Dell laptop has a series model to use the same codec but different subsystem ID.
At the same time they happens the white noise by login screen and headphone;
for fixing them together, I only can add these IDs to FIXUP function ALC292_FIXUP_DISABLE_AAMIX,
then try to solve such the similar issues.

Codec: Realtek ALC3235
Vendor Id: 0x10ec0293
Subsystem Id: 0x102806dd
Subsystem Id: 0x102806df
Subsystem Id: 0x102806e0
