using hda-emu with the patched alsa-info

send: NID=0xf, VERB=0xf00(get_parameters), PARM=0xd(amp_in_cap)

the driver muted the connection from node 0x02

send: NID=0xf, VERB=0x360(set_amp_gain_mute,I:L#0), PARM=0x80
send: NID=0xf, VERB=0x350(set_amp_gain_mute,I:R#0), PARM=0x80

and unmuted the connection from node 0x03

send: NID=0xf, VERB=0x361(set_amp_gain_mute,I:L#1), PARM=0x0
send: NID=0xf, VERB=0x351(set_amp_gain_mute,I:R#1), PARM=0x0

you can use hda-verb to mute the connection 0x02 at node 0x0f
