Sound Heard in external headphones but not in internal speakers of laptop

@skm3nt · 08-20-2010, 06:56 AM

Hello everyone, I am new to fedora 13.
My problem is that I can not hear any sound from my laptop's internal speakers (that works f9 in windows--so no h/w probs!) but when I connect external headphones, everything is heard!

I have tried several commands from various internet sources since past one week. I would like to list a few of them:

580 rpm -ivh http://download1.rpmfusion.org/free/...ble.noarch.rpm

581 yum install vlc

583 yum install pavucontrol

595 lspci | grep Audio

596 cat /proc/asound/card0/codec#* | grep Codec

597 yum --enablerepo=rawhide update alsa*

598 yum update alsa*

599 yum --enablerepo=rawhide update alsa*

662 chmod a+rw /dev/dsp /dev/mixer /dev/sequencer /dev/midi

I don't understand many of the commands that I have run, but that has somehow helped me to run media files and hear sound on HEADPHONES....

I have checked and think nothing is muted (using instructions from forums....)

I will be very thankful if someone can help me solve this problem.....

if it were me, i'd erase pulseaudio, as that always caused me weird problems in fedora. Try

Code:

su -c "yum erase pulseaudio"

Also I assume you have tried all the mixer option? Try running

Code:

aumix

or

Code:

amixer

or

Code:

kmix

or whatever relevant is installed, and fiddle with all the dials. you may have speakers on mute or something.

@skm3nt · 08-20-2010, 11:11 PM

I got a suggestion:

Have you tried to go to System -> Preferences -> Sound -> Output
Here you should see a menu named 'Connector:' Where you can choose your output, choose Analog Speakers for the sound to be played on your laptops internel speakers...

and that solved my problem!!

I would like to ask you whether pulse audio is a software(application) or driver kind of thing? Do vlc, rythembox music player, movie player and pulse audio are same category things and would be ok if I keep one of them?

I have one more problem as well if you would like to see if you could help me:

And thank you for showing interest in my problem :-)

Pulseaudio is a sound server - it kind of sits between the sound software and the hardware, the idea being that you can have multiple sound sources (such as vlc, rhythmbox etc) playing at the same time, and control the volume of them all individually. Rather than the old way, which would be to mingle all the sound sources, and have one "master" control to control the volume out. The only GUI you will see for puleaudio would be a mixer settings GUI.

It's been notoriously troublesome though, and many many people think it just adds further complexity and problems. It's very common for people to remove it altogether. Linux audio is a nightmare in my opinion; it's too complicated by far.

Withg regard to your second problem. Try the following commands to give you some more information -

Code:

service -status-all

chkconfig -list

The following command will find the httpd config file, which you should review for any obvious errors (for example lack of a valid IP address and name for your webserver) -

Code:

rpm -qc httpd

Also make sure you have the following packages installed -

Code:

yum install httpd httpd-manual httpd-devel

EDIT - I notice that httpd is in /usr/sbin, so maybe it is only controllable as root? (the sbin dir is for root-only programs, it is not in a normal users $PATH). Try the following, as root user -

Code:

chkconfig httpd on

service httpd start

The service needs a valid IP address and name or will fail, so make sure you add a ServerName entry to the configuration file as well. Then restart the service.

@skm3nt · 08-22-2010, 05:47 AM

service -status-all --> unrecognized service
chkconfig -list --> list is unrecognized option

The packages you mentioned are already installed. I don't understand the contents of the conf file, I am attaching it here...

Status is still the same-->httpd dead but subsys locked

spoovy · 08-23-2010, 03:41 AM

Are you running those first commands as root? Try with a double hyphen ie

Code:

chkconfig --list

and check their man pages.

Have you checked that you have a valid IP address and server name?

@skm3nt · 08-24-2010, 12:58 AM

Where to check for a valid IP address and server name?

spoovy · 08-25-2010, 03:14 AM

Blimey mate i'm trying to help out here, but you gotta meet me halfway! Have you read up on how to use Apache?

@skm3nt · 08-28-2010, 07:26 PM

i'll do so asap n get back
