    Unable To Get Sound Working to External Speaker on HP TouchSmart 320 on Ubuntu 11.04

    This is an HP TouchSmart 320, model number 320-1200m. I'm using Ubuntu 11.04, fully-updated.

    Hardware information:

    root@hp320:/home/mpower# aplay -l
    **** List of PLAYBACK Hardware Devices ****
    card 0: Generic [HD-Audio Generic], device 0: STAC92xx Analog [STAC92xx Analog]
    Subdevices: 1/1
    Subdevice #0: subdevice #0

    root@hp320:~$ cat /proc/asound/card0/codec#0 | grep Codec
    Codec: IDT 92HD91BXX

    Sound to headphone jack works properly, but sound to built-in speakers does not work. I have installed Windows, and with Windows 7 installed, all audio hardware works properly, so this isn't a hardware fault.

    I've looked at https://help.ubuntu.com/community/HdaIntelSoundHowto and have been unable to find my card in http://www.kernel.org/doc/Documentat...dio-Models.txt .

    I have tried adding almost every conceivable model in the line "options snd-hda-intel model=MODEL" line I added to /etc/modprobe.d/alsa-base.conf.

    Update 2011-11-09 2:31 PM PST: I've gone to Control Center -> Sound Preferences to attempt settings that make sound work. The "Hardware" tab shows one device: "Internal Audio 1 Output / 1 Input Analog Stereo Duplex." There are two output profiles listed in the selection box at the bottom of the tag: Analog Stereo Duplex and Analog Stereo Output. Neither cause sound to emit from the speakers.

    I've also run alsamixer on the command-line and ensured that everything is set to maximum and nothing is muted.

    Update 2011-11-09 5:15 PM PST: I've replicated the exact same symptoms in 11.10.
