no sound on ALC889a


for some reason karmic refuses to play sound. I do not get any errors, just no sound. this is a fresh install, and the livecd was the same. sometimes I get sound when I connect my usb speakers, but only from movies.


I tried following this guide without success:http://ubuntuforums.org/showpost.php...15&postcount=6

You can try to configure it as an ALC880 and set-up in modprobe.conf the appropriate option by defining the specific product model instead of letting the system finding out by itself.

As an example I fixed a problem on an HDA Intel using Puppy Linux on an HP laptop.
My problem was sound on headphones but no sound on speakers.

I searched on www.alsa.org site the proper answer with link:

http://git.alsa-project.org/?p=alsa-...6b4df94638eac2

In fact it was due to a wrong definition of number of jacks (stacks in source code). So I modified the modprobe.conf file, with the closest model I cound find on alsa site, at the end of the alsa configuration according to the following:

Quote:
options snd-hda-intel model=laptop

Just to remind you my configuration:
# cat /proc/asound/card0/codec#* | grep Codec
Codec: Analog Devices AD1984A
Codec: LSI ID 1040
Hope this is a hint which can help you.

This is interesting: without change I have sound in flash, in some media players (xine and mplayer) but not others (amarok, dragon) the last group does not even pretend to play. it seems that it is only KDE that can't access the sound card, and thus thoroughly integrated programs are also unable to access it.
