Enabling surround sound on Ubuntu 9.04
Posted by Nishanth in Open source on May 9th, 2009
By default ubuntu 9.04 uses PulseAudio which use only 2 channels by default. I am using creative 4.1 speaker system . After installing Ubuntu I realized that only 2 speakers are working . After some googling I enabled the surround sound.
You can find the default configuration in /etc/pulse/daemon.conf.
sudo gedit /etc/pulse/daemon.conf
You can find a commented line ;default-sample-channels=2 in daemon.conf. Uncomment this line(remove ; ) and change this according to your surround system . For me its 4.1 so my entry is like below
default-sample-channels = 5
If it is 5.1 then entry should be like default-sample-channels= 6
You have to restart pulseaudio( kill the pulseaudio and run it again from run dialog) or restart your machine.

I am using windows XP since 2003. Last week I got an error and unfortunately it was XP Blue Screen of Death STOP Codes. The error i got was something like ” make sure you have enough disk space” and it looks so funny because I have 120 GB free space 
. Then i decided to move on to open source OS may be I am late but still ok.
Installed Ubuntu 9.04 and without any trouble Ubuntu auto configured almost all my devices. Had some problem in configuring BSNL broad band which i solved yesterday

Last couple of days I was trying to connect BSNL broadband in Ubuntu. I followed the instructions from ubuntu forums but all in vain. Finally I manually added the router ip address and gateway in /etc/network/interfaces and it started working
I had edited /etc/network/interfaces
sudo vi /etc/network/interfaces
and added below lines
iface eth0 inet static address 192.168.1.2 netmask 255.255.255.0 gateway 192.168.1.1
Hope this may help someone. Move to Ubuntu, it is super cool
