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.
