Bug#369078:

[qweo]

Hm,the problem not in alsa-oss,it's just incompatibility between new alsa version (what updated yesterday) and alsa-oss:
[19:02] (~) %ls -l /usr/lib/libasound.so.2.0.0
-rw-r--r-- 1 root root 789312 May 26 22:33 /usr/lib/libasound.so.2.0.0
                                                                      %                                                                                      [19:02] (~) %ls -l /usr/lib/libalsatoss.so.0.0.0
-rw-r--r-- 1 root root 34824 Apr 23 19:29 /usr/lib/libalsatoss.so.0.0.0

So,it normal,because alsa version is rc4,but not so bad if developers fix this bug before release :))
