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?

hdmi_safe=1 is equivalent to:

hdmi_force_hotplug=1 hdmi_ignore_edid=0xa5000080 config_hdmi_boost=4 hdmi_group=2 hdmi_mode=4 disable_overscan=0 overscan_left=24 overscan_right=24 overscan_top=24 overscan_bottom=24

You can add

hdmi_force_hotplug=1 hdmi_ignore_edid=0xa5000080 config_hdmi_boost=4 hdmi_group=2 hdmi_mode=4 disable_overscan=1

instead of hdmi_safe=1.

@t3stin I don't know, I use a stock config and this is not set on my system. If you just want to test the sound, there's a command line speaker-test command you can use. Or download an .mp3 and play it from the command line with cvlc.

@radji Ran into this while I was researching my own struggles outputting dual monitors from my Pi 4. I found a way to get it done - I'll spare you the walkthrough if that's okay but it involved booting the desktop environment first with xrandr installed and the displays configured there - then rigging the thing to autostart emulation station from there on top of that environment. Long story short, I took a huge performance hit, even the gen. 4 consoles started dropping frames and chopping audio. I was super proud to get it working after many failures and posts online saying it couldn't be done, but unfortunately it just wasn't worth it in the end. Most people suggest an HDMI splitter and now that I can see how rough it can be on the system to make this work - just don't do it is my advice. Maybe it's a moot point for you by now, but FYI for anyone else down the road. Go with the splitter.

@152adam Just tried it in bin/cue format and the soundtrack is working now. So it seems likely the .chd format is the source of the issue with the cd audio. Wonder if anyone else has noticed this problem.

What settings do you have in the Sound section in Emulationstation ?

Thanks all for your help. I found a good image for the Pi0 and dont have any problems now :)
