summary: Ensure that the pulseaudio interface works
details: |
Historically snapd offered the pulseaudio interface which allowed both
playback and recording capabilities.
The test exercises that both audio playback and recording are really governed
by the interface connection.
# Only classic Ubuntu has the pulseaudio mediation patches. Ubuntu 14.04 is unsupported on the desktop.
# TODO: extend tests.session and run this test on 14.04 as well.
