[SOLVED] Did a full update - now no sound

I previously updated couple weeks ago.

Already ran alsaconf , reinstalled alsa, ran pcc sound config, rebooted multiple times to no avail.

I think the various sound config files conflict. This is what I have:

/etc/modeprob.conf

install scsi_hostadapter /sbin/modprobe ata_piix; /sbin/modprobe ahci; /bin/true
install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe uhci_hcd; /bin/true
options ipv6 disable=1
options snd-ac97-codec power_save=1
alias sound-slot-0 snd_hda_intel

/etc/modprobe.d/sound

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel

/etc/modprobe.d/snd-options

options bt87x index=-2

/etc/modprobe.d/snd-oss

install snd /sbin/modprobe --first-time --ignore-install --all snd snd_pcm_oss snd_seq_oss snd_mixer_oss

/etc/modprobe.d/snd-usb-audio

install snd-usb-audio test -f /var/lock/subsys/alsa && /sbin/modprobe --first-time --ignore-install snd-usb-audio

/etc/modprobe.d/blacklist-pclos

Run   alsamixer or qas mixer or other such to see if some level is zero or muted

THANK YOU SO MUCH!

I ran alsamixer and discovered a control called auto-mute that became enabled. I disabled it and now have sound.

I turns out it is also available in kmix but was not visible.
