I was chasing an audio bug on Linux Mint. The LLM had me doing the heavy stuff: changing kernel version, editing grub, touching boot records. Then it started giving me the same advice I'd already tried, the stuff I knew didn't work.
Two hours in I gave up and googled it. Top result: a thread that described my exact issue. I jumped to the end. The answer was that on my specific laptop you have to shut it down, not restart, for the audio hardware to reset.
Before LLMs I would have found that in five minutes.
So how do you spot the spiral? The advice starts repeating. The fixes get more drastic (kernel, grub, boot) while your actual problem is probably something dumb and hardware-specific that only shows up in forum threads. The model is pattern-matching on "Linux audio broken" and serving you the generic escalation playbook. It doesn't know your machine. It doesn't know that one weird thread from 2022.
You gotta know when to get back to what you know. Search. Skip to the end of the thread. Let someone who had your exact setup tell you the answer.
