Public bug reported: I got ubuntu 9.10 installed on my laptop. Whenever a headphone plug in to the jack, there's no sounds from both built in speaker and headphone. I follow the steps below and it aggravate the matter that no sounds at all even the headphone unplugged. I'm totally new to linux system. I'm seeking your kind help.
[email protected] [HOW TO] Enable Sound in LG LW65/LW75 As detainer of this laptop model, you already should know, this LG laptop model always had some issues to enable speakers over linux. So, and after try many diferent ways, and searching in to many forums, this included, i found a working solution to the problem. I tried this on a ubuntu clean instalation, but it should work in every linux instalations. First of all you should download some alsa archives, the essential ones, are alsa-driver and alsa-lib: Code: wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.21.tar.bz2 ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.21a.tar.bz2 Then, you need some packages from ubuntu repositories, i needed this ones (libncurses5 libncurses5-dev xmlto) but you could need some more, use google and some good sense to find them: Code: sudo apt-get install libncurses5 libncurses5-dev xmlto patch Now, we need to unpack the tarballs dowloaded and install it: Code: tar -xf alsa-driver*.tar.bz2 && cd alsa-driver*/ && ./configure && make && sudo make install && cd .. && rm -r alsa-driver*/ tar -xf alsa-lib*.tar.bz2 && cd alsa-lib*/ && ./configure && make && sudo make install && cd .. && rm -r alsa-lib*/ You should get no errors. Now we need to use alsaconf, alsaconf doesn't come anymore with ubuntu, so we need to compile it. To do that, you need to compile alsa-utils as before: Code: wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.21.tar.bz2 tar -xf alsa-utils*.tar.bz2 && cd alsa-utils*/ && ./configure && make && sudo make install && cd .. && rm -r alsa-utils*/ Now just run alsaconf: Code: sudo alsaconf This normally is a normal next, next, next instalation, but you could always change some parameters, if you know what you're doing. Now, you should add your model to alsa configuration file, in lg lw series, the model is minimal, because they use c-media cards, instead realtek: Code: sudo echo -e "\noptions snd-hda-intel model=minimal" >> /etc/modprobe.d /alsa-base.conf After configuring all, and running alsaconf, you should run alsamixer, and place all volumes unmute, shourtcut is 'm', after change to desired channel. Code: alsamixer After that, test speakers, if everything is ok, you should hear now your speakers again like in windows old times (Ctrl+C to stop): Code: speaker-test -c2 If it doesn't work, reboot your system, and repeat the last 2 steps. Some issues more, use this post to get your answers. Tested in Hardy, Intrepid (with some issues compiling alsaconf), Jaunty and Karmic. Last edited by bluryfusion; 15 Minutes Ago at 11:05 PM..
