Public bug reported:
I installed Ubuntu Daily (20/2/2012) and I am experiencing issues with
the sound.
Specifically, I cannot record audio, neither from the internal
microphone, nor from the red input jack.
pavucontrol does not recognise any audio input from the card.
Alsa does not recognised the HDA codec:
[ 12.564311] hda_codec: CX20590: BIOS auto-probing.
(Analog audio playback is OK; did not try HDMI output yet)
