Hi,

Slackware64 14.1 KDE (full install)

I had some Microsoft Lifechat LX3000 headphones plugged in and they worked fine, well the speakers did not sure of the mic.

Now I've unplugged them I seem to have lost all sound on the system on all user accounts through the normal speakers.

If I look in 'Audio Setup' the LX3000 is listed but greyed out. I get a popup on login saying they have stopped working and the system is reverting but there is no sound, not in firefox either. I followed the howto at Slackdocs

http://docs.slackware.com/howtos:har...s_on_slackware

but no joy. The Noise.wav in /usr/share didn't play on any combination. As per that article I have:

No joy with alsamixer and I created the .asoundrc but that didn't work either. I think I might need to get rid of the trace of the headphones maybe?

I've googled and searched on here but there's a lot of stuff similar to the Slackdocs article, I've not really managed to make any progress.

One other thing I did try on one of the accounts was renaming .kde to .old-kde then logging out and in again but that didn't work either.

I guess that is a usb device ?? . open a terminal assume root command lsusb make sure it is plugged in ok.

if it fails to read that usb device then send the 19 dollar headset back to the company. I have been through 2 of those and a couple hp's'
the wire where it goes into the usb coupler go bad from simple stretch etc.

if lsusb does list your device then it is time to open up alsamixer press F6 to see all the hardware. then set it.

Last but not least try plugging it into a different usb slot or switch one.

if lsusb does not read it then the kernel is not loading it. and if the kernel is not loading it the device is dead.
or you have bios set up problems.

My last HP usb digital head set did that before it died it was greyed out all the time. Wiggle it and then it would work then die.

Sorry Drakeo, it's not the headset I'm trying to get working, it's the sound through my computer speakers. I unplugged the headset and since then have had no sound at all for any user. The headset seems to have killed all sound.

Managed to get rid of the headphones from Audio Setup by running:

rm $HOME/.kde/share/config/phonondevicesrc

for each user then logging out and in again. Still no sound though. I'll try working through the Slackdocs page again later when I get more time.

That time it worked following the Slackdocs page, maybe getting rid of the headphones from Audio Setup helped.

Sorry Mis read it so I am glad you have it back to default again system wide. And default is your analog motherboard sound card.
if you had a ~/.asoundrc and that device is gone that would cause that. Then going into KDE settings and setting the devices you want for default
helps then restarting KDE. and slackdocs works well. Since your aplay -l was your on board sound card as default and you had no sound.
I just figured you need to turn up the volume or set the channel for your output.

Like my card default output is channel 2 but that is not what I have my speakers on mine are on channel 6.

I think it may have been something to do with me creating .asoundrc files, thanks for helping.
