I have an issue with a background cracking sound on the audio over digital only when using dolphin. It can best be described as listing to an old record where you have random pops and scratches.

Using a 5700u MiniPC with 32GB Ram.

Troubleshooting that I did:

HDMI, DP, USB C outputs all have this noise issue
Using the Analog out does not have this issue
Using a KT USB audio device does not have this issue

Tried several DVI/DP TV's and Monitors and the all have the issue

Using Batocera, or Windows with dolphin on the same computer does not have this issue

Someone else reported the same issue 2 years ago using the previous version of recalbox with the following system

Intel Desktop Board DH61CR
Intel Xeon 1225 v2 CPU
ASUS HD 6450s GPU

Switching the audio driver from Pulse to Cubeb will also resolve the issue.

But there's still an issue with switching to Cubeb. Recalbox doesn't save or reverts the driver back to PULSE, so you have to change the driver each time.

Is there some sort of resolution to the cracking sound issue?

Is there a way to keep the CUBEB driver change by modifying a confitg file etc..?

When I plug a PS4 controller (Original or clone) with a USB cable into either a PI4 or X86 version of recalbox. The controller is not detected. They work fine wired in other OS's on the same systems..

I can pair them fine via bluetooth, but not directly wired. Recalbox wiki/docs says that this is supported..

Is there some option to enable the wired DS4/PS4 controller support that I missed?

Rename the files as simple as possible like SM64 to "Super Mario 64" and "Knuckles Chaotix".

The scraper seems to have issues when there are extra characters etc. in the filename.

You could also manually make an entry in the gamelist.xml file and grab the artwork from here.

Issues with the N64 emulation using a Pi 4 on 9.1-Pulsar. I've double checked these games are working fine using Batocera & Retropie, just to make sure there wasn't some other issue.

Start Wars Rogue Squadron
Any Emulator won't start or hard lock the system (power cycle to restart).

Libretro Mupen64plus_Next = Sometimes works, sometimes crashes, usually when saving game state..

Resident Evil 2
Mupen64Plus Glide64MK2 = No 3D images / sprites, game only displays the background Images

Mupen64plus Rice = Screen corruption or Blank screen,

Libretto Parallel_N64 = Screen corruption or Blank screen,

Conkers Bad Fur Day
Will randomly cause the system to lock up

I'd still suggest trying using a different usb controller/Gamepad

How is the SN30 connected to the PI? is it USB cable or Bluetooth?

Here's some stuff to try, might not do anything at all.. but it's worth a try..

If it's the wired version. Turn on your PI and boot up, unplug the controller now press the Y button while plugging back in the SN30.
then see if works... Do the same but pressing the X button.

Y should set it to "switch" mode and X to "PC mode", the type of controller that it detects should change, when you do this, see if it makes any difference.

The retroarch part (when you're playing games) has lost the controller config, or has some sort of override that's being applied.

Usually taking a completely different USB controller and using that will get things working enough to start fixing things, worst case you can reset it all..

You'll need to reconfigure you controller and any other settings after the reset. (case type, network, internal/external storage overlock etc..)

@Khyron

In case someone ever asks the same question, the answer is

Hotkey+

A = Reset
X = Load SaveState
Y = Save SaveState

DPAD UP = INCREMENT SAVESTATE SLOT
DPAD RIGHT = FAST FORWARD
L1 = SCREEN CAPTURE

Have a similar issue with a couple 4:3 monitors and my main Panasonic TV, and it only seems to happen with a raspberry PI.

I've tried messing with the EDID parameters etc.. to get an under scan, but it never works right..

Quick solution is to use integer scaling for all games of the affected system, and you'll end up with the whole image visible and some under scan.

The best solution is to use a custom aspect ration, keep the integer scaling on, this will keep the image centered so you don't need to play with those setting to center anything.. make sure you start with the "core provided" then switch to custom and just knock off about 10% from the width and height that appear as default values.. You can also play a bit to get more screen coverage while the image still looks good..

Once you're done save the changes as a "game override", so each time the game loads the parameters loaded..

Only issue with this method is you need to do this for each game..

@engenoir

il devrait avoir une option de langue dans le "core options" de retroarch

https://docs.libretro.com/library/flycast/#core-options

Does anyone know all the default button mappings for Mupen64Plus GLide64MK2 with a RPI4 including all the hotkeys (save state, rumble etc..)

@Pecee1946

Thanks! but if I could press F7.. I wouldn't need the virtual keyboard.

I've searched around and couldn't find an answer to this.
I couldn't find any instructions if the build of scummvm in Recalbox had the Virtual keyboard. Is there one? if so what activates it?
