Choppy soundwith all emulators

rasp_renegade

Hello everyone!

As always, I am my own worst enemy. I had issues with my controls so I ran all updates. After that my controllers were back to normal, but the sound did not work at all until disconnecting the HDMI cable from TV. After that the audio was choppy. I played with every sound setting in the UI to no avail.

-I can watch movies or listen to music on the pixel desktop with no issues
-Every rom on every emulator has choppy sound, while the video FPS is normal
-Cooling is fine
-Voltage is fine

pi4 model B Rev 1.4
RetroPie 4.7.16
EmulationStation v2.9.6 RP
Canakit 2.5A
Sound output HDMI

EDIT: The TV is a 1080P, not 4K

Not sure which config file to upload if someone can direct me

@rasp_renegade Are you using a 4k tv? If so, you'll have to set the resolution to 1080p.

@darksavior
No it is a 1080P. Its old, there was not 4K yet.

rasp_renegade

@dankcushions It is not a 4k

Do you have the desktop installed ? If yes, then check in the Audio menu if you have PulseAudio installed, it is installed (nowadays) automatically if you install the desktop.

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.

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

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

rasp_renegade

@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.

mitu

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

@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.

rasp_renegade

@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

@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

@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.

What is the expected FPS?

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

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

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
