I can confirm this partly. 
Yesterday, playwave gave a scattered sound (skips and many repeated
sounds). Today playwave works. I could not get xmms working
(neither yesterday nor today). This is 2.6.0-test9.

xmms was fine in test5, running at half speed in test6 and test7, 
fine in test8, broken in test9.


But I did not get the following messages:
