Relaltek声卡在UBUNTU下没有声音的解决方法

Thecomputer has an HDA Intel chip (Realtek ALC887) and I couldn't openalsamixer (this error was displayed: "load hw:0 error: Invalidargument"), although the sound seemed to be working in variousapplications (no error there) except I couldn't hear anything. 

Thefix: 

Edit /etc/modprobe.d/alsa-base.conf: 
sudogedit /etc/modprobe.d/alsa-base.conf 
And add the followingline: 

optionssnd-hda-intel model=generic

Save,reboot (a logout might be enough too) and the sound should work. Ifthis generic fix doesn't work for you, see THIS(http://ubuntuforums.org/showthread.php?t=314383) post.

无需重启，运行下面命令即可：

sudoalsa force-reload
