Hey,guys. When i enter sudo startxfce4after finished install all the packages completely, i got the following error:

Syncing timezone... Installing target audio...

I googled something like this, and found https://github.com/dnschneid/crouton/issues/947 . This is the issue of crouton,but since this is the fork of crouton, i guess there must be sth similar. And this is the author @drinkcat 's reply :https://bugs.chromium.org/p/chromium/issues/detail?id=398796

Totally the CRAS problem,i read the answer,found the way to solve is:

• The simplest way would be to add '--version' option to 'cras_test_client', that dumps the git commit id used to build CRAS. The commit id could be hardcoded in the executable (we don't really need to communicate with the server). I think we could make use of the ebuild variable CROS_WORKON_COMMIT for this purpose (i.e. pass it to the configure script).

But i just don't get it what that exact mean,any ideas?
