Bug description:
  [Impact]
  The volume level changes on HP EliteStudio AIO with audio codec RTK ALC274 
doesn't seem to take any effect. The volume stays the same no matter what we 
configure the volume level.

  [Fix]
  This hardware has ALC274 codec with speaker NID 0x17 and line out NID 0x16 
for audio output. The line out is routed correctly but the speaker is not. This 
fix correct the route between speaker and the corresponding DAC.

  [Test Case]
  1. Boot and log into the HP EliteStudio AIO.
  2. Go to the sound settings in g-c-c 
  3. Make sure the audio output device is internal speaker and start playing 
audio.
  4. Adjust the volume from the sound settings and check the volume level by 
ear.

  
  [Where problems could occur]
  The patch only apply on two particular SSIDs of the particular HP model. The 
risk of regression is low.
