My subwo0fer is not working on Ubuntu 11.10. Satellites are all working. It is part of a 5.1 Soundsystem. I've already googled and changed in the /etc/pulse/daemon.conf file these Variables and rebooted:
default-sample-channels = 6 (it was "2" before)
enable-lfe-remixing = yes (it was "no" before
Could it be possible, that I need a special audio driver? The soundcard is onboard on my ASrock 775i945GZ. If yes where can I get a driver for ubuntu? On Windows XP i use "Realtek high definition audio driver ver:R1.47" (from the ASrock product support site)
EDIT 1 [21.01.2012]
okay, i tried a bit more on my own. I found this website: link
I found out my audio chip is a Realtec alc888
I followed the instructions and added a line in /etc/modprobe.d/alsa-base.conf
I tried out many capabilities but none of them made my subwoffer work... there isn't even a subwoofer regulator in alsamixer!
Now I wrote:
options snd-hda-intel model=6stack-dig
but it is like in pulseaudio: sattelites working, subwoffer silent. I don't know what to do next... Please help!
EDIT 2 [21.01.2012]
okay, now i found out that there is a Linux driver for the high definition audio chipset from Realtek
I installed the latest one with sudo ./install
it took like 2 minutes then it finished.
I rebooted and now there are no sounds at all, there are no devices to configure in the Audio Options!!! And I can't start alsamixer!!!!! :O
Is it my fault? What did I do wrong? Did I forget something?
EDIT 3 [21.01.2012]
I wanted to reset also so i typed:
wolfi@wolfi-P4-3:~$ sudo /etc/init.d/alsa-utils reset
[sudo] password for wolfi:
and then it says:
sudo: /etc/init.d/alsa-utils: command not found
Did Realtek destroy alsa??? :O
