Public bug reported:
It appears that apparmor is preventing the firefox snap from connecting
to the pulseaudio pipe.
When i play any video from youtube i get the error:
Oct 8 23:32:44 javier-Ryzen-Asus kernel: [12101.229270] audit: type=1107
audit(1633750364.844:79): pid=850 uid=103 auid=4294967295 ses=4294967295
subj=unconfined msg='apparmor="DENIED" operation="dbus_method_call"
bus="system" path="/org/freedesktop/RealtimeKit1"
interface="org.freedesktop.RealtimeKit1" member="MakeThreadRealtimeWithPID"
mask="send" name="org.freedesktop.RealtimeKit1" pid=14843
label="snap.firefox.firefox" peer_pid=1073 peer_label="unconfined"
Oct 8 23:32:44 javier-Ryzen-Asus kernel: [12101.229270]
exe="/usr/bin/dbus-daemon" sauid=103 hostname=? addr=? terminal=?'
And no audio is played. If i play the same video in another browser it
plays just normal.
Checking "snap interface audio-playback" gives:
summary: allows audio playback via supporting services
plugs:
- discord
- dolphin-emulator
- firefox
slots:
- snapd
and
"snap connections" gives:
Interfaz Enchufe Ranura
