For comparison I have observed the Windows XP and SigmaTel Audio Control Panel for driver "SigmaTel 2/19/2007 5.10.0.5401":
Front Panel A. Headphones, B. Headphones, C. Mic A. "Device Connected: Front Speakers", "Device Connected: Headphones" B. "Device Connected: Center / LFE Speaker", "Device Connected: Headphones" C. "Device Connected: Line In", "Device Connected: Mic", "Device Connected: Rear Speakers" A is left-position jack, B is middle-position jack, and C is right- position jack. With Takashi's patch v3 the assignments do not line up with the above functions. It would be nice if Surround 5.1 is possible on Ubuntu however I can test that here or file a new bug, which would you like? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1195377 Title: [Inspiron 1420, SigmaTel STAC9228, Speaker, Internal] fails after a while or plug in and out headphones Status in “alsa-driver” package in Ubuntu: New Bug description: Regression from kernel 3.8.x to 3.9.x alsa drivers.
