7.2-stable review patch. If anyone has any objections, please let me know. ------------------ From: Yu-Hsiang Tseng commit 2a8ee6897302ca12ff39e8eb180503956797c60c upstream. The Higole F9B is an Alder Lake-N mini PC with a 7" touchscreen and an ALC269VC codec (subsystem ID 0x10ec111e). Its DMI strings are all "Default string", so the SSID is the only way to identify it. The internal speaker is silent out of the box. The generic parser assigns DAC 0x03 to the speaker pin 0x14 and DAC 0x02 to the headphone pin 0x15, but the speaker only reproduces what DAC 0x02 plays, whatever its connection selection says. Checked one path at a time, only the gain of DAC 0x02 and the mute of pin 0x14 change what comes out of the speaker. User space only knows the path it was told the speaker uses, so selecting the speaker turns the path that actually reaches it all the way down. Route both 0x14 and 0x15 through mixer 0x0c (DAC 0x02), which is what ALC290_FIXUP_MONO_SPEAKERS already does. Tested on the device: the speaker plays.
