[Pkg-alsa-devel] Bug#889294: alsa-utils: External mic via combo jack is not detected on Acer Aspire V3-372

[Vladimir K]

...but now analog-output-speaker port in pulseaudio has "availability unknown" when jack is unplugged. This prevents auto fallback when unplugging jack.
When jack is plugged in, analog-output-speaker is correctly "not available".

analog-input-internal-mic always has "availability unknown"
analog-input-headset-mic is correctly "not available" when jack is unplugged, but "availability unknown" when plugged in.
