Sound abruptly stopped working in KDE

Like the title says. I'm using 2009 Spring, and sound worked fine for a long time.

 

About half an hour ago I tried to fire up my WoW client and got silence.

 

Relog. Silence.

 

Reboot even! Silence.

 

Okay, so I went into the MCC and picked hardware->sound. Everything looks okay to me. Under troubleshooting it lists the "classic" sound troubleshooting commands, from which I got these results:

 

[root@localhost javaguy]# lspcidrake -v | fgrep -i AUDIO

bt878 : Brooktree Corporation|Bt878 Audio Capture [MULTIMEDIA_OTHER] (vendor:109e device:0878 subv:0070 subd:13eb)

snd_ice1724 : VIA Technologies Inc.|VT1720/24 [Envy24PT/HT] PCI Multi-Channel Audio Controller [MULTIMEDIA_AUDIO] (vendor:1412 device:1724 subv:14c3 subd:1705)

snd_hda_intel : nVidia Corporation|MCP61 High Definition Audio (vendor:10de device:03f0 subv:1043 subd:8234)

 

 

 

grep sound-slot /etc/modprobe.conf

alias sound-slot-0 snd_ice1724

alias sound-slot-1 snd_hda_intel

What I understand of this looks fine to me, but I'm far from being a guru.

 

Again, it worked before. :(

 

Any ideas?

I assume you've checked all the obvious things already, but just to make sure you haven't overlooked something:

Is the whole thing muted in kmix?

Are your headphones plugged in and hiding under your desk?

Are your external speakers switched off?

 

I usually find I've done something dumb like that when the whole sound system isn't doing anything... :P

this thing recently happened to me....I did the same as javaguy...but it didn't worked

 

so I tried my last shot XD and clicked "Reset Sound Mixer to default values"

 

and it works again! B)

 

so if you wanna try ...
