no sound

[geezer]

Need help in understanding how to fix my new 9.10 installation.

The sound card does not respond when I test using the system settings: "system Settings->Multimedia"

The sound card is listed: HDA Intel (Stac92xx Analog)

along with Pulse Audio and the digital equivalent of HDA Intel

The analog used to work under 9.04 and previous, but when I click test, no sound.

If I click Pulseaudio, a window pops up and says the pulseaudio does not work and falling back to the HDA Intel (Stac92xx Analog).

Any ideas on how to get sound working again under 9.10?

Re: no sound

Click on the KMix icon, then the Mixer button. See if there is a channel for PCM (it has a blue squiggly line at the top). If it's not there, you may have to add it using the "configure channels" setting. Make sure it is not muted, and volume is set all the way up.
Also, please post the output of the following:

cat /proc/asound/modules
ps aux | grep pulseaudio

no sound on anything--SOLVED--

I made Pulse audio on the main one, and now I have sound

I have the same problem with the same card, this is what I got

richard@Knights-1:~$ cat /proc/asound/modules
0 snd_hda_intel
1 snd_usb_audio
richard@Knights-1:~$ ps aux | grep pulseaudio
richard 2668 0.0 0.2 204324 4596 ? Ssl 06:06 0:00 /usr/bin/pulseaudio --start --log-target=syslog

Re: no sound

I had the same problem.

After moving HDA Intel to the top (Higher priority than PulseAudio) the sound is OK

OK, two thing to try here:
1. Do as ErkiSvensk suggests.
2. In pavucontrol, open the Configuration tab, make sure that the sound card you want to use is set to "Analog Stereo Duplex" or whatever output mode you want, and the card you don't want to use is set to "off". Open the Output Devices tab and make sure the entry for your card is set to "Analog Output", or whatever mode you are using. Then start your player. Check the Playback" tab, there should be an entry for your player (It will likely say, "ALSA Plugin -something") Make sure this is not muted, and has some volume.

1. OK - HDA Intel was already at the top of the list

2. I have absolutely no idea what pavucontrol is? If I try running in a terminal I get:

The program 'pavucontrol' is currently not installed. You can install it by typing:
sudo apt-get install pavucontrol
pavucontrol: command not found


I am relunctant to try installing since I have no idea what it is or does. Also, it seems that ALSA is not installed - do I need ALSA - I thought PulseAudio replaced ALSA. Well just looked under Synaptic and ALSA-base is installed but nothing else on the list from an ALSA search.

Re: no sound

OK - sound is now working.

I played around with Kmix channels.

Turned on some that seemed like they should be enabled, but were not checked. I have no idea what changed. I tried unchecking/unenabling some that I thought I had checked/enabled, but that made no difference.

So playing with the KMix channels did something and now it's working.

Don't ask me why ?!?!

Tried testing with "System Settings->Multimedia"

Tested HDA Intel (Stac92xx Analog)

and got a popup window that said it wasn't working and that it was falling back to PulseAudio and beautiful sound came out.

Did the test with PulseAudio and sound worked.

Moved PulseAudio to the top of the list.

So it is now working - will see what happens after I need to reboot.

Thanks for the help.

I did the following command: cat /proc/asound/modules

and got

0 snd_hda_intel

whatever that means.

I had looked up Pulseaudio and they suggested the following command to see if the sound module was installed - it is:

modinfo soundcore
filename: /lib/modules/2.6.31-14-generic/kernel/sound/soundcore.ko
alias: char-major-14-*
license: GPL
author: Alan Cox
description: Core sound module
srcversion: 3A50BBE947364A4D9DB6A97
depends:
vermagic: 2.6.31-14-generic SMP mod_unload modversions 586

and I learned that pavucontrol is the pulseaudio volume control - thanks for that. The Kmix volume control works so don't know if I need pavucontrol also.

Re: no sound

So now I've got Pandora Radio Back - great.

Re: no sound

As long as it works, don't try to fix it.

It is now untouchable.

Rebooted and it is still working
