Stop output messages from cvlc

Question

cvlc --play-and-exit /usr/share/sounds/My_Sounds/Alarm-sound-buzzer.mp3 2> /dev/null

When I use this, I get these irritating messages like

Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 65536
  Mono:
  Front Left: Playback 19661 [30%] [on]
  Front Right: Playback 19661 [30%] [on]

Any to suppress them?

@doug Yes. With mp3 files. I am using Ubuntu Mate 18.04. It never occurred with 16.04. — fixit7, Aug 12 '18 at 12:29
If you were to run the same commands but using vlc instead do you see the same? If so what does just plain vlc produce in terminal? — doug, Aug 13 '18 at 12:12

Instead of just redirecting stderr with 2>, replace it with 2>&1 to redirect both stdin and stderr to /dev/null

cvlc -q --play-and-exit /usr/share/sounds/My_Sounds/Alarm-sound-buzzer.mp3 > /dev/null 2>&1

It did not help. – fixit7 Aug 12 '18 at 04:31
@fixit7 try adding the `-q` flag as shown – Amith KK Aug 12 '18 at 06:49
-q did not help. Did you try this out? – fixit7 Aug 12 '18 at 07:38
@fixit7 It seems to work for me even without the `-q` flag – Amith KK Aug 15 '18 at 04:46

This can be made to work by redirecting all output (error and normal output) to /dev/null

cvlc --play-and-exit /usr/share/sounds/freedesktop/stereo/bell.oga  > /dev/null 2>&1

Don't you mean `... >/dev/null 2>&1` (mind the first `>`)? – David Foerster Aug 15 '18 at 21:22
This works. cvlc --play-and-exit /usr/share/sounds/My_Sounds/Alarm-sound-buzzer.mp3 > /dev/null 2>&1 – fixit7 Aug 15 '18 at 22:15
