Suddenly no sound


Hi

Sorry it is such a useless subject line, but I don't know what else to say.

I have been using Suse 11.1 with Firefox and more recently Opera since July 2009.

Over the past couple of days I have lost sound. There is no sound from CD's or watching youtube. However, I don't think it is hardware as when I turn the machine on I get the welcome sound. And I jump when I switch it off as I have turned the sound up and I get the goodbye sound.

Just a thought this weekend I downloaded Skype. As far as I can see it doesn't start when I boot up the machine. I have just started Skype and I get the welcome sound from that. If it is Skype that is causing the problem I supose I can uninstall as I only have speakers and not a microphone.

So there is no sound out of Opera or Firefox or cd's.
Can anyone give me some tips of where to look for the problem?

Thank you.

Hi

I have carried out a test

speaker-test -c2 -twav

The nice lady says 'front left' front right'. So there is nothing wrong with my hardware. There is something wrong with the line of code as I couldn't work out how to stop it. Only by 'ending the process' in system monitor.

Regards

Hi,

Today the sound is fine on everything. When I turned on my machine this morning it did an update. I am hoping it is sorted now.

I couldn't find /etc/asound.conf, but found /etc/asound-pulse.conf

Code:
# PulseAudio plugin configuration

# Let's create a virtual device "pulse" for mixer and PCM

pcm.pulse {
    type pulse
}

ctl.pulse {
    type pulse
}

# Let's make it the default!

pcm.!default {
    type plug
    slave.pcm {
        type pulse
    }
}

ctl.!default {
    type pulse
Type  :quit<Enter>  to exit Vim                               1,1           Top
And I also found

Code:
state.SI7012 {
        control.1 {
                comment.access 'read write'
                comment.type BOOLEAN
                comment.count 1
                iface MIXER
                name 'Master Playback Switch'
                value true
        }
        control.2 {
                comment.access 'read write'
                comment.type INTEGER
                comment.count 2
                comment.range '0 - 31'

                value.1 31
        }
        control.3 {

Hi

Today is a day where I have no sound from Firefox or Opera. I tried closing and reopening them with no success.

asound-pulse.conf
Code:
# PulseAudio plugin configuration

# Let's create a virtual device "pulse" for mixer and PCM

pcm.pulse {
    type pulse
}

ctl.pulse {

# Let's make it the default!

pcm.!default {
    type plug
    slave.pcm {
	type pulse
    }
}

ctl.!default {
    type pulse
}
and asound.state

take a back up of your asound-pulse.conf

edit the content

Quote:
pcm.!default {
type plug
slave.pcm {
type pulse
}
with the following one:

Quote:
pcm.!default {
type plug
slave.pcm "dmix"
}
restart the system.

dmix is a plugin that allows you to open multiple threads. So that more than one application can use the speaker(s) parallely. Otherwise audio device will get locked under first application that started using the speaker(s). This lock will not be released unless you reboot.

Regarding "type pulse" . . . . . even I don't know what it is
may be related to pulse audio

Hi,

The sound has worked for a couple of days. I uninstalled Skype also. Yesterday, it wasn't working, I did you as suggested, but I didn't restart. I have turned it on today and it is working.

I hope this is it sorted now. Watch this space.

Thank you.

Hi Everyone,

I have had sound until today, where it is gone again. I am wondering if I should do a fresh install?

My wife had the same problem, although now we are having other problems, but we have sound now all the time each boot.

What I did to fix it? Remove Pulse. Get Rid of it.

Anyways, that my fix. It work. Sound works. What is pulse for anyways. I dont have network music going on, why would I need pulse installed, and why is it installed by default?


Not sure what removing pulse might have done to my config stuff, I removed my sound card frim yast and let it refind it and reconfigure it, I then ran the alsa config command util to get things back to norm.

Anyways, hope this helps.
