Public bug reported:
This issue is nearly identical to that reported in Bug#673051, but on a
different ASUS laptop model. Like the ASUS G73JW, the ASUS G73JH has a
built-in subwoofer. This subwoofer works perfectly under Windows, but
does not work at all under Ubuntu Linux 10.10. As a result, sound coming
from the laptop speakers sounds thin and tinny on Ubuntu, instead of the
rich, full sound under Windows.
