:SELinux is preventing /opt/google/chrome/chrome from 'execute' accesses on the file /usr/lib64/libasound.so.2.0.0.
:*****  Plugin restorecon (94.8 confidence) suggests  *************************
:If you want to fix the label. 
:/usr/lib64/libasound.so.2.0.0 default label should be lib_t.
:Then you can run restorecon.
:# /sbin/restorecon -v /usr/lib64/libasound.so.2.0.0
:*****  Plugin catchall_labels (5.21 confidence) suggests  ********************
:If you want to allow chrome to have execute access on the libasound.so.2.0.0 file
:Then you need to change the label on /usr/lib64/libasound.so.2.0.0
:# semanage fcontext -a -t FILE_TYPE '/usr/lib64/libasound.so.2.0.0'
:where FILE_TYPE is one of the following: bin_t, user_tmpfs_t, lib_t, ld_so_t, abrt_helper_exec_t, chrome_sandbox_nacl_exec_t, textrel_shlib_t, chrome_sandbox_exec_t. 
:Then execute: 
:restorecon -v '/usr/lib64/libasound.so.2.0.0'
:*****  Plugin catchall (1.44 confidence) suggests  ***************************
:If you believe that chrome should be allowed execute access on the libasound.so.2.0.0 file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep chrome /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Michel Alexandre Salim 2012-03-31 22:36:01 EDT
This also happens with -109, but as it turns out I had to restorecon the libasound .so file
