Using the dmidecode database from https://linux-hardware.org/ shows that the chosen DMI strings also match the following 2 laptops which also have a rt5645 codec: Insignia NS-P11W7100 https://linux-hardware.org/?computer=3DE092FFF8BA04 Insignia NS-P10W8100 https://linux-hardware.org/?computer=3DAFB6C0BF7934 All 4 hw revisions of the LattePanda board have "S70CR" in their BIOS version DMI strings: DF-BI-7-S70CR100-* DF-BI-7-S70CR110-* DF-BI-7-S70CR200-* LP-BS-7-S70CR700-* See e.g. https://linux-hardware.org/?computer=3DD98250A817C0 Add a partial (non exact) DMI match on this string to make the LattePanda board DMI match more precise to avoid false-positive matches.
