Audio glitches on almost every core

TanyaEleventhGoddess commented 1 year ago

Description

ROMs audio stutters horribly on most cores

Expected behavior

Sound clear at least as much as the correspondent emulator

Actual behavior

Audio glitches if not an outright cacophony, sometimes no audio at all. Audio sounds distorted, as if sampled with an incorrect sampling rate or something

Steps to reproduce the bug

Use a regular audio daemon on Linux such as pulseaudio or pipewire
Run retroarch
Run a ROM with the following cores: bsnes, nestopia, mgba
Enjoy

Bisect Results

Difficult to say, I remember retroarch version on buster (1.7.3) worked properly, I'm certain on bullseye (samve version) libretro-mgba had said problem, from bookworm (1.14.0) it happens on every core

Version/Commit

libretro-mgba 0.10.2+dfsg-1
libretro-bsnes-* 094+git20220807
libretro-nestopia 1.52.0+20230102.gitcb1e24e
Retroarch 1.14.0

Environment information

OS: Debian Bookworm, Linux 6.1

Edit: Caused by run-ahead on some cores

You might want to check your audio sync settings. VSYNC can mess things up. https://forums.libretro.com/t/perfect-audio-video-synchronization/12072

Also check your frameskip settings and all the options under Latency. Pressing START on the menu items will reset them to their default.

Gotta thank you for your advice, after disabling vsync the subsequent cores started working properly:

Nestopia
Snes9x

Still some cores seem to have audio issues and it seems to depend on performance requests:

bsnes-mercury-performance (still stuttering)
bsnes-mercury-balanced (no audio)
bsnes-mercury-accuracy (no audio)
mGBA (audio stuttering horribly)

Edit: for Snes9x seems to still happen occasionally on some games (No audio on pocky and rocky (USA) on first run, proper audio on core reboot)

Hi,

Can you try to provide some log ? Did you try to make some test using another audio driver ?

Also you might try to update RetroArch using your own compiled latest stable version so that you can use latest updated cores from the online updater.

Thank you.

Thank you.

Log generated just now while running Lamborghini American Challenge with bsnes_mercury_performance with no audio, I trimmed lines describing my CPU, GPU and screen resolution

I trimmed lines describing my CPU, GPU and screen resolution

Why did you remove them ? It can be useful information for troubleshooting.

Also, you should provide some log with audio enabled.

Thank you.

Try either the GLCore or Vulkan drivers?

Privacy. It's old hardware though

I don't know how to activate Vulkan, either way I found out it wasn't the issue

Seems the issue is run-ahead (latency reduction), after resetting the configuration I found out removing it made all cores work properly and without any issue, thus audio wasn't distorted anymore. Disabling vsync also helped.

What's weird about run-ahead is that it's effect on cores remains after disabling it and rebooting retroarch 1-2 times, at the third attempt everything seems fine

Noone is going to fault you for running RetroArch on a potato. If anything, you'll get praise :wink:

Looks like we have the performance hit highlighted in the docs, so I believe we can close this.

The higher the number of frames you are going to run ahead of emulation, the higher demands it places on your CPU.
