if your Dell Studio 1458 have dual HP Out at Ext Right - node  0x19 and 0x1b
, the latest driver seem put them into line_out  instead of hp_outs

hda_codec: ALC665: BIOS auto-probing.
autoconfig: line_outs=2 (0x19/0x1b/0x0/0x0/0x0)
   speaker_outs=1 (0x15/0x0/0x0/0x0/0x0)
   hp_outs=0 (0x0/0x0/0x0/0x0/0x0)
   mono: mono_out=0x0
   inputs: Internal Mic=0x12 Mic=0x1a
