If anyone has any objections, please let me know. ------------------ From: Luis Gerardo Lopez Hernandez [ Upstream commit d933955c456e0573b40eae4f72a3af37ab1c15c3 ] The Acer Aspire AL16-31P (Intel Alder Lake-N, Realtek ALC269VC, PCI/codec SSID 2782:1718) has its internal speakers wired to pin 0x1b, but the BIOS marks that pin as not connected (0x411111f0) and only exposes pin 0x14 as the speaker. As a result the internal speakers are silent while headphones, HDMI and Bluetooth work. This is the same layout as the Infinix Y4 Max and MEDION E15433, which share the 0x2782 subsystem vendor. Reuse their fixup, which configures pin 0x1b as an internal speaker and limits the internal mic boost. Tested by booting with snd-hda-intel model=2782:1705: the fixup is picked, pin 0x1b is used as a speaker output, the internal speakers work, and they are muted when headphones are plugged in.
