does the laptop specification or user manual mention that it can support 5.1 playback ?
http://www.intel.com/support/motherboards/desktop/sb/CS-034198.htm 2-channel audio The green line out jack, located on the back panel, is designed to power either headphones or amplified speakers only. Poor audio quality can occur if passive, non-amplified, speakers are connected to this output. 6-channel audio The back panel audio jacks support up to six speakers and are retaskable using the audio controller interface. Audio jack retasking is a feature that allows a jack to support more than one function. For example, the pink audio jack can support microphone input when the system configuration is set to stereo mode, 2-channel, and as Center/LFE or Rear Surround, when set to 6-channel mode. -- 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/1254287 Title: [LG S1-P331P, ALC880, Speaker] Speaker do not work after using headphones Status in “alsa-driver” package in Ubuntu: Incomplete Bug description: If I am listening to music with headphones and then shut down the computer and unplug the headphones, when I boot ubuntu the next time, no sound can be listened to from the speakers and I have to explicitly select speakers in sound settings. Ubuntu should determine automatically that no headphones are connected and select speakers.
