I'm not using an AD1984A; alsamixer tells me it's an IDT 92HD71B7X. It worked fine until and including Ubuntu 13.04, and broke with 13.10. Note that my "pactl list" output (see attachment) is generated *after* fixing the Pulseaudio config files (see my earlier comments). I can repeat the procedure on a pristine Pulseaudio setup if necessary.
