Also you may be having some other audio devices and may need to select the correct one.

Hi,

You may just need to set-up appropriate option in modprobe.conf for your sound card, I had an issue with PUPPY and HDA Intel sound card on an HP Laptop.

My initial problem was sound on headphone but no sound on speakers

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

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

and tried to find a card reference sufficiently close to mine and set-up options. snd-hda-intel configurations start at line 746

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
I hope this can help ypu

Talking Solution for No Sound when Upgrading from Ubuntu 9.04 to 9.10

SOLUTION!!!
Ok figured out what went wrong with the Sound when I Upgraded from Ubuntu 9.04 to 9.10. I remember while installing the upgrade, the prompt asked me if I wanted to keep the old version of the menu.lst. I replied no, and that was the problem. Even though the new kernel was built, the grub menu.lst did not pick it up, and was still using the older kernel.

So here's the SOLUTION...:
-->Goto Synaptic Package Manager

-->search for grub-pc

-->Install it

-->When the system reboots, you'll see the grub menu. If it boots up ok, and you can verify sound is occuring, then reboot and pull up a terminal and type the following...:

upgrade-from-grub-legacy

-->(press ok to the first prompt, then MAKE SURE TO PRESS THE SPACE BAR when the [ ] /dev/sda prompt appears so that an * populates the brackets[*]. Then tab down and press ok.)

--> You should be good to go.
