Choppy soundwith all emulators

I dont see PulseAudio. I google to see where it might be with no luck. The audio menu does not show me much, and i dont see under installed packages. Should I install it?

The Audio menu should show you (at the top) if the Audio is using ALSA or PulseAudio.

Should I install it?

No.

@mitu

Is the audio menu the speaker icon near the top? If so I see neither. I right-click and go to properties and nothing there either

mitu · 12 Sept 2021, 05:35

@rasp_renegade Are you using the desktop to check the Audio ? I was referring to the Audio menu in the RetroPie system from EmulationStation.

@mitu

OH! Sorry. It is ALSA.

I tried to enable PulseAudio, but ALSA is still displayed at the top. I even tried to reset to defaults with no change in the audio.

Are you running EmulationStation from the desktop ?
Having PulseAudio running may cause the sound to be choppy, so you shouldn't try to enable it. It may be running, but not detected by the audiosettings script.

@mitu

Correct. Desktop runs at startup, then i launch emulationstation from the CLI. This is how it was running before the update messed up the audio

mitu · 12 Sept 2021, 06:35

@rasp_renegade This is not a supported configuration. Please run EmulationStation from the console, without the desktop, and see if you still get the same issues.

@mitu

Very cool. I changed startup option from Desktop to the console. The sound is back to normal, but now the game speed/ audio is twice as fast. What happened there?

mitu · 12 Sept 2021, 07:57

@rasp_renegade are you sure it's not a US/EU ROM version issue (60hz vs 50hz) ? Did you change anything recently in the emulator settings ? What emulator/system are you checking with ?

rasp_renegade · 12 Sept 2021, 17:16

@mitu

I have atari2600, all MAME, C64, NES, SNES, Sega32x, N64. ROMS all US. Keep in mind that all emulators and ROMs were fine before the update, except for N64.
The nice thing is now N64 runs perfectly where before it was choppy video and audio.

I made no changes to video output at all, just played with audio but set all back as I was testing.

With booting to the console I get:
60 FPS, 16ms

Just for kicks, I switched back to boot from desktop to get:
7 FPS ,143 ms

What is the expected FPS?

Could it be that all emulators beside N64 are Libretro/RetroArch emulators ? This might indicate an issue with your RetroArch configuration.

If you resolution is running at 60hz, 60 would be the expected FPS for an emulator running at full speed.

How can I tell? Just to check I went into the RetroArch config menu and selected reset to defaults

Where can I see the setting in hz. I only see screen size

You can telll which emulator is running in the runcommand launch screen - if the emulator name is starting with lr-, then it's a libretro/RetroArch emulator, otherwise is a standalone emulator.

Just to check I went into the RetroArch config menu and selected reset to defaults

That's not advisable, especially if you enabled 'Save Configuration on Exit' in RetroArch. RetroArch's defaults are not always suitable for a Pi4, the RetroPie installation script will set the correct defaults.

If you resolution is running at 60hz, 60 would be the expected FPS for an emulator running at full speed.

If you open up the runcommand launch menu, you'll see the current resolution

@mitu

There is such a thing as a stupid question, and I just tossed two at you. LOL

I see the problem here. I am running liberto and have 0hz!!! What can I do the fix that?
N64 is also using Liberto but it does indeed show a setting for 60hz n/a (148 Mhz , phsync, phsync, unpreferred , userfef, driver)

How can I revert the RetroArch default reset?

Not sure I fully understand - but if you are talking about the video mode selection, you just press the select video mode menu and remove any selected video mode.

How can I revert the RetroArch default reset?

RetroArch has a few configuration files - see here. Each one of those configuration files should have a default file named retroarch.cfg.rp-default which you can use to copy over any non-default retroarch.cfg. You can probably look into each system's config folder and reset one of them, then test to see if it works.

I see no files named "retroarch.cfg.rp-default" in any of the system folders, or even in the "all" folder

@rasp_renegade I see you're still running from the desktop env - as I said, this is not supported.

Should be retroarch.cfg.rp-dist.

I dont see this one either anywhere. ??

Sorry I attached the wrong screenshot. I have been bouncing back and forth to try to find any indication of what is going on. Have a look at these

Notice one is not showing a video mode at all.

Should be one at least in /opt/retropie/configs/all/.

Sorry I attached the wrong screenshot. I have been bouncing back and forth to try to find any indication of what is going on. Have a look at these

the latter screenshot looks fine, the former shows a broken video mode selection. Rename the /opt/retropie/configs/all/videomodes.cfg file and try again.
