on my lenovo n200 notebook.

specs are: 1.66 GHz, Intel Core 2 Duo T5450, L2 Cache Size 2 MB, fsb 667 MHz
i am single booting to ubuntu.
I have ALC861VD audio chipset.

aplay -l gives

Subdevices: 1/1
Subdevice #0: subdevice #0

and

lspci -v gives

Flags: bus master, fast devsel, latency 0, IRQ 22

Take this advice with a grain of salt, mind you, because I am new as well.

But if the issue is that ALSA does not have an adequate, or any, driver for your sound card, this solution may very well work for you.

From checking the supported devices list of OSS 4.0 (An alternative to ALSA) your device (or at least it's family) is supported.

hdaudio pci8086,2668 Intel High Definition Audio (ICH6)
hdaudio pci8086,27d8 Intel High Definition Audio (ICH7)
hdaudio pci8086,269a Intel High Definition Audio (ESB2)
hdaudio pci8086,284b Intel High Definition Audio (ICH8 )
hdaudio pci8086,293e Intel High Definition Audio (P35)
hdaudio pci8086,293f Intel High Definition Audio (ICH9)

So you may want to do what I did and try switching to OSS, I had to as well because my sound card was not supported well by ALSA (Creative X-Fi).

To implement this switch, use this brilliant How-to by Temüjin, http://ubuntuforums.org/showthread.php?t=780961 Post #2

I hope it helps, and sorry for the long windedness.

Hey my sound's now working all right.
All I had to do was to add this line at the end of this file:
/etc/modprobe.d/alsa-base

Add this line:

options snd-hda-intel model=lenovo

(my notebook is lenovo n200..if yours is some other makers, use:


options snd-hda-intel model=auto

that should probly work)

Then reboot. If you've made everything full in alsamixer (go to terminal and type
alsamixer and make everything full (dont forget to unmute everything using M), when your notebook starts again, you will hear a deafening sound. Go to alsamixer again and adjust the volumes.

You might have a problem saving the alsa-base file after you edit. If it is so (that you dont have the permissions to "write" in that file),
go to terminal and type:

sudo chmod o+w /etc/modprobe.d/alsa-base


Then go and edit the file and save the file(over-write),

Later on ,when the sound has started working, you can go to terminal and type

sudo chmod o-w /etc/modprobe.d/alsa-base
to make the file "un-writable" again..the original setting.

Hope this helps..its worked for many, should work for you too.

i tried this way but noe it says i do not have audio device can you help me?

[satish.bty]

[satish.bty]

dear friend i did as you said .after many tries i got sound.i am the most happy person on earth.thank you very much.

[dbuvens]

super!! adding the line to the file did the trick!! thanks a lot!!

[sarthorks]

It is my pleasure..even i went through a tough time when i had no sound. :)
I just compiled what all i learned after hours on the forum.

[aSmL]

It works for me to.Thanks and best regards :)

[amer-sa]

it doesn't wokr for me
i am a noob in ubuntu and Linux altogether.

[Quiver]

Thanks Sarthorks. I also lost sound. This worked for me too, but I didn't even have to modify the alsa-base file. alsamixer alone did it.

[taco24]

Thank you very much. I finally got the sound working.
I changed the following line in the file /etc/modprobe.d/options

---------------------------------------

# Enable double-buffering so gstreamer et. al. work
options quickcam compatible=2

# Default hostap to managed mode
options hostap_pci iw_mode=2
options hostap_cs iw_mode=2

options snd-hda-intel model=lenovo

---------------------------------
before the model was something else but with model=lenovo it now works.
I also added this line to the file /etc/modprobe.d/alsa-base
as mentioned here in previous posts, but I had to change both files and then it finally worked.
