ubuntu 11.10, no sound, toshiba satellite p100
i have installed ubuntu 11.10 on to a toshiba satellite p100 laptop. the drivers for the sound card seem to be installed, in so far as there are no errors showing and speaker/volume control are functioning correctly. neither built-in speakers nor headphones are able to output anything.
in the sound control applet there is no function to configure the sound card hardware/driver.
unable to determine spec of hardware either through applet or toshiba website. previously running winxp media centre edition.
any help out there?
