Binary package hint: pulseaudio
I think this usb audio device ( Sony VirtualPhones) used to work in past versions of Ubuntu (not sure which).
Now it appears in some places and not others which I check and fails to provide audio.
Yes, the device is powered on and the headphones too; the volume is turned up ( I can hear noise at
peak levels).
I think all the details are provided by ubuntu-bug, but let me know if you need more info.

Erase all of /etc/asound.conf and ~/.asoundrc*, then logout and login. They're clashing with PulseAudio due to unfortunately poor naming of the usb audio device by the manufacturer.
