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

What is your exact question for the topic ?

[hughp]

@mitu a raspberry pi with a logitechis21 set of speakers and sub my question is how to get the volume slider unstuck it resets to 0 but i get volume in game i need help getting the slider unstuck

[Retrodade]

@hughp I have had this issue many times with newer retro pie.
I never could fix it, hope yours gets solved
With HDMI new seemed fine, but I use the headphone jack with speakers, only solution for me was stick with older retro pie.
it's not a solution, I know
hopefully your post will shed some light on this headphone jack no sound issue

[hughp]

@Retrodade i have sound in games =just the volume slider is stuck so i have to use the controls inside the machine

[mitu]

@hughp You've provided almost no information from the list in https://retropie.org.uk/forum/topic/3/read-this-first. What Pi model ? What RetroPie version and how did you install it ? Your speakers - how are they connected to the Pi ?

[hughp]

@mitu raspberry pi 4 retropie 4.8 used raspberry pi installer speakers use headphonejack

Hi, I have the same issue.
Plus, I have this error while loading each game.

Orange Pi zero 2w 4gb, Dietpi OS.

Hi, I have the same issue.

Post the settings for audio that you have in EmulationStation (Card and Device). What version of DietPi ? Are you using PulseAudio/PipeWire for audio ? Is the audio working when you start a game/emulator ?

Please run the following commands and post the output:

amixer
aplay -l
aplay -L

@mitu Hi Mitu, thank you for the response!

I am running Dietpi OS v9.8.0 Armv8 Debian GNU/Linux 12 Bookworm
Device model : Orange Pi Zero 2W (aarch64)

Pulseaudio is installed, I've read elsewhere that it should connect to Alsa.?

I do have sound through HDMI output, no matter what settings in ES.
ES, Retroarch and Mupen64plus are fully functional, apart from the error.

Extra info, proper hardware/software setup for the sound on Orange Pi Zero 2w might be incomplete. If so, and this is an OS issue, i'll move back to the Dietpi forum :)

Hope this will already help identifying the issue:

I was trying every setting yesterday and gave up. I gave up when it was set to: Default/Master

I logged in to double check and... No more error.

Since the default Mixer control for the default audio card is named Master , this is what you should set as Audio Device. As it turns out, you already found this is the working option.

[Arrafart]

@mitu thank you for clarifying. If needed on a different device, I now know how to check it and replicate.

[hughp]

@Arrafart i have this issue still and i need help its a black rasp pie 4 4gb running retro pie

[Arrafart]

@hughp for me it was finding the correct setting. Default/Master
Try to replicate what @mitu said above. I was lucky to reboot with the correct setting by accident.

I believe a reboot will be necessary ater each time you check it, but not sure.

Again, I was lucky and Mitu was right the day after.

No, a reboot is not necessary.

[hughp]

@mitu what do i need to do to fix my issue

[mitu]

@hughp Change the Audio settings for Card in EmulationStation to Headphones ?

[hughp]

@mitu its on headphones

[mitu]

@hughp No idea then. If the audio works in games, then the default device is set to headphone/analog on the system.

Please run the following commands and post the output:

amixer
aplay -l
