Based on this output, I think you'd need to set in EmulationStation the Audio Card to Device.

To get the name of the mixer (volume control), run

amixer scontrols -c Device

and choose the 1st entry and set it as Audio Device. For instance, in my case, the USB audio card is named 'Controller':

amixer scontrols -c Controller Simple mixer control 'PCM',0 Simple mixer control 'Headset',0

I would use PCM as the AudioDevice settings in ~/.emulationstation/es_settings.cfg:

<string name="AudioCard" value="Controller" /> <string name="AudioDevice" value="PCM" />

This should fix the audio not working (or the volume slider rather) in EmulationStation.

For Amiberry, I'm not sure why it's not working - maybe it's trying to use the 'default' card and it's not working ?

Try following the advice here and create a /home/pi/.asoundrc file containing

defaults.pcm.!card 1 defaults.ctl.!card 1

Based on information provided in another post, it appears that PowerBlock is not compatible with Pi 400.

Info from other post: "The PowerBlock provides power to the GPIO pins 2 and 4 switched via a power switch IC.
The Pi 400, though, cannot be powered via it's GPIO pins, see https://www.hackster.io/news/raspberry-pi-400-design-change-puts-an-end-to-battery-power-gpio-add-on-boards-770826a23ed9.".

Thanks for your response - very helpful.

I'm a stubborn SOB...do you think it would be possible to connect this (https://www.digikey.ca/en/products/detail/sparkfun-electronics/BOB-15100/9770720) to the PowerBlock to send power from the PowerBlock via USB-C to the Pi 400? I could then connect the relevant pins from PowerBlock to the Pi 400 (pins 5 and 6, I assume) and pins 2 and 4 to the BOB-15100 (USB-C adapter I linked to).

Alternatively, I may just have to purchase a regular Pi 4...

I want the external power button as I'm planning to put the Pi within a custom-built arcade. I bought the Pi 400 thinking this would be easier (with the built-in keyboard)....but I'm beginning to see that maybe that's not the case.

@bio_hazard1282 said in draStic on Raspberry Pi 400:

Turns out that I couldn't install it, is there a build of it for arm64?

No, there isn't. The binary provided by the developer(s) of DraStic is only for 32 bit ARM. Also note that we don't support Ubuntu on the Pi, so some things might not work correctly.

@mrpacman17

There is no response at all to the keyboard, I am not sure how it handles the Raspberry Pi400 built in keyboard. I would like to build a Bar top game system but I would like to search for the game in either the "ALL GAMES" section or my "FAVORITES" section. Also, I am undecided whether to go with a 6 button layout or a 8 button layout, and if I go with the 6 button layout, can I use those extra buttons for features like "LOAD/SAVE" Volume UP" "Volume Down" "ESC" ? Thanks for any help!!

You can add shortcuts to your gamelist that will start with an empty file, thus disabling the auto-loading. Some emulators already have a similar shortcut (+Start Amiberry, +Start Fuse), you can replicate the setup for others.

If you prefer working from the desktop, then you can leave RetroPie alone and just install the emulators manually on a Raspbian + Desktop image.

@retropieuser555 did you configured anything special? I've can't solve the garbled colors problem (beside this the game works).

I've tried the normal fallout version en de HD version. Both have the same problem.

@mth75 What are the settings in Retroarch.
Do I have to change anything in the audio-driver section?
My setting is sysdefault:CARD=USB

ATM I have sound in ES but not in the emulators.

@sirhenrythe5th

That's got it!

Nice one thanks

@chris3535 as @mitu said, I needed to go into the retroarch settings for lr-fuse and set the control 3 option to keyboard, works fine now.

@redpiperbob Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

Please provide more details of your set-up - which image you downloaded and so on.

@luckyluca said in Pi400 slow stuttery dremcast redream emulationI:

Regarding overclocking, do you know what the default gpu clock is for the pi400/pi4?

I think the default gpu_freq is set to 500 (Pi4), I assume is the same for Pi 400.

@mitu , I have a system set up with 4 controllers on my pi400 and would like to use the keyboard to search for the game that I would like to play, from the ALL GAMES list. Is there a way to do this ? I do not want to use the keyboard as a controller, only as a way to input for game selection. Thank you!!

Which emulator are you using ?

Then set the resolution via raspi-config or directly into config.txt, this will set the resolution globally, without the need to run tvservice. See https://www.raspberrypi.org/documentation/configuration/config-txt/video.md.
