thank you so much for this guide, i followed the steps from this site
and now i have sounds o my acer 6920 again!
the only problem is that it is much quieter than i was expecting, is this normal for linux? my only other problem is that the volume control next to the time and date on the "start bar" does work, when i click it i get this message - "No volume control GStreamer plugins and/or devices found." is this normal? do i need to get a new app to fix this? i am very new to this OS so the simpler the solution the better.
