Sound Problem

I am using Ubuntu 10.04 LTS.Suddenly the login sound stopped working.Also the sound theme does not work(sound effects).But all the other sounds such as audio preview,audio,game sounds,youtube sounds etc.work.I hear the drum sound when I log-off.
Skype test call works but there is no sound while starting up skype.I googled but could not find any solution to my problem.Thanks in advance.

 

Try this

sudo lsof | grep pcm

sudo /etc/init.d/alsa-utils restart

 

Tried but it did not bring the system sounds back.

 

sudo apt-get --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2

 

Sorry for asking but I really do not know the commands.I only copy and paste them in the terminal.Is there any chance of losing the sound which I have now by using this command ''sudo apt-get --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2''

If there is any chance of losing the sound I have I can stay without the login or system sounds.

 

Cet,

You are absolutely correct in being cautious, this is from Ubuntu manpage and it removes and reinistalls the sound module. I suggest you do your own study on this before proceeding further.

This is the output of the first commands.Maybe you can understand what the problem is:
ceylan@ceylan-desktop:~$ sudo lsof | grep pcm
[sudo] password for ceylan:

I checked and the alsa-utils is installed.


I found a similar problem here.http://forums.opensuse.org/english/...all-boot-login/435715-login-other-sounds.html

 

have you check this

by right clicking on sound icon and sound preferences

also try diffrent theme sound see what outcome is

 

Sound problem is the only reason why I don't use Linux.
Tried many distros and same thing with all of them.
Problem is, sound is working fine but only in stereo mode, can't make it to work in 5.1 mode.
Only left and right speaker are working, the rest of them are dead.

 

Ubuntu forum has an excellent guide on how to make 5.1 work on it, have set that up for my friend's ASUS Xonar card and it works fine. Linux is the only distro that will still run my ancient but superb Yamaha and Turtle Beach cards.

 

Can you post the link for it please ?

 

gksu gedit /etc/pulse/daemon.conf

This should open up the configuration file in gedit. Once open, scroll down to find the line ; default-sample-channels = 2. Remove the semicolon at the start of the line and change the line according to your surround sound configuration:

For 5.0 channel sound: default-sample-channels = 5

Linuxforall thanks, I tried every command and the link you have written.But all I get is command not found.
I installed gnome alsa mixer too.
Not having system sounds is not important because every other sound works.But it makes me frustrated not to be able to solve the computer problem.
When I look at the installed sound programs I see pulse audio too.

 

Many thanks Sir

 

Welcome, please post feedback when you can.

 

cet, have a look here as regards login sounds.. http://www.howtogeek.com/howto/22428/disable-login-sounds-in-ubuntu/

You may want to install padevchooser - check the Playback tab...

 

Sure will, don't know when though, but very soon, need to install it first and I can't test it in VM because different sound card is recognized in VM.

You reckon I can test this with LiveCD ?
Guide says I should reboot after the change in daemon.conf , and I see that as a problem for a LiveCD
Is there a way to restart sound system without rebooting , or something like that ?

 

Live CD no but live USB definitely.

 

linuxforall, hi,

Just a question can't one simply do :-

pulseaudio --kill
pulseaudio --start

or would you consider that verging on the dangerous ?

Btw. for 5.1 default-sample-channels=6

Nice speaker tests without looping and using default wav files..

speaker-test -Dplug:surround51 -c6 -l1 -twav (for testing 5.1)
speaker-test -Dplug:surround40 -c4 -l1 -twav (for testing 4 speaker sound)
speaker-test -Dplug:front -c2 -l1 -twav (for testing stereo sound - one stereo jack)

 

Ocky I guess that can be done as there is no kernel level drivers to be loaded here, worth a try.

 

Tried the solution from the guide in VM with Ubuntu , although the name for the card found is different than in the "real" installation , problems are identical.
Anyway, it didn't solved the problem, I can only have stereo mode, not 5.1
I think that the problem is deeper here, maybe the config for the sound card or something.
btw what is Stereo Duplex ?
And what actually do I have to choose from all those mods to have 5.1 sound ?
Tried them all of course, still "Test Sound" is showing just two speakers.

speaker-test -Dplug:front -c2 -l1 -twav is working. I can hear the sound from left and right speaker.
speaker-test -Dplug:surround51 -c6 -l1 -twav (5.1 test) is not working and I can't hear anything.

In Windows it's very easy, there is "Stereo" mode and "5.1" mode , and that's it.
Works perfect.

Can't believe how something simple is so complicating in Linux world, ALSA, PulseAudio, config files, muted, unmuted, this and that ...

 

The solution was simple,I installed it and the volume was at 1%, I made it 100% now I hear the skype login event sound and I also hear the window and button sounds.But the normal sound icon on my pc was at 70%.So I guess they are different?
BUT still no start-up sound.Lol.


/usr/bin/canberra-gtk-play --id=”desktop-login” --description=”GNOME Login” is this the right startup command for the gnome login sound?

 

I have this:
/usr/bin/canberra-gtk-play -V -25.0 --id="desktop-login" --description="GNOME Login"
where "Note,the -V parameter describes the volume in decibel (neg logarithm), so 0 corresponds to full volume and -50 can barely be heard."
