Comment 109 for bug 418627

I tried the option model=acer instead of model=will. I don't find that the sound is too high. (I didn't try eadphones).
The sound is very ugly, but by changing the subwoofer's volume (with alsamixer command) which is too high, the sound becomes good.
with model=will, I did not have the opportunity to change the subwoofer's volume. And the sound seems the same after change. So, according to me model=acer is a better choice.
(I'm pretty sure that earlier I tried model=acer and get no sound.)
