@Lolonois Yes, I see it with "amixer". I never used this command. I will remember to check that everytime.

Now i'm working on the fully broken system :

I removed pulseaudio and pipewire. Now I can select vc4-hdmi-0 or vc4-hdmi-1 in Retropie audio menu and in raspi-config menu.

here is the amixer output :

Simple mixer control 'PCM',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Mono: Front Left: Playback 255 [100%] [0.00dB] Front Right: Playback 255 [100%] [0.00dB] Simple mixer control 'HDMI',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Mono: Front Left: Playback 255 [100%] [0.00dB] [on] Front Right: Playback 255 [100%] [0.00dB] [on]

Sound still not working, with hdmi-0 or hdmi-1 and PCM or HDMI in ES menu. sliders working but no sound. This time "MASTER" is stuck at 0%. I understand why now.

When I go in audio Retropie-setup Menu I can see an error during one second :

lvl0: Audio manager error: unable to open SDL audio : Alsa Couldn't open audio device: Device or ressource busy.

After there is the two hdmi choices and the working "Mixer - adjust output volume" Option.
I try to "Reset to default", reboot, nothing changes.

In raspi-config, 6-Advanced Options, A7-Audio Config, there is "No audio systems installed".

vc4-hdmi-0 and vc4-hdmi-1 are still availlable in 1-System Options, S2 Audio.

I updated SDL1 and SDL2 dependency packages in RetroPie Setup. Nothing changes.

@zipino82 Yes, I can see it, thank you. Please also provide the rest of the info requested.

Thanks guys, that was exactly the problem. I followed the thread @windg provided, and it worked first time. I really appreciate you guys

@jamrom2 said in Noted lr-mame2003 performance issues after RA update to 1.9.5:

As of now, I set up lr-mame2003 as I need it with a few options, saved the retroarch.cfg once and turned off "save on exit". It's now pulling the video parameters of every game I throw at it based on what I have listed in the file I posted to you.

i guess i'm not totally clear on what you want to achieve. retropie at the basic level has a global retroarch.cfg (/all/retroarch.cfg) which has the baseline settings for all libretro (lr-) emulators. then beyond that there's per-directory configs (eg /mame-libretro/retroarch.cfg) which by default point to an input_remapping_directory, and then defer back to the global config, as you've shown above.

then additionally you can have per-game overrides, per-core overrides, and gamename.ext.cfg overrides. to set up any of these you don't need to ever set 'save on exit' on. it's probably safest to manually create them, actually.

so i'm not sure exactly what hierarchy of configs you want to end up with, and what you currently have.

Ultimately... to not have this happen the next time I choose to upgrade any core part of the build... LOL. I thought I was doing something good by updating RA from 1.8.8 to 1.9.4 then .5. But my build has apparently become so convoluted that I disrupted areas I wasn't aware of.

I'm going to say by adding in the scriptmodules I added more issues than I was aware of. Just the idea that I turn off a shader and I loose performance means something is crossed somewhere.

I'll keep poking around my config files and hopefully find out what's causing some of this. What you and mitu offered was insightful and helped a lot.. but I think this is something that will ultimately leave me with a "it's working good enough" scenario.

@sirhenrythe5th no problem :) it will be the default in future images at least.

let me know if you get any audio drops! the gameplay should keep going but the audio cuts out for a second or two.

@gazbusola

My issue clearly had to do with pulseaudio, which I have no use for (at least for now!) on my current Raspberry Setup.

Your issue might have to do with the different HDMI modes. Have you looked into the config file for all the HDMI settings?

@o0mr-robot0o said in Audio devices not found.:

it's soldered to a custom pcb that holds the compute module etc.

If you replaced the CM with the 3b+ board, I wouldn't expect this to still work.

Should I edit that line to "yes"?

Sure, why not, but I don't see how it would work if you don't connect any of the audio outputs from the 3b+ to your device's speakers.

Update with more information. So if I switch to a different TV the audio problem vanishes and it works fine without unplugging and repluging. However a different issue shows it self on the new tv. Emulation station flashes black randomly it seems to occur more during heavy scrolling and subsides if i am not moving around in emulation station at all. But in game everything works fine. Thoughts or ideas?

Update: I tried these instructions: https://raspberrypi.stackexchange.com/questions/53408/automatically-connect-trusted-bluetooth-speaker/76288#76288

Installed BaReinhard's repo and rebooted. I was able to connect to the AirPods when it launched back up and for a brief moment sound actually came through from youtube on the AirPods and I thought I may have fixed it, but then it cut out again after about two seconds. I'm getting the feeling that it connects and then gets disconnected almost immediately for some reason. Indeed, looking at bluetoothctl it seems to connect then disconnect to the devices immediately.

E.g. it will say:

sudo bluetoothctl
Agent registered
[CHG] Device D0:03:4B:ED:E5:20 Connected: yes
[CHG] Device D0:03:4B:ED:E5:20 Connected: no
[CHG] Device D0:03:4B:ED:E5:20 Connected: yes
[CHG] Device D0:03:4B:ED:E5:20 Connected: no

in quick succession, continuing on with this "yes/no" pattern. It does not seem able to maintain a connection.

Don't know if that sheds any light on the problem.

@common763 when you power off the Pi... Are you just killing the power, or using a safe shut-down script.

Or even a Mausberry?

@mitu No, I am outputting at 1080p. Which was a pain. Whenever I try to change the resolution in raspi-config it just backs me out, so I had to set the resolution via terminal /boot/config.txt.

@challenger2010 said in No sound at all in Mortal Kombat 2/3/Ultimate:

I remember long ago that with Midway games in Mame, you had to go into the service menu of the game and turn the volume up.

This is right as the default volume is quit low on these machines.
But in the end you should hear something (very quit...but no silence at all), and the author mentoined that he allready used the volume control in the service menu ("F2").

Just to mention it: AdvanceMame has this great feature "auto level volume" which prevents me from running to the volume control on my setup as i dont have a remote control for my 2.1 logitech-soundsystem :)

Sorry for posting in an old thread, but I'm having this issue myself. Exactly as described in the OP. Only happens with Bonk's Adventure, both the US and Japanese versions. I'll try OP's fix, but I wonder if this is something that could/should be looked into?
