I too confirm that the http://people.canonical.com/~diwic/temp/alsa-intel-hda-optiplex-dkms_1.0.23_all.deb fixes the problem. My laptop is Asus K52DR and the devices as reported by 'aplay -l' are:
vita@vita-laptop:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: ALC259 Analog [ALC259 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: Generic [HD-Audio Generic], device 3: ATI HDMI [ATI HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0
Also alsamixer now correctly shows the 'headphone' control. Thanks for fixing this bug!
