It is found that pin 0x1c must be set to PIN_OUT mode to make the speaker work. This is weird - line-in pin 0x1c and speaker pin 0x16 seem to be unrelated. The codec differences before/after patch are: @@ Node 0x17 [Pin Complex] wcaps 0x40020b: Pin Default 0x41a6e130: [N/A] Mic at Ext Rear Conn = Digital, Color = White DefAssociation = 0x3, Sequence = 0x0 Misc = NO_PRESENCE - Pin-ctls: 0x24: IN + Pin-ctls: 0x40: OUT @@ Node 0x1c [Pin Complex] wcaps 0x40018d: Pin Default 0x41813021: [N/A] Line In at Ext Rear Conn = 1/8, Color = Blue DefAssociation = 0x2, Sequence = 0x1 - Pin-ctls: 0x24: IN VREF_80 + Pin-ctls: 0x40: OUT VREF_HIZ Unsolicited: tag=00, enabled=0 Connection: 1 0x24 Tests show that it won't impact (external) Mic recording.
