Comment:

 Thanks.

 I've tested Q2E45 against Q2E48, and the older version yields 82 dBA
 during ''test /audio''.  This is a 14 dBA drop for the Open Firmware audio
 test only.  It does not affect the startup sound, Linux or Sugar.

 I've briefly checked for the changes between Q2E45 and Q2E48 that may have
 caused the lower volume.  This period covers development of manufacturing
 tests for XO-1.5 hardware, and changes to shared code.  During these
 changes there were refinements to the method used for producing sine
 waves, but no change to the volume settings.

 XO-1 is no longer in mass production, so the manufacturing test for audio
 is not required by OLPC.  That leaves use by deployments.

 I propose that:
  * those using ''test /audio'' on XO-1 be taught that the test is less
 loud after Q2E45, and that this change has no effect and no impact,
  * this ticket be closed.

 Please respond.  In particular I'm interested in why you consider this to
 be high priority.  I must be ignorant of something.
