under "How do I get sound output working?" in the following sentence: "Second, users who should have access to the audio devices need to be added to the appropriate group with the command chmod -g audio [username]." it should be "usermod" instead of "chmod". Reproducible: Always Steps to Reproduce: 1. 2. 3.
You're right, but '-g' sets the initial group name. Here we just want to add a supplementary group. If I had no better answer in a few hours, I'll replace that chmod by "usermod -G `groups [username] | sed 's/ /,/g'`,audio [username]"
Fixed + removed bad link to http://lppcfom.sourceforge.net/, thank you.
