Comment 14 for bug 1710993

After add the line on /etc/apt/sources.list, update and upgrade, I get my sound muted, I reboot and unmute but stayed playing no sound, I checked the volume it seemed ok but nothing goes out, volume icon still launch alsamixergui, but it displayed Card and Chip as being PulseAudio, and have Master and Capture control, the console alsamixer stayed displaying ALSA controls. Unfortunately I can not hold this situation for now, I have a meeting soon, so I reverted the version to 0.65.1.
