Be wary of test scenarios for previous releases, since they need to be
reviewed in light of the release notes. ;-) I guess this is what

I've not seen that test scenario before, and I don't know what it is
intended to be testing. Can you provide further details of the test
case? Is the test case on our wiki anywhere? I could not find it in a
In the current design, your test scenario will be unreliable, because:
the playback of audio using Browse uses a graphics visualisation which
consumes roughly 95% CPU on an XO-1, and 55% CPU on an XO-1.5, and this
is sufficient to prevent idle suspend.
Minor comment on point 2 above; there is no need to type "OLPC Library"
in the address bar, because it is already present if you start a new
instance of the Browse activity. You should check that the text is
present though, because it is possible to start Browse from a journal
entry on the activity ring, and therefore the previous page visited will
be shown. To avoid this, either right-click on the Browse icon in the
activity ring and select the monochrome "Start" option, or use the
activity list to start it.
My test results for this test scenario:
- on XO-1 release 8.2.1 build gg-802-1.img stops playing the music,
- on XO-1 and XO-1.5, release candidate 2 of release 10.1.2 build os851
keeps playing the music.
