Hi MW_FFM2020,

/etc/asound.conf has rw permission for group staff, so tc will have
permissions to edit the file.


Code:
--------------------
    tc@piCorePlayer:~$ la /etc/asound.conf
  -rw-rw-r--    1 root     staff          578 Jun  7 01:29 /etc/asound.conf
  
  tc@piCorePlayer:~$ vi  /etc/asound.conf
  
--------------------


If the group staff only had r permissions, then you add the sudo command
to gain access via the user permissions (root in this case).


Code:
--------------------
    
  tc@piCorePlayer:~$ sudo vi  /etc/asound.conf
  
--------------------


regards
Greg
