Public bug reported:

I got a Eee Top et1610pt with Windows preinstalled. I plugged in earphones when 
in windows first installation process (because of annoying music from speaker). 
I shot down the computer and installed Ubuntu 10.04 and only sound from 
headphones works. Speakers don't work when earphones are unplugged.
Going through https://help.ubuntu.com/community/SoundTroubleshootingProcedure :

Output step 3: http://paste.ubuntu.com/495370/
Output step 4: http://paste.ubuntu.com/495372/

I've tried to mute and unmute different things in alsamixer to no avail.

The solution is this:
hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 0x2

That makes sound behave normally. The only thing is that this has to be
set at every boot, so I put it in /etc/rc.local

This should of course not be necessary to do.
