Ubuntu usually has Pulse Audio running, which claims and manages the
alsa devices. Try default:0 or pulse:0 as device, this is exposed by
Pulse Audio as ALSA interface.

BTW: If you have problems hearing something, check with alsamixer if all
channels are unmuted. Press "s" in alsmixer to select your sound
interface. Pulse Audio messes with the ALSA devices and sometimes leaves
some channel in a non-favourable state.
