I have an Acer Aspire 8942G laptop that contains the Intel 5 Series/3400 card. That card provides surround sound capabilities. When Ubuntu 10.04 is installed, it is configured as stereo, but sound comes out of only one speaker - the right front. If I'm given some help, then I will be happy to provide whatever is required to get this card working correctly.
I can follow terminal commands, although compiling software might prove to be a challenge for me - I'm not highly technical. I have enabled the ubuntu-audio-dev ppa, and have the linux-backports-alsa-lucid-server and linux-backports-alsa-lucid-generic installed.
Any help would be much appreciated.
Thanks,

I have a similar problem on my Acer Inspire 1830TZ with the same Intel graphics chip. But think yourself lucky, I don't get any sound!
