Public bug reported:
Description: Ubuntu 16.04.2 LTS
Release: 16.04
unity-control-center:
Installed: 15.04.0+16.04.20160705-0ubuntu1
Expected Behaviour: When I start a recording with a specific audio
source, changing the default audio source has no effect on the recording
source.
Actual Behaviour: The audio source changes to the default one always,
even if I specified one before.
So far I tried this using parecord and gstreamer. After I start a
recording, if I go to Sound > Input and change the source in the "Record
sound from" box, the recording source changes.
This happens even when I specify a device explicitly. Examples:
GStreamer: gst-launch-1.0 pulsesrc
device=alsa_input.pci-0000_00_1b.0.analog-stereo ! pulsesink
pulse: parecord --file-format="wav" -d
alsa_input.pci-0000_00_1b.0.analog-stereo TEST.WAV
In both cases, changing the source in the config changes the audio being
recorded.
I thought this was a pulse issue, but changing the default source with pactl
does not have this behaviour (and the change does appear in the sound control
panel)
How to change the default audio source with pactl:
pactl set-default-source alsa_input.usb-046d_081d_96D1FD90-00.analog-
mono
I suspect this has something to do with how the control center changes
the default audio source, so a clarification in how this happens could
be very helpful.
