[alsa-devel] [PATCH - hda intel conextant 1/1] Fixed microphone mixer for HP Compaq Presario F700 Added conextant patch for Hewlett-Packard Company Device Subsystem id - 103c:30ea

[Jacopo De Simoi]

I can confirm that this patch applies to HP dv2700 subsystem 103c:30d6 (at least with 
-	{0x17, AC_VERB_SET_AMP_GAIN_MUTE, AMP_IN_UNMUTE(1) | 0x03},
+	{0x17, AC_VERB_SET_AMP_GAIN_MUTE, AMP_IN_UNMUTE(0) | 0x03},
 ). 

Node 0x14 supports multiple connections to 0x17 (0x01) and 0x1d (0x00); 0x1d is apparently not working; 
Also, I don't understand if 0x15-0x18 are working. It doesn't do anything here, but it might be stuff from the expansion slot (?)
