audio problems

Hi. according to documentation, I thought sound would be working.
This is a Ubuntu installation of 8.10
I have tried the simple things like making sure pcm and master are up. I have added options hda-snd-intel model=acer to /etc/modprobe.d/options, but still no sound.

lspci:

made some change in /etc/default/linux-restricted-modules-common that was Disabled_Modules="ath_hal" this was for wireless, but sound was not working prior to this change.

I have determined sound is working with headphones, and unchecked heaphones box under sound preferences in alsa. The headphones still work. So it is speakers not detected I believe.

Any help would be appreciated.

 

YAY. after many hours, finally found a solution.

I did first rebuild alsa with the latest package from alsa-project: alsa-driver-1.0.19
using ./configure --with-cards=all
make
sudo make install
And edited /etc/modprobe.d/alsa-base to add "options snd-hda-intel model=acer-aspire"

These alone did not work.
Finally:

Code:

wget -c [url]ftp://ftp.suse.com/pub/people/tiwai/misc/hda-verb-0.3.tar.gz[/url]
tar xvzf hda-verb-0.3.tar.gz
cd hda-verb-0.3
sudo apt-get update
sudo apt-get install build-essential
make
sudo ./hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 2

This got sound working, but not after reboot.
cd into hda-verb-0.3 and sudo cp hda-verb to /usr/bin change permissions to 755 /usr/bin/hda-verb

edit /etc/rc.local

Code:

hda-verb /dev/snd/hwC0D0 0x15 SET_EAPD_BTLENABLE 2
exit 0

Dont forget to remove -e from #!/bin/sh -e at the top.

Rebooted and had wonderful sound.
