I checked hda-jack-sense-test and noticed it can take the command-line
option -d|--codec so I tried using that:
$ sudo /usr/bin/hda-jack-sense-test -d 2
Sigmatel specific "Analog Loopback: 0x00" verb ignored for the moment

Title:
No sound on speakers with HDA Intel, SigmaTel STAC9228, kernel 3.10
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
Ubuntu 13.04 Raring with linux 3.10.0-031000-generic from kernel-ppa.
Card: HDA Intel
Chip: SigmaTel STAC9228
After booting the 3.10 kernel there was no sound on speakers although
sound on headphones was fine.
Using the sound control GUI in Unity I was unable to find any
combination of options to enable sound to the speakers. Mute and
volume controls for the Speaker output device were set correctly.
I tried using "alasamixer" in a terminal and with "View: [All]"
noticed a mixer control "<Auto-Mute>" which was set to "Enabled". I
altered that to "Disabled" and speaker sound was enabled correctly.
