Hacked PC - random sounds playing (sh.itjust.works)

My fellow penguins,

I have been pwned. What started off as weeks of smiling everytime I heard a 7-10s soundbyte of Karma Factory's "Where Is My Mind" has now devolved into hearing dashes and dots (Morse Code) and my all-time favorite, a South Park S13: Dead Celebrities soundbyte of Ike's Dad saying, "Ike, we are sick of you talking about ghosts!"

It's getting old now.

I feel like these sounds should be grepable in some log somewhere, but I'm a neophyte to this. I've done a clean (secure wipe >> reinstall) already, the sounds returned not even a day later.

Distro is Debian Bookworm. So how do I find these soundbytes? And how do I overcome this persistence? UFW is blocking inbound connection attempts everyday, but the attacker already established a foothold.

Thank you in advance. LOLseas

Or... ya know... not. Hence me wanting to track this down. Hence this post. Mental health is very important though. Everyone agree to take care of themselves, mkthanks.

Ik it's a long shot and wasn't really what you were asking for. I've just had family with schizophrenia and it's important to like... Idk leave the door open to it sometimes

I have a friend that struggles with delusional disorder, so I'm no stranger to such disorders. But I assure you, having had to listen to these 7-10s soundbytes, find out the sources (Karma Factory/South Park/Morse Code) for weeks now... of sound mind (didja see what I did there lol), it's real and it sucks.

Still hoping someone can point me to a log file I can grep against for sounds.

Okay ah see to me it was almost a tell that you already knew the sources, didn't know you had to figure out where they were from.

Okay I'm trying to think:

Attach a debugger to your kernel, break right when you hear the noise, and then do a full memory dump. Then share it with us here. If you have to be crafty, write a script to send a break right when sound emits. You might need a second computer for this.

Sending a dump of entire system memory seems incredibly unsafe, to say the least.

I've just got the one PC. E-recycled all my Thinkpads, I'm now running an AMD Ryzen 9 16-core CPU, 64GB CL14 RAM (1:1 IF) full-ATX rig. And I love her.
