Revision as of 00:10, 5 September 2006

This category will contain a collection of articles on troubleshooting Linux. It will be highly biased towards SuSE Linux (version 10.1 or later), as that is my primary OS. I am also using a 64-bit (x86_64) kernel, so my articles will also be biased towards these systems.

System information

Sound problems

Note, my sound card specs: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller

  • Un-mute PCM sound
  • Check the following:
% lsmod | grep snd
% cat /etc/modprobe.conf
% vi /etc/modprobe.d/sound

(change "snd-intel8x0" to "snd_intel8x0")

% ./sbin/lspci

(list sound specs / Multimedia audio controller)

% modprobe snd-via82xx

Notes

  • lsmod — program to show the status of modules in the Linux Kernel
  • modprobe — program to add and remove modules from the Linux Kernel
  • netstat — Print network connections, routing tables, interface statistics, masquerade connections, and multicast memberships
  • lspci — list all PCI devices
  • more /usr/share/pci.ids — A list of all known PCI ID's (vendors, devices, classes, and subclasses). Maintained at The Linux PCI ID Repository, use the update-pciids utility to download the most recent version.

This article is curently a "stub". This means it is an incomplete article needing further elaboration.
