If I were you, I'd do the following:
1. Reload soundcard driver with no model specified (i.e. delete 
"model=basic" from modprobe.conf and reboot or do rmmod 
snd-hda-intel/modprobe snd-hda-intel model=auto). This will reset all 
mixers, so you'll need to enable Capture again in order for mic to work.
2. If headphones work, you are done.
3. If not, run HDA Analyzer, find "PIN 0x21" in the left sidebar. Look 
at "Output Amplifier" checkbox group and clear mute checkboxes. Then, 
switch to "AUD_MIX (0x0C)" in the same sidebar and adjust output volume 
(the same checkbox group). You should hear sound in your headphones.
4. If not, look at PIN 0x1a and do the same as at step 3.
5. If this doesn't help, file a bug report.

Valentine
