Your Terminal output in http://www.alsa-project.org/db/?f=4e0a9d2b476b812267a0960a2ee9b5f30b5a9deb

shows that the Master channel and other channels in alsamixer were simply muted.... Volume was at 100%, but channel was set to "mute" You can use the M key in alsamixer to unmute muted channels.

Thanks Mark,

I had previously changed all "MM" to "00" in alsamixer without solving the
problem.
