There is an issue with headphones in 1001 kernel. The best solution is to update kernel (http://dev.i-random.ru/ac100/kernel/ or http://dl.dropbox.com/u/36754970/ac100/Kernel-11.19/index.xhtml)

In other case check this:

Download tool https://dl.dropboxusercontent.com/u/40761340/www/ac100/tools/alc-ctl
Download script https://dl.dropboxusercontent.com/u/40761340/www/ac100/scripts/dump_alc_regs.sh
'''Start playback'''
Change permissions and run script:
<pre>
chmod a+x ./dump_alc_regs.sh
sudo ./dump_alc_regs.sh > regs.txt
</pre>

You could check hp state yourself:
<pre>
wget https://dl.dropboxusercontent.com/u/40761340/www/ac100/scripts/sound_state_scripts-2011-11-17.tar.bz2
tar jxf sound_state_scripts-2011-11-17.tar.bz2
cp regs.txt sound_state_script
cd sound_state_script
./state.sh hp
</pre>

You will get something like this:
<pre>
HP state:

Reg 3e (000a - 1010)
11 0: Power On HP Out Left Volume. 0-Down, 1-On
10 0: Power On HP Outt Right Volume. 0-Down, 1-On

Reg 04 (0505 - 10100000101)
15 0: Mute HP Left Control. 0-On, 1-Mute
7 0: Mute HP Right Control. 0-On, 1-Mute
[12 8] 00101 (5): HP Output Left Volume (HPLV) in 1.5dB Steps
[4 0] 00101 (5): HP Output Right Volume (HPRV) in 1.5dB Steps

Reg 10 (0000 - 0)
3 0: Mute DAC Left Volume Output to HP L Mixer. 0-On, 1-Mute
2 0: Mute DAC Right Volume Output to HP R Mixer. 0-On, 1-Mute

Reg 1c (0748 - 11101001000)
1 0: DAC Left Volume Output to HP Left Amplifier. 0-Mute, 1-On
0 0: DAC Right Volume Output to HP Right Amplifier. 0-Mute, 1-On
9 1: HP Left Volume Input Select. 0-VMID, 1-HP Left Mixer
8 1: HP Right Volume Input Select. 0-VMID, 1-HP Right Mixer

Reg 0c (1010 - 1000000010000)
15 0: Mute DAC Left Input. 0-On, 1-Mute
7 0: Mute DAC Right Input. 0-On, 1-Mute
[13 8] 010000 (16): DAC Right Volume (0.75 db step)
[5 0] 010000 (16): DAC Left Volume (0.75 db step)
</pre>

Pay attantion to reg 3e
<pre>
Reg 3e (000a - 1010)
11 0: Power On HP Out Left Volume. 0-Down, 1-On
10 0: Power On HP Outt Right Volume. 0-Down, 1-On
</pre>
Looks like hp power is off (usually reported from 1001 kernel).

Checked workaround is to enable it:
<pre>
sudo ./alc-ctl /dev/i2c-0 w 3e 0c0a
</pre>

I made a script to tune alsamixer, but looks like is doesn't work.
