linux sound config

some tips to make your sound work on linux


1. to select a default sound output device, edit /etc/asound.conf or ~/.asoundrc to

pcm.!default {
    type hw
    card 0
}

ctl.!default {
    type hw          
    card 0
}

2. if it says permission denied, and only can play sound by root.

 try:

 chmod a+rw /dec/snd/*
