True solution - Making sound work on Lenovo Y410 with Ubuntu 8.04 LTS

Well i had recently struggled with making sound (audio from speakers and headphones) and mic (external and internal) work with Ubuntu.

Here are my observations, there are some sites that indicate that alsa has to be rebuilt .. here is the link which will help you start
1. http://jaux.net/2008/04/27/solution-to-lenovo-y410-sound-problem-ubuntu-804/ run the shell file thats there. (

chmod +x y410_sound-20080427.sh
sudo ./y410_sound-20080427.sh

)

2. Now that solves some problems, with people indicating adding this to the end of alsa-base file.
"options snd-hda-intel index=0 model=fujitsu"

And most people agree that this is the solution, though headphones wont work and internal mic wont work ..

3. Making internal mic and headphones work ! Ok here is the issue, adding fujitsu solves some issues but here is my solution thats probably not right but the best.
a) dont have any options (the line which indicates fujitsu) or anything ..
b) restart alsa, or restart system.
c) Now for every restart, you need to suspend and come back from suspend.
d) this will make headphones work, just that headphones wont automatically disable speakers .. for that go
to sound settings or alsamixer from shell, and mute "Front speakers" (no use of reducing to lowest volume .. mute is necessary).
e) similary select Front mic (internal mic) everywhere that asks for the source of input.

I am now in vista, so i am unable to post ubuntu screen shots, but i will certainly be looking forward to posting the screenshots.


But yes, sound does work well, with certain tweaks, and i dont like the fujitsu option, since
though that start the sound on its own .. it fully kills headphones.
