Here is the pulseaudiolog. I followed the steps described in https://wiki.ubuntu.com/PulseAudio/Log. I only had to do a 'sudo killall pulseaudio' instead of 'killall pulseaudio'
During the log, I : - launched pulseaudio for my session 'LANG=C pulseaudio -vvvv --log-time=1 > ~/pulseverbose.log 2>&1' - switched from "Analog stereo duplex" to "Stereo digital IEC ..." (don't understand why there's only a digital stereo choice since ubuntu's switch to pulseaudio? It was digital 5.1 before. But that's not the matter here...) - used the test for speakers (left and right only). I had no sound output. - switched back to "Analog stereo duplex" - and killed pulseaudio.
