Description of problem:
SELinux is preventing snap-confine from 'getattr' accesses on the chr_file /dev/snd/hwC0D0.

*****  Plugin catchall (100. confidence) suggests   **************************

Si cree que de manera predeterminada se debería permitir a snap-confine el acceso getattr sobre  hwC0D0 chr_file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso temporalmente ejecutando:
# ausearch -c 'snap-confine' --raw | audit2allow -M mi-snapconfine
# semodule -X 300 -i mi-snapconfine.pp
