SELinux is preventing /usr/bin/pulseaudio from 'read' accesses on the archivo +sound:card0.

*****  Plugin catchall_labels (83.8 confidence) suggests  ********************

If desea permitir que pulseaudio tenga read acceso al +sound:card0 file
Then you need to change the label on +sound:card0
Do
# semanage fcontext -a -t FILE_TYPE '+sound:card0'
where FILE_TYPE is one of the following: crack_db_t, policykit_var_lib_t, ssh_home_t, user_tmp_t, krb5_conf_t, xserver_tmpfs_t, iceauth_home_t, plymouth_exec_t, xauth_exec_t, xauth_home_t, auth_cache_t, alsa_etc_rw_t, xdm_tmpfs_t, sysctl_dev_t, sysctl_net_t, rpm_exec_t, security_t, pulseaudio_exec_t, gconf_etc_t, mount_exec_t, shell_exec_t, consolekit_log_t, pam_exec_t, krb5_home_t, abrt_var_run_t, proc_afs_t, oddjob_mkhomedir_exec_t, xserver_log_t, var_lib_t, dbusd_etc_t, user_home_t, updpwd_exec_t, xdm_tmp_t, xserver_t, configfile, userdomain, fusermount_exec_t, domain, sysctl_crypto_t, rpm_var_cache_t, faillog_t, lastlog_t, proc_net_t, var_log_t, chkpwd_exec_t, policykit_reload_t, xdm_etc_t, xdm_log_t, gnome_home_type, abrt_t, hostname_exec_t, samba_var_t, lib_t, initrc_var_run_t, gkeyringd_exec_t, pam_var_run_t, rpm_var_lib_t, xdm_var_lib_t, xdm_var_run_t, net_conf_t, init_exec_t, afs_cache_t, abrt_helper_exec_t, etc_runtime_t, anon_inodefs_t, gconf_home_t, sysctl_kernel_t, openct_var_run_t, config_usr_t, ld_so_t, pcscd_var_run_t, user_cron_spool_t, alsa_exec_t, udev_var_run_t, xkb_var_lib_t, shutdown_exec_t, consoletype_exec_t, xdm_rw_etc_t, accountsd_var_lib_t, textrel_shlib_t, xdm_exec_t, xdm_home_t, xdm_lock_t, pam_var_console_t, rpm_script_tmp_t, system_dbusd_var_lib_t, cgroup_t, policykit_auth_exec_t, selinux_config_t, bin_t, cert_t, lib_t, usr_t, var_t, wtmp_t, xserver_exec_t, default_context_t, pam_console_exec_t, ld_so_cache_t, sssd_public_t, hwdata_t, locale_t, var_auth_t, dbusd_exec_t, etc_t, fonts_t, user_fonts_t, user_tmpfs_t, proc_t, sysfs_t, xdm_t, loadkeys_exec_t, xdm_dbusd_t, xdm_spool_t, krb5_keytab_t, fonts_cache_t, system_cronjob_var_lib_t, ssh_agent_exec_t, plymouthd_var_log_t, security_t, shell_exec_t, net_conf_t, file_context_t, xsession_exec_t, krb5_host_rcache_t, cert_t. 
Then execute: 
restorecon -v '+sound:card0'


*****  Plugin catchall (17.1 confidence) suggests  ***************************

If you believe that pulseaudio should be allowed read access on the +sound:card0 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep pulseaudio /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
