Public bug reported:
I recently added the module-tunnel-sink to my pulseaudio config to have
an option to tunnel audio to remote server. The tunnel works fine, it
shows up in 'pavucontrol', and audio sounds fine. However, when the
tunnel is connected, if I go to the 'playback' tab in pavucontrol and
switch audio that is currently playing to 'internal analog stereo' on my
T500 laptop, then audio stops playing on the remote server, but it never
starts on the local laptop speakers. As a further symptom, when I
press pause on the audio (it's mog.com playing in google chrome), the
audio stops within a second, but when I undo pause, it takes maybe 15
seconds to startup. It doesn't do that when the tunnel is not present.
I was hoping to be able to use the tunnel so I could 'seamlessly' switch
between remote and local audio, but at the moment, it seems like setting
PULSE_SERVER when starting google chrome and connecting directly to the
remote server seems to be more stable. But the downside is it requires
restarting chrome each time I want to switch.
It'd be great if I could get the tunnel to function seemlessly. I've
turned on DEBUG level logging on the pulseaudio client and server. I
don't see much helpful there except things about buffer underruns
periodically and 'Wakeup for ALSA' messages. But the underrun related
pauses are only a few hundred milliseconds.
