View Full Version : [ubuntu] Minor Sound Issues after upgrade from 9.04 to 9.10

[Repost] - felt like this might be a more appropriate place to post my concern.
Hello,
I just joined the Ubuntu community today - but I would say I am an intermediate Linux user. I have been exploring Ubuntu since 8.04.
I upgraded my Dell Laptop from 9.04 to 9.10 and it works almost perfectly except for some sound issues. The sound technically works, but the volume is excessively loud and adjusting the volume control does not make much of a difference. If I max out the volume - very loud, if I minimize the volume - still very loud but sound quality is heavily degraded. This issue seems to be global, since it does not matter whether I am watching youtube or playing music in Rhythmbox.
So the questions I have are these:
1) Has anyone experienced something like this before?
2) How can I determine what sound driver is in use and whether it is working properly?
3) Are there other options I can take? Different sound drivers I can try?
4) How can I uninstall/reinstall sound drivers?
Thank you for your time.

check to see which sound you have alsa or pulse
Ubuntu 9.10 comes with pulse audio some people revert back to alsa there are links to this in the forum however from a clean install i installed pavucontrol in synaptic pkg manager this once installed check to see if the pavdevchooser and volumemeter has installed if not install them and check to see if there are any plugins required depending on software you have installed .goto apps sounds and video click on the pulse audio device chooser the jack should appear in the top right panel click on it and select configure local sound server click your options / also check this goto system admin users and groups click on the keys/click to make changes /enter your password click on manage groups /go down the list and find pulse entries click on each one in turn and anclick properties /check the boxes
root and user that will be your log in name /once done you may have can see how the system is set up from that devchooser jack . the volume meter etc will show you how many channels are open also you may need to set sound option in each program

I believe that I am using ALSA - but how do I confirm this? I figured this because I was messing with the Alsamixer and noticed that when I increase the master volume from the applet on the desktop bar, the PCM and LFE channels increased VERY rapidly (they maxed out almost immediately) and the 'Master' channel increased much more slowly.
Is it possible to correct this behavior and make the volume increase more steadily?
How can I "convert" to Pulse from ALSA?
Also, I do not know what you mean by 'pavdevchooser' and 'volumemeter'. A search in Synaptic yielded no results.
Thank you for your time.

Hi been to Bed
if you go to system admin users and groups click the box click to make changes
enter your password and click on manage groups click do you see any entries for pulse
if there click each one in turn and then click on properties the boxes user and root need to be checked
if pulse is not there then pulse may not be installed
can you try this from the terminal and post the results
$ aplay -l
$ gedit /etc/pulse/daemon.conf
if you go to synaptic type in the seach area type in " pulse"
in the listings you should pulse bits
are any of the pulse boxes green
look down the list
can you see
padevchooser
pavumeter
pavucontrol
or anything with pulse
if nothing in pulse you can try this
right click the loudspeaker / top right panel
to open then control
if its alsa then the alsa switches with be visible
are they single or double
if there double there should be a chain showing at the bottom
you can click on the chain to break it this gives you seperate control over the channels
also hovering over the switches with the mouse a description should show what channel is which
if the switches are single then you may have to play around with the sound prefs and swiches to get the desired result
also found this thread worth looking into

I attached a script of the output of the commands:
aplay -l
cat /etc/pulse/daemon.conf
And I was able to find the 'padevchooser' and 'pavumeter' and 'pavucontrol' packages and installed them.
Thanks for your time.

Also, I forgot to mention that I did see pulse entries in the users and groups properties and I made sure I checked the boxes for both my username and root.
alexfish
November 16th, 2009, 07:57 PM
ok
do you now see the pulse audio device chooser in the apps sounds & video
also go to system preferences do you see pulse audio preferences
if so click the audio device chooser in the apps
the jack should show up in the top right panel
click on it and you will see a dropdown menu list
let me know if this there

Yes, the PulseAudio applet appeared in the top right panel. I click it and there is a dropdown menu.

I just checked the boxes for both my username and root for the pulse entries in the users and groups properties. It was not checked.
I rebooted but pulse is not appearing yet in Application-> Sound & Video.
Also here is what i get when I issue
aplay -l
feddozz@feddozz-laptop:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****

the menu list should be something like this
default server
default sink
default sauce
-----------------
manager
volume control
volume meter play back
volume meter recording
configure local sound server
preferences
-----------------
quit
Click on the manager
look at the pages
server info
devices
clients
modules
sample cachet
under the server info
what is the default sink
what is the default sources
under devices do the sinks and sources match server info and does the description match your device from the aplay-l command that you did in console
in the clients you prob see
cosolekit
gnome volume control media keys
esound client(unix socket client)
gnome volume control applet
esound client
esound client
esound cliend
libcanbera
pulse audio manager
in the sample cachet what does the playback on show
Next rightclick the loudspeaker and open up the sound preferences
in the output you will see the sliders that relate to the output you pick
when done let me know /
check that the sound is not muted
click on the hardware
you should see your card and a drop down box with a list of options
for testing mine i picked a playback with 5.1 sound
you may still have no sound at this stage

Did you try doing this yet? This should install the required packages and allow you to see the PulseAudio applications under 'sound and video.'

Ok I installed pavu packages and now I have got pulse in Application->Sound&Vid
I opened volume control while playing a youtube video, on the tab playback I can see the volume bar moving. On the tab Output devices says i don't have any hardware output devices available

ok now post #11 is clear
in server info
default sink=auto_null
default Source= auto_null.monitor
In devices sink and source match those in server info but no match with aplay-l list
Sample cache playback=auto_null
in sound preference output I see only one device called Dummy output
Hope I collected all the info
thanks!

I am seeing from your list something which seems odd ie modem device
check your hard ware with a device manager
you need to right click the loudspeaker icon to get the sound prefs
ps what mother board is it
do you have add on cards if your using on board sound make sure its available from the bios
and that the sound system is connected to the correct jacks
was it a clean install of ubuntu or an upgrade
added / 18 November
your software modem is found with the aplay -l in the console
try this link for cure

some people are experiencing problems after upgrade
if ubuntu is the only os on your toshiba it may be worthwhile doing a clean install using whole hard drive if you got os or home directory you want to keep then follow another thread / there are threads in the forum. back soon

Isn't easier to just copy the home directory onto another media such as an external HDD, thumb drive, or CD/DVD?

hi maximus
how is pulse going
yes some times easier for the home directory
billiusmaximus
November 16th, 2009, 11:35 PM
@alexfish:
Default Sink: alsa_output.pci-0000_00_1b.0.analog-stereo
Default Source: alsa_input.pci-0000_00_1b.0.analog-stereo
And yes, the devices match the server info. However, under devices, there is a second source:
alsa_output.pci0000_00_1b.0.analog-stereo.monitor
Not sure what that means.
Under clients, I see everything in your list except 'libcanbera' and 'consolekit.' So I searched for consolekit in Synaptic and it is already installed.
Thanks,
Billius

they seem fine
play some music with your player select volume meter playback from the jack
any results showing
next step is to try
select system prefs pulse audio prefs
these are the boxes i checked
network access / make discoverable pulse audio sound devs available locally
network server / enably network acess to local sound devices
simultaneous output / add virtual output device for for simultaneous output on all local sound cards
maybe try a reboot and test again

this is another screen shot with the volume control sliders unlocked
they should move independant of each other

Unfortunately, there has been no change to the behavior of my volume control. I am thinking perhaps I might uninstall all the pulse stuff and try reinstalling.
I am also considering doing a fresh installation of 9.10 to see if that resolves the issue. However, I am dual booting XP/Ubuntu and I am not sure if I know how to repave Ubuntu and leave XP untouched. I am sure it's possible though.
I provided 4 screenshots of alsamixer. The first shows everything muted, and from there I incremented the master volume slightly, as you can see on the right side of my screen. Then notice how the alsamixer behaves on the left.
Thanks,
Billius

your top slider seem to be set to 0
but showing 100%
try moving the slider to full ( move it to the right )

try selecting pulse audio volume control from apps
here is a screen shot
the window on the left is it
click on the play back
goto apps
select totem movie player
goto edit preferences click on the audio
and select which matches your speaker set up
play a tune does it look like this attached screenshot

is your system amd64 or 32bit / looking at other threads 64 bit seem to have bigger headaches
