Beginner questions

[rvs11]

Hello,

First of all, thank you very much for the work you provide here.
I'm a Moode and Linux newbie.

I have a few questions.

The installation and setup went smoothly so far (Raspberry pi 4b 8GB).
10.1" TFT Touch 1280x720 from Waveshare - works

1.
Now I wanted to output the audio signal to the 3.5mm jack plug for testing purposes.
In the configuration I couldn't select this option (only the two HDMI).
In the forum I found a note that the kernel must be set to firmware legacy.
Now the audio output on the jack plug works, but the 10" TFT remains dark.
What could be the reason?

I plan to use a Hifiberry DAC2 Pro.
Which device must then be selected under I2S?
Hifiberry DAC+ PRO?
Or do I just have to select "hifiberry-dacplus-pro" under DT overlay?
Or do you recommend another DAC?

2.
Radios:
Most pre-installed radios do not work.
I get an error. Failed to decode HTTP Status 404
However, when I copy the URL into the browser the radio works.
When I try to integrate other radios I get the same error.
Internet connection is of course available.
What could be the reason?

3.
Which remote control should I use?
IR or radio
What can you recommend?

4.
I would also like to use hardware buttons for operation.
(Are there ready-made keypads available to buy?)
I found the option under GPIO.
What do I have to enter here?


5.
Power button
Found a "guide" in the forum.
Got into /boot/firmware/config.txt under GENERAL
dtoverlay=gpio-shutdown,gpio_pin=3,active_low=1,gpio_pull=up
registered.
Button is connected between GND and GPIO 3 (pins 5 and 6).

Unfortunately that doesn't work.

I know there are a lot of questions.
I've searched the forum for several hours but unfortunately I had no success.

Thank you for your help

You can try turning on Local Display in Peripheral Config but there is no troubleshooting support for HDMI video when running Firmware mode for Integrated audio. Its a hack thats only meant for Headphone-jack configs w/o attached display.

Hifiberry DAC+ PRO?

What driver (overlay) does the manufacturer specify for DAC2 Pro?

I'm not able to reproduce this but the symptom suggests some sort of network issue external to moode software.

3.

I have no experience with IR remotes. I only use a smartphone and the nice WebUI.

I have no experience with GPIO button hardware.
