sudo killall pulseaudio

Hi everyone! Recently, I've upgraded Ubuntu from 10.04 to 12.10, and this little audio problem keep bugging me since day one I've upgraded it. I've followed all the tips from this blog to solve my audio problem. I think I've solved it. But, everytime start my machine, I've to insert "killall pulseaudio" to reset my Dummy Output to normal ones. Tips anyone to overcome this pesky bug? Thanks!

If running killall pulseaudio at startup works, consider just putting that in startup scripts?

Two ways to do so:

1. Go to Startup Applications. Click add.
2. Add it to the end of ~/.bash_login

Edit: I'm stupid, this is a sudo command, of course it won't work this easily.

How much do you like external volume controls? You might be able to just uninstall pulseaudio completely.

sudo apt-get autoremove pulseaudio and then reboot.

Edit: I really should stop giving advice after not sleeping. Getting rid of pulseaudio won't work.

You *can* give your local user the ability to run killall on pulseaudio without sudo.

See here: https://help.ubuntu.com/community/Sudoers

And then put it startups.

have you read through these solutions?

First, let me decribe what the problem was:
1) no audio card was detected at all
=> cat /proc/asound/cards returned an empty content
=> cat /proc/asound/devices did not include any audio devices
=> 'Hardware' tab in sound preferences was empty
2) the audio tray indicated a "dummy output"


SOLUTION
========

For those who do not have a fresh Karmic install (in other words those who have upgraded their Jaunty install), you should update your Grub BEFORE applying the 2 steps described hereunder:

sudo update-grub



Step1: make the sound card being recognized

=> Purge alsa-base and pulseaudio, eg:

sudo apt-get remove --purge alsa-base
sudo apt-get remove --purge pulseaudio
sudo apt-get install alsa-base
sudo apt-get install pulseaudio
sudo alsa force-reload


Now, reboot, you shoud now SEE (but maybe not yet hear) your soundcard.
Give a try to:
cat /proc/asound/cards
and see if any card is listed...


Step2 : If the sound is crapy, you MAY have to edit the alsa config file:

sudo gedit /etc/modprobe.d/alsa-base.conf

a) comment (#) the following line:
# options snd-hda-intel power_save=10 power_save_controller=N

b) Add a new line
options snd-hda-intel probe_mask=1 model=hp

Replace "hp" with appropriate computer model. See here

Good luck !

Bernard.

I believe I've followed all the tips above, & yet, I still have to force reload my sound card at each machine starts! 1 thing for sure after scouring the threads; my Acer TravelMate 6292 has a modem, so that could be THE problem. Question, how I tackle the modem problem. Some said in the thread, the modem software should be disabled, so, how do I disable it?

Ok, I think this is the time where I cry for help for breaking my sound system ... This is the output of running the script from ALSA

I believe I've solved my problem. Thanks people, thanks Google!

I did the following as stated above,

sudo apt-get remove --purge alsa-base
sudo apt-get remove --purge pulseaudio
sudo apt-get install alsa-base
sudo apt-get install pulseaudio
sudo alsa force-reload

I added the following,

sudo apt-get update

I restarted twice, then it worked. This problem is the same since Ubuntu 10+, now I am on 12.04LTS yet we still have this same problem. Any chance this can be fixed permanently?
