UPDATE/SOLVED: it was not related to the music player, after all.

I had presumed that libmpg123 error meant it was related to my mpg123 background music player, but it seems that's may be not the case.

It only happen on "random video" screensaver mode, I am unable to reproduce on either "dim" or "slideshow" screensaver modes.

...and, it happens now even with the music disabled. Now mpg123 is still installed on my RPi4 but when disabled it is never brought up during autostart.sh so now is just ES(-dev), and my video files (mostly which come from ScreenScraper).

Looks libmpg123 is also used by the vlc (which I do use on ES, as I have "use OMX player for screensaver" set to "off.")

Seems it is caused by (one or more) particular video files. I (backed up and) deleted half my gamelists (so their videos won't be played), and the error still occurred. Then I restored my backups, and deleted the other half the gamelists -- this time no error! I have narrowed it down further to a single game in my SNES playlist -- confirmed by removing all other entries so only that one plays when triggering screensaver, and then the error happens right away.

I tracked it down to a single bad video from screenscraper. Whenever the Pop'n TwinBee (SNES) video is played, the Illegal Audio-MPEG-Header error is displayed in console, in multiple, when exit EmulationStation.

This is accompanied by a visual glitch in the video playback (or freeze, depending on player) at about 0:16 seconds in, just past the halfway-mark. This also was visible on the video served from the screenscraper website.

I tagged the video in a comment on screenscraper.fr asking to re- generate their standardized video. A short time later, that request was granted and, after re-scraping that one game, the error is now resolved!

For curiosity: if you have this game, and have a video scraped prior to a few hours ago (about 2024-03-22 19:00 GMT), do you experience the same console error after playing its video on screensaver and, after re-scraping, is it also now resolved?

You still haven't said the Pi model you're using, as asked in https://retropie.org.uk/forum/topic/3/read-this-first. Can you please add that info ?

You need to configure the Audio:

first in the RetroPie system, by opening the Audio entry there and choosing Headphones as your audio output next in EmulationStation's menu, under the Audio sub-menu, choose the default card to be either PCM or Headphones.

@windg This worked great! Thank you so much @windg!!

@sleve_mcdichael ok, I was just making sure there wasn't somewhere obvious I was missing on handing fr HDMI to headphones. Or if there was a general location where this would typically be saved, such as in a config file somewhere. It may be easier for me to just install another separately from the beginning

@SuperFromND yeah I've been a fan of Ahoy for a while now. His video on Polybius is to go to video about the made up video game. Also his vids on very specifics In video games such exploding barrels are awesome

IMO (!!!) Kodi (which is great of course) is allready enough non-gaming-content for retropie.
I am not interested in any streaming of music at all on the Pi.
As said: IMHO

@jnbridges and you could always use something like this to get that arcade sound you were talking about.

@retropiecase you can scrape videos with Skyscraper, if that's what you mean: https://retropie.org.uk/docs/Scraper/#lars-muldjords-skyscraper

@buzz no, as i dont know if there is an issue with the script, or if there is a common issue with retropie settings that other run into with this using this script

[v2023.11] Released
Removed OMX Monitor from Settings + omxplayer wait from [autostart.sh] (Deprecated)

Thanks All for the Feedback...

@rommell76 Ah, I didn't know that. Good to hear you did get it working, though.

@retropie start with a specific % volume

mpg123 -f "32768" # Volume % "100"
mpg123 -f "29484" # Volume % "90 "
mpg123 -f "26208" # Volume % "80 "
mpg123 -f "22932" # Volume % "70 "
mpg123 -f "19656" # Volume % "60 "
mpg123 -f "16380" # Volume % "50 "
mpg123 -f "13104" # Volume % "40 "
mpg123 -f "9828" # Volume % "30 "
mpg123 -f "6552" # Volume % "20 "
mpg123 -f "3276" # Volume % "10 "
mpg123 -f "1638" # Volume % "5 "

@Rydo

Can I ask how you determined the following values?

/dev/input/jsX 0x3C 0x3E 0x2B 0x2D 0x70 0x71 0x69 0x6F

On a fresh RetroPie image using a wired Nintendo Switch controller, my button assignments do not match up to yours.

My device name is:

deviceName="BDA NSW wired controller"

So I'm curious how you determined those hex values.

Thanks,

David

The joy2key program is hard programed.
/dev/input/jsX means it is applied to all Linux joystick.
The hex escape codes are ansi keyboard codes for keypresses that overlay buttons in the order of 'left', 'right', 'up', 'down', 'a', 'b', 'x', 'y'

0x3C 0x3E 0x2B 0x2D 0x70 0x71 0x69 0x6F

I would suspect your buttons are backwards (Japanese style) so I would move the value around like this.

0x3C 0x3E 0x2B 0x2D 0x71 0x70 0x6F 0x69

@ghostshot1398 i dont know, since i dont use that BGM.
you will have to do a search for
MusicStateMachine.py if you are using WinSCP there is a file search tab that will work

if not give me a day and ill load up a clean load and i can do a little digging

@caver01

Correct when piping through the HDMI all is well with sound levels. The only reason I wanted to use the AV jack is so I could play Pandora with the TV off.

I cannot even install Firefox. ???

I got the image from from https://www.raspberrypi.org/software/operating-systems/

@lochnagar I know the music on Tomba II is glitchy and plays the wrong track on the default (and only emulator if on a pi) psx emulator. It’s old and buggy and hasn’t really been updated with any significance in a long time. But it runs very smoothly on low end hardware and runs most games just fine. There is no fix unless someone updates the emulator to fix said bugs.

RetroPie doesn't have any music in EmulationStation - are you using a 3rd party image ?

@freddyja script.zip is not avalaible, I can't use this guide.
