NB200 Sound Solved (One Solution)

I cannot believe that no one has tried this yet... however, here goes. When installing sound on a distro, one is usually told to go with ALSA. However, as many of us know, this creates many problems for us owners of the NB200  netbook. Well, it occurred to me that there is no set rule telling me that I should prefer ALSA over OSS. So, I decided to try that. It turns out, this change produces sound in the speakers, the headphones, AND it has internal microphone support.

So, to install, do as I did: follow the Arch-Wiki on OSS with the following link: http://wiki.archlinux.org/index.php/OSS

The trick here is to disable ALSA before doing any installations by adding !soundcore and !alsa to your modules in rc.conf and making sure to restart before proceeding with the installation of OSS.

After everything is up and running, change your mixer setings using

ossxmix

and test your speakers using

ossplay /usr/share/sounds/alsa/Front_Center.wav

.

If everything works, enable your microphone as well in the ossxmix by going to the box labeled "int-mic" in the second section of the oss mixer, and change the input mode to "input".

You can test your microphone as follows. Go to your home directory by issuing

cd ~/

Now, issue the following command:

ossrecord -l test.wav

This will create a file test.wav in your ~/ directory, while the option -l will produce a meter so that you can see your microphone activity. To stop the recording, issue Control+C.

That's it! Problem solved! Enjoy your new speakers! big_smile

I got the speakers working using OSS. but the mic isn't working. It isn't detected on kde's systemsettings > Multimedia (blank) but ossinfo shows otherwise
