I have read about a similar issue in the forum, and the solution was to install the pulseaudio driver.
Before you try, back up your setup!

sudo apt install pulseaudio pulseaudio-utils

@fredthelifeguard said in Audio Issues HDMI:

Built From: Image found on Raspberry Pi SD Card Imager

Which image are we talking about - RetroPie or RaspiOS Did you install any additional drivers or run additional scripts for the PiCade hat to work ?
Please post your /boot/config.txt file.

@dvojkaa for others there is this topic
https://retropie.org.uk/forum/topic/35350/no-audio-on-raspberry-pi-5/8

and it seems to work for him so i will try the same a write here again what happes

@mitu I am good to go as well. Thanks for the fix.

Please add some info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

As far as Linux (and RetroPie) is concerned, your 'headphones' are just an USB audio card - disable the onboard audio and they should be come the default audio card on the system.

@mitu i discovered that the file i was trying to play had H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
codec

i tried playing a video from really old times whose pixel layout was the exact same as my spi display 320x240 codec of that file was Xvid this time it didnt play anything it just crashed

@LeatherWing Thank you for the confirmation. The fix has been merged now.

@ModernPie Your config.txt have gpu_mem=64512. Maybe i am wrong, i believe this setting it is not necessary for a RPi4. Except that, 65MB for gpu memory is very low value .

@windg

I figured this out after wrangling with my Samsung firmware.

It was trying to automatically adjust the signal.

In my TV settings it had to be set to PCM. In ES default / hdmi / hdmi worked.

It happened after a background firmware update I wasn’t informed of, hence my utter confusion over cause.

The clue was that after switching to my Apple TV, same issue presented itself.

I take back any suggestion it was a Retropie issue.

The thing that really sent me for a loop was that for some reason the emulation station navigation clicks immediately became inaudible (but if you crank the volume you can hear it).

This is still an issue, and I’m unsure if it’s TV/ Retropie or combination of issues. The games, playback of snaps, etc. still sound fine / normal volume.

It is not significant enough to take much of my attention.

@mitu

I've already done that, a number of times.

There's something more complicated going on here.

I attempted a completely fresh install to track my progress better step-by-step.

It's here: https://retropie.org.uk/forum/topic/34489/continued-sound-issues-some-kind-of-bug

There seems to be:

A bug somewhere in the RetroPie audio script since 4.8 (whatever update coincided with the ".asoundrc is no longer being used" message).

Why would raspi-config generate .asoundrc when we should be using /etc/alsa/conf.d/99-retropie.conf? Why multiple config files for the same thing?

Something kind of bug or interaction with omx player.

I think most of those who are posting with lvl0 volume mixer issues who aren't helped by your guide are stumbling because they have omx player enabled.

You should change the Audio Device in EmulationStation's settings to one of the entries listed by aplay. If you the option doesn't show up in the menu, then edit es_settings directly and fill in the AudioDevice there.

front:CARD=Audio, DEV=0
USB Audio, USB Audio
Front Speakers

surround21:CARD=Audio, DEV=0
USB Audio, USB Audio
2.1 Surround output to Front and Subwoofer speakers

surround40:CARD=Audio, DEV=0

@dominoman2 said in Changing audio output from 3.5mm Headphone to USB Headset, using RetroPie Menus <tag>audio</tag>:

When I run the scripts I have to restart EmulationStation for the sound output changes to take effect

I guess that for EmulationStation to pick up the changes you need to modify the audio settings for the sound to be re-initialized, but for emulators it shouldn't be a problem.

@levitatingGuru Hey, I am wondering how you went about installing the kms driver? I am trying to also resolve the screen tearing but can't figure it our for the life of me. I have adapted the config.txt but I have read I have to install the KMS kernel 5.4 or something like that? is that correct?

Please provide the rest of the info requested in https://retropie.org.uk/forum/topic/3/read-this-first.
Add the config.txt file content between code tags (```).
