Comment 24 for bug 303679

OK fixed it now, after 3 weeks of graft.....yes FIXED

I have no /etc/modprobe.d/alsa-base.conf

I have the default /etc/asound.conf

pcm.pulse {
    type pulse
}

ctl.pulse {
    type pulse
}

What you need to do to get your:
card 0: CA0106 [CA0106], device 0: ca0106 [CA0106]
working is to mute IEC958 when in alsamixer, 2nd one in on the [Playback] tab

Yes MUTE IEC958...................................music to my ears.

Then save the config by running:
sudo alsactl store 0 (or card number.....)

Hope this helps you chaps
