My laptop's speaker became muted that day after I plugged in my
earphone. Since then it doesn't play any sound, no matter how I tried
to plug and unplug the earphone, reboot or change the BIOS settings
(expecting a more through hardware probing during boot...) I even
tried the latest kernel (22.214.171.124-26.fc9). My alsa-lib is 1.0.15
Please the almighty tell me how to fix this? I'm not sure if it is a
hardware issue. Thanks!
