomment this if your display has a black border of unused pixels visible

and your display can output without overscan

disable_overscan=0

uncomment the following to adjust overscan. Use positive numbers if console

goes off screen, and negative if there is too much border

#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

uncomment to force a console size. By default it will be display's size minus

overscan.

#framebuffer_width=1280
#framebuffer_height=720

uncomment if hdmi display is not detected and composite is being output

#hdmi_force_hotplug=1

uncomment to force a specific HDMI mode (this will force VGA)

#hdmi_group=1
#hdmi_mode=1

uncomment to force a HDMI mode rather than DVI. This can make audio work in

DMT (computer monitor) modes

#hdmi_drive=2

uncomment to increase signal to HDMI, if you have interference, blanking, or

no display

#config_hdmi_boost=4

uncomment for composite PAL

#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

Uncomment some or all of these to enable the optional hardware interfaces

#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

Uncomment this to enable the lirc-rpi module

#dtoverlay=lirc-rpi

Additional overlays and parameters are documented /boot/overlays/README

Enable audio (loads snd_bcm2835) <- this part is very important.

@n00bi3 Please surround file contents/code with code tags ( ``) at the beginning and at the end of the paragraph. What you quoted for sound settings is the default setting for the RetroPie image (dtparam=audio=on), so it's not something new.

It might not be new or the answer for the whole life existence thingy, but it may help someone ;)
