I have meanwhile also found a workaround for ubuntu 11.04
1. installed linux-alsa-driver from repository ppa:ubuntu-audio-dev/ppa see http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu/pool/main/l/linux-alsa-driver-modules-2.6.38/
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa sudo apt-get update sudo apt-get install linux-alsa-driver-modules-$(uname -r)
note: at the moment there are only packages for kernel 2.6.38-8 available
2. opened file /etc/pulse/daemon.conf and replaced
a) entry
; enable-lfe-remixing = no
with
enable-lfe-remixing = yes
and b) entry
; default-sample-channels = 2
default-sample-channels = 6
3. opened file /etc/modprobe.d/alsa-base.conf and added
options snd-hda-intel model=basic
at the end of this file
4. opened file /etc/modules and added
snd-hda-intel model=basic
5. Then I rebooted laptop.
Subwoofer is now working unter ubuntu 11.04 (with same rich, full sound as under Windows).
