I have created a network namespace to separate connections through a VPN, and it runs as the same user account as I use for everything else; however, it is not able to play music/use microphone

inside the namespace:


aplay -l  
card 2: Generic_1 [HD-Audio Generic], device 0: ALCS1200A Analog [ALCS1200A Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 2: Generic_1 [HD-Audio Generic], device 1: ALCS1200A Digital [ALCS1200A Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0  



arecord -l

card 2: Generic_1 [HD-Audio Generic], device 0: ALCS1200A Analog [ALCS1200A Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 2: Generic_1 [HD-Audio Generic], device 2: ALCS1200A Alt Analog [ALCS1200A Alt Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I also tried running as another user, but the effect is the same, which is why for simplicity I resorted to using the same user that can play/record normally

what should I look for in configuring it ?

    It seems that a namespace only has access to process that originates inside itself

    systemctl --user list-units 
Failed to connect to bus: No medium found

    as we can see, the same user doesn’t have access to other processes so we would need to duplicate every process above the namespace until we could acess the media

    would duplicate of everything - pulsewire, dbus, etc - even work ?
