Re: First day with Raspberry Pi. How to use it?

The wpa_supplicant.conf file should have the following inside. blah blah blah IMHO, this is bad advice for a beginner. It's too complicated and fraught with the possibility of frustrating errors.

Re: Sound disappears when connected via hdmi

I have the same problem with my RPi 4 connected by HDMI to a Samsung smart TV.
The sound is there, but I need between 90 and 100% volume on the TV to hear it.

Is there an actual conversation here, because I can't understand a word of this.
What is "less" and "more"?

Re: LAN connection does not work on RPi 4

Well, I always do headless installations.
The only thing I do is add a file called ssh to the SD card.
And with ethernet connected, it always just works!
Once I'm in using puTTY, then I can run raspi-config and enable VNC, etc.
Then in RealVNC, I configure the wireless.

Re: LAN connection does not work on RPi 4

It's easy to get yourself in a muddle when you do things this way.
IMHO, from years of bitter experience, it's better to set static IPs in the router and not fool around with the settings on the RPi.

Re: Converting Arduino code to Python Code

Please excuse my ignorance - it's several years since I used Arduino.
But why don't you just connect the Arduino to a USB port on the RPi and run your sketch on the RPi?

Re: xrdp works until reboot

Been there, done that.
Eventually, I gave up fighting it.
Instead, use RealVNC which comes bundled with Buster.
You just need VNC viewer on your PC.

Have you tried shutting down, disconnecting the ethernet cable, then powering up?
This will remove eth0 from the equation.

And the lugs on the sides of the PS are really annoying if you're using a power board, because they protrude over the adjacent slot meaning you can only use every second one.

Re: Raspberry Pi 4 Thread - general discussion

I'm running buster on an RPi 4 4GB. The RPi is connected to a Samsung TV by HDMI cable.
In Chromium, when I try to stream, the pictures come through just fine, but I need both RPi and TV at 100% volume to hear sound.
Is there a way to tweak the volume up a bit?

Re: Raspberry pi doesn't get ip while ssh is enabled

With the standard configuration the Pi expects to get an IP address via DHCP. Windows 10 also expects to get an IP address via DHCP. So if you connect them together on the ethernet ports they are both going to 'ask for' an IP address but thete's no router providing an answer. So you'd need to eithe...

Re: Can't access Pi over WAN

I had this problem with a previous router. It would not allow "hairpin routing", so to access my website using its external IP address, I had to use a machine outside of my LAN. When I replaced my router, the problem went away.

Re: Backing up 32 GB SD card on Windows 10

IMHO, it's better to back it up onto an SD card using Accessories/SD Card Copier.
Then , if the SD card fails, you just slip in the backup card and you're away again.

Having said that, I do a nightly backup of programs and data to Win 10 using WinSCP
