Comment(by Quozl):

 Partially reproduced with os11 and latest kernel e3f598e, with the
 following symptoms:
  * the signal to speakers is not turned off when headphone jack is
  * the audio is interrupted, apparently as a result of the graphics
 animation in Jukebox activity, (the same interruption does not occur using
 playmus), and this is likely to be a source of "noise" reported by Andy,

 However, I do not agree that the sound is very small.  The test file
 starts quietly.  It appears to have been normalised.  The peak sound
 energy is from 4:55 to 05:50.  The sound level of the loud section of the
 music is consistent with the test tones.

 (I expect a side by side comparison with XO-1.5 may eventually be needed.)
