I have Sound, Sorta

~zoey~ · 01-14-2009, 10:12 AM

I have installed ubuntu 8.10 on a Sata drive using an Intel DG33TL board with onboard sound. The sound has been faint or non-existent since installation. In sound preferences everything yields a tone except sound capture. I have the volume set high in master volume control, gnome alsa mixer and pulse audio. I have very faint login sounds and Rhythm Box will play softly with volume on high. I attempted a fix for pulse audio as posted in the ubuntu forum;http://ubuntuforums.org/showthread.p...ighlight=sound but bash didn't like the very first command. My onboard sound is recognized;

sudo nano /etc/group
Find pulse-rt and add your name to the end of the list.
Quit then retry

That gives me this;

root:x:0:
daemon:x:1:
bin:x:2:
sys:x:3:
adm:x:4:margo
tty:x:5:
disk:x:6:
lp:x:7:
mail:x:8:
news:x:9:
uucp:x:10:
man:x:12:
proxy:x:13:
kmem:x:15:
dialout:x:20:margo
fax:x:21:
voice:x:22:
cdrom:x:24:margo
floppy:x:25:

with the cursor blinking on the r of root and I don't know how to proceed from there.
I did check the permissions in user and groups and pulse, pulse access & pulse -rt are all listed.

Thanks, zoey

Before we go any further, did you do this bit:

Code:

Part C: Intrepid Ibex (8.10)
Follow the steps in this section only if you are running the Intrepid Ibex release.
Disclaimer: Currently there are no updated packages for Intrepid in my PPA (except for an updated nspluginwrapper package for i386 users). I have decided to keep this step in the guide in case I upload any important updates that will not make it into the official repositories. I will never upload any "risky" packages (i.e. highly untested backports), only upgrades that seem compelling and relatively stable.

1. Edit /etc/apt/sources.list:
Code:
$ gksudo gedit /etc/apt/sources.list
If they don't already exist, add the following lines to the end of this file and save:
Code:
# PulseAudio Fixes - http://ubuntuforums.org/showthread.php?t=789578
deb http://ppa.launchpad.net/psyke83/ubuntu intrepid main
deb-src http://ppa.launchpad.net/psyke83/ubuntu intrepid main
2. Update your repositories and upgrade packages:
Code:
$ sudo apt-get update && sudo apt-get dist-upgrade
Note: You may be warned that some packages cannot be authenticated - that's normal. Simply press "y" to confirm installation of unsigned packages.

3. Ensure that your sound card's PCM mixer is not muted or set to 0% volume (this appears to be a bug in Intrepid):

Code:
$ alsamixer -Dhw
Note: When the PulseAudio ALSA plugins are active, you must explicitly specify your hardware device in alsamixer (marked in blue above), otherwise it will open the PulseAudio mixer.

4. Log out & back in for changes to take effect!

Yes I did that. I have tried various "fixes" from the ubuntu forums, one of which lost all sound until after a restart when I was right back where I started.

Thanks, zoey
