[mako] No audio in the headphones with a two pins jack unless plugged in after the call

[Omer Akram]

1. connect a 2 pin 3.5mm headphones into your phone and make a call

What happens:
There is no sound in the headphones and the phone's earpiece works for the call. Now if you pull out the headphone jack and plug it in you can hear the sound in the headphones.

On the end if we connect a 3 pin headphones (the one with a mic in it) things work pretty well and there is no need to reconnect the headphones.

I have initially reported this for telephony service but I think its pulseaudio issue.

Confirming that using a 2 pin headphone I can the microphone input sent to my headphones, or no input at all. In addition, the call volume starts out muted.

I was able to reproduce this one today. The port switch (to headphones) is failing on kernel level with the following message: "Slim close tx/rx wait timeout" (and subsequent follow-up errors).

I suspect another 'feature' of Qualcomm's kernel driver is that you can't switch ports while PCMs are running, or you'll get the error message above. Thus, we need to suspend PulseAudio's PCMs temporarily while switching ports.

Setting to incomplete while waiting for someone to test the patch.
