Re: Smart 5.1 function not working on VIA VT1708S with *three* jacks on mainboard

["Viliam Kubis" <viliam.kubis@gmail.com>]

But my speakers only come with two jacks for input. One for the front  
speakers and one for rear speakers. So I cannot connect the speakers to  
all three jacks. I have compiled alsa with --with-debug=full configure  
option to see which pins it has auto-parsed:

HDA Intel 0000:00:14.2: PCI INT A disabled
HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16
ALSA hda_codec.c:4408: autoconfig: line_outs=1 (0x1c/0x0/0x0/0x0/0x0)
ALSA hda_codec.c:4412:    speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
ALSA hda_codec.c:4416:    hp_outs=1 (0x1d/0x0/0x0/0x0/0x0)
ALSA hda_codec.c:4417:    mono: mono_out=0x0
ALSA hda_codec.c:4420:    dig-out=0x20/0x0
ALSA hda_codec.c:4428:    inputs: mic=0x1a, fmic=0x1e, line=0x1b,  
fline=0x0, cd=0x1f, aux=0x0

However in function smart51_get, the following condition

if (ctl & AC_PINCTL_IN_EN
     && !(ctl & AC_PINCTL_OUT_EN))
{
	printk(KERN_INFO "*** PATCH on=0 in via_smart51_get()");
	on = 0;
}

will never be true, so smart51_get will always set  
*ucontrol->value.integer.value to 1. (printk line will not execute)

Smart 5.1 control gets created and appears to be "working". However  
surround output does not work.
