Super Collider spontaneous start .... ?

When my RPi 3 B+ ( Rasbian Buster ) first boots the audio is acceptably quiet.
When I check my email ( outlook.com ) , after ~ 1/2 minute the noise level goes way up .
It sounds the same as when Sonic Pi starts , so I surmise it is Super Collider starting .
Any ideas on preventing this ?

Maybe you've developed a hardware problem with your HDMI lead?
I'll pursue that. Works after modifying config.txt ,
but perhaps the edid sense wire (is there such a thing ?)
is defunct .

Earliest image that will boot RPi-4

From where may I download the earliest Raspbian version that will boot a RPi-4 . The reason being that I just remembered that when I first got a Pi 4 it booted ( from the image on the downloads page) just fine. No work with config txt needed. Since then something has changed in the OS that is incomp...

Re: PI 4 ( 1G , 2G , 4G )

Can't use system with no video. You can if you can ssh to it using PuTTY from your Windows system or JuiceSSH from your phone. With plain Raspbian adding a "ssh" or "ssh.txt" file to the partion that's visible to Windows will enable SSH. A tool like Fing will find a Raspberry on your network (if yo...

It seems to me that's what's wrong is the desktop is appearing as some sort of frameless sub-window within what would normally be the full-screen desktop, or bits of the fullscreen desktop have gone AWOL.

Re: Pi 4 initial experience .... 1G vs 2G vs 4G

Try a different monitor as a test. I'll try that today out of curiosity , but it won't help ( even if it works ) much , since I have several ( of the same ( no working ) ) Not sure what you mean by Android though. Perhaps something like this : https://smile.amazon.com/gp/product/B07SKGZSB2?pf_rd_p=...

Have your working and non-working SD cards been updated (sudo apt update && sudo apt full-upgrade -y)?
No .... BUT ... Yes it's weird. The 3B+ boots fine on them.
I'll try updating them on the 3B+ ............

I am curious because I have had problems getting
a working screen ( hdmi ) that I never had with other
models.( same monitor(s)) I see some others have
had similar issues, and (it seems) more so with 4 G
variant.
