The machine has decent specs like Pentium dual core. 1GB RAM and 160GB\u00a0 hdd.\u00a0 It came preloaded with windows vista. As I use Linux , I partitioned the hard disk and installed\u00a0 ubuntu8.04.\u00a0 Unfortunately\u00a0 sound is not working under Ubuntu.<\/p>\n
I\u00a0 looked at the\u00a0 lspci output and found out\u00a0\u00a0 the following.<\/p>\n

I installed the following packages.<\/p>\n c) Next\u00a0 you have to prevent the default Alsa\u00a0 modules from loading up. This\u00a0 can be done via a file named<\/p>\n \/etc\/modprobe.d\/blacklist<\/p>\n Execute the following on command line.<\/p>\n Please take a look at \/lib\/linux-sound-base\/noALSA.modprobe.conf. It contains the modules to be blacklisted for ALSA.<\/p>\n d) I added the following additional lines to \/etc\/modeprobe.d\/blacklist<\/p>\n Now reconfigure the linux sound base.<\/p>\n You will be prompted to select the sound system.
