Title:
  HDMI audio does not work on GeForce GT 220 with lts-utopic kernel

Status in ALSA driver:
  New
Status in linux-lts-utopic package in Ubuntu:
  New

Bug description:
  HDMI audio does work on trusty kernel 3.13, but does not on the lts-
  utopic 3.16 kernel. Which (probably) means HDMI audio does not work on
  other nvidia cards, and also on 14.10 utopic. I can playback sound in
  MythTV frontend using 'ALSA:dmix:CARD=NVidia,DEV=7', but using the
  same with speaker-test gives:

  $ speaker-test -D dmix:CARD=NVidia,DEV=7

  speaker-test 1.0.27.2

  Playback device is dmix:CARD=NVidia,DEV=7
  Stream parameters are 48000Hz, S16_LE, 1 channels
  Using 16 octaves of pink noise
  Sample format not available for playback: Ongeldig argument
  Setting of hwparams failed: Ongeldig argument

  
  $ lspci -vvv | grep -i nvidia | tail -n3
