i am a Linux newbie and have very little experience in it. I recently installed Ubuntu 9.04 (clean installation) and performed all the routine updates...
Everything seems fine except that no matter what i tried, sound did not work..... i tried update manager and updated latest ALSA (as recommended in some site on web) I tried reconfiguring PulseAudio....
Even followed a PulseAudio Applet tutorials.... yet i did not get sound working....



on executing lspci |grep Audio
I get the following...

00:14.2 Audio device: ATI Technologies Inc IXP SB4x0 High Definition Audio Controller (rev 01)


what should i choose as my sound preference?


In Pulse mixer, the bar indicates that a sound is being played.... except i dont hear anything....

alsamixer -Dhw

shows the volume of all at maximum....

i made sure nothing is mute....

the sound works absolutely fine on Windows... i want to make it work in Ubuntu.... please help anyone!!

my friend has a hp and he had absolutely no problem since the first installation .....

Someone please guide me to get the sound working..... Please!!

Have you tried opening a terminal window and typed sudo alsaconf and run through the setup?

No capitals...

It is not considered wise, useful, nor polite to post using capital letters as you have done. You will obtain less attention, less consideration, and less help than you otherwise might.

I would recommend you edit to a more accepted type face.

@ mrrangerman: i have tried what you suggested... but it said...

sudo: alsaconf: command not found


what should i try next?? thanks for the post..

if i try the following command... it gives the following output..

what should i do next? thanks in advance..

and it is not a permissions thing either...

i tried

sudo -i
alsaconf

the bash gave an error saying command not found....

Apparently alsaconf has been removed; so, it is not a surprise that you could not find it. Anyway, beyond that bit of trivia, I'm afraid I've got no useful suggestion for you.

Did some further browsing, and found, on the Debian wiki, this tidbit: "try to configure alsa by running the command 'alsactl init' as root." There's further discussion about this on the Debian user forum.

@mark_alfred : thanks for the heads up.... i tried

alsactl init


Unknown hardware: "HDA-Intel" "Realtek ALC260" "HDA:10ec0260,103c0000,00100400 HDA:14f12bfa,103c30ba,00090000" "" ""
Hardware is initialized using a guess method

what should i do now? Anyone?? it would be really nice if someone can point me out in the right direction.... what should be done next....

also apparently,
in the volume control tab of pulseAudio,
it is displaying Null output instead of any device....

what next can i try?

Module...

Two thoughts...

Just to check,try to find out which kernel module 9.04 is loading by using the command "lsmod". See "man lsmod"


This seems to be the best guess by 9.04 for finding the module to use, but there is no guarantee that it has guessed correctly.

Try the command "lshw" to see if you can identify the chip that way, and see if it is found as a Realtek ALC 260. I believe the kernel module ALC260 uses is snd_hda_intel.

Have you looked at, or looked for, the documentation of your motherboard or sound card for more information? Google naturally helps.

This line of approach assumes that the sound module being loaded may not be correct and that the information you could gather would allow you find and have the system load the right module.

A bit more...

Try the command "cat/proc/asound/card0/codec#* | grep Codec" or "aplay -l" according to this thread.

http://ubuntuforums.org/showthread.php?t=616845

The output should give the precise chip or card.

You may read on to see if the thread is a solution to your sound problem.
