You need a stereo audio amplifier between the Pi’s analogue audio out and your speakers.
If you’re ok soldering something like the following should work and could be powered from the Pi’s 5V.

The autostart file does not work like that.
Instead each command runs under its own subshell simultaneously.
Therefore, your chromium command doesn't know those variables even exist.
To fix:
Put those 3 commands in a bash script (*.sh) file, make it executable, and put the path to the script in your autostart file.
Example script at /home/pi/Desktop/...

If your intent is to reduce the potential for SD card corruption, then you should look at Adafruits tutorial for a "Read Only Raspberry Pi" -

It is not perfect, but it will stop all logging and seems to survive most inadvertent power failures.

Journald does potentially consume a lot of disk space compared to the traditional text based logging done by rsyslog. In addition, since both are enabled by default in Raspbian, there is the implication that you will end up with redundant waste.
Fortunately, that's not quite how it is configured; from /usr/share/doc/systemd/README.Debian:
To enable ...

Here are some thoughts about what is possible in conjunction with your idea. You want to run a program on a remote device and show its output on the RasPi and also accept its input (keyboard, mouse) also on the RasPi. Because the program is running on the remote device it can only use its resources: managing input/output (except the human interface), memory, ...

Just to be clear you can't run Windows programs on the Pi.
You can use a program like VNC to let the Pi act as display/keyboard for the Windows machine.
Raspbian includes RealVNC although you would have to install the realvnc-vnc-viewer on the Pi (it is not installed by default AFAIK).
You would need to install VNC Server on the Windows machine.
There may ...

On the very first boot of a virgin Raspbian image there is running a script that you can find in /boot/cmdline.txt before booting first time. This is from Rasbian Buster Lite 2020-02-13:

Adding to M. Rostami's question, make sure your cable is firmly connected to your monitor. Also, make sure to check the screen resolution that was set from raspi-config.

It would be the config.txt on your raspberry pi's /boot partition:
# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1
As it said themself, uncomment this line would solve your problem.
# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1
In addition, check this ...

There is no need to "find the full size of the filesystem" - by default fdisk will use all space (and will indeed suggest the size). The only precaution is the need to ensure the correct partition START is selected.
If you REALLY want to use parted you can use a command like
cat /sys/block/mmcblk0/size
to get the size (you would need to use the ...

After so much searching I figured that I had to add this after #!/bin/bash
### BEGIN INIT INFO
# Provides: my-service-name
# Required-Start: $all
# Required-Stop:
# Default-Start: 2 3 4 5
# Default-Stop:
# Short-Description: your description here
### END INIT INFO
Got it working now. Thanks
