Re: No sound! Ubuntu 8.10 and SI7012

[Brian Harrington <harrington01@xxxxxxxxx>]

Hi Bill:

This is a friend's laptop.
She dorked up XP, and I installed Ubuntu over the top of it.
So now I feel responsible for getting her a working system.

Thanks for your help!

anna@anna-laptop:~$ aplay -l

anna@anna-laptop:~$ aplay test.mp3

...but no sound
The results of lspci:

The modprobe.d directory has an alsa-base file:

Now, exactly what kind of help? You tell us nothing about your
 system except
that is some unit purchased in Hong Kong and it used to run windows. I could
tell you to throw it away, but you would probably not find that helpful.
(NEC seems to have abandoned it already-- it is 4 years old)

If however you were to tell us what kind of soundcard it had-- run
lspci 
For example on my system reports for the audio
00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM
(ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 02)

we might have a chance of figuring out what you have and giving you advice.


Also show us what is in 
/etc/modprode.conf or in one of the  /etc/modprobe.d/* files which might have
something to do with audio.

Also if you run
alsamixer
in a terminal window, do you get anything? Are the sliders slid up if there is
something.

Finally, you could buy a usb sound card and use that instead. There are some
pretty cheap ones
 and most tend to work with linux usb sound driver.
