installed opensuse10.3 on a y510 ideapad. sound was detected as snd-hda-intel, and for the most part it works. for example, i don't get an lfe slider in the sound apps. also don't believe all of the sound features are working (i did not boot vista to see what it did.) the right-hand orange volume control brings up the mixer but the values don't change.
when searching for a solution, the ubuntu folks have said to append model=lenovo-ms7195-dig to the sound options statement. when i tried this, the speakers began to squeal, the system locked up and i had to pull the battery to restart it.
it seems there are several different alsa options for lenovo machines. does anyone know which one option does work for this laptop?
