need help dell Inspiron 3501 gen 11 LA-K034P

[SYSLAN]

flash both IC, go to bios setup, write service tag, save then choose one of the three models (3501).

Following the instructions, still no audio. I tried also with a new OS as recommended by another user, nothing.
2 things to consider for future reference:
1. Windows won't detect any audio device as installed, like if there wasn't a Cirrus or Realtek in the mobo, it doesn't exist, no driver to install if there is no device to install the driver to.
2. I noted that when I configured it, I had no audio option in BIOS, but after a BIOS update it appeared. Before and after the update there was no audio.

Sadly I think that I'll give up since the client is a little anxious over their laptop.
Thanks for the help, I really appreciate it!

Were you able to go into the Bios setup and edit the service tag and model number? If you do that too, there must be a hardware problem (sound ic).

I can boot using an external drive, so that fixes the USB issue, but still no audio and no m.2.
