Today I tested the latest master branch (already including your two
patches), seems it did not fix the problem. Below is my testing detail:
Install ubuntu 16.04 on my laptop.
clone the latest pulseaudio source code, checkout master branch
build the source code: ./autogen.sh;make
kill the existing pulseaudio and run the latest pulseaudio: pulseaudio
--kill && ./src/pulseaudio -vvvnF ./src/default.pa -p $(pwd)/src
On this machine, we have sound cards, sinks and ports like below:
Card#0(HDA INTEL HDMI)-> Sink#0(hdmi-stereo)->hdmi-output(priority:
5900)
Card#1(HDA INTEL PCH)->Sink#1(analog-stereo)->headphones(priority:
9000)
No speaker port at all on the PCH card?
with the new pulseaudio, I can only see one sink (analog-stereo)
through pactl list sinks at the beginning.
After I plug the HDMI cable (headphone is not plugged), I can see two
sinks via pactl list sinks, but the default sink is still the analog-
stereo, here I expect the default sink is hdmi-stereo since the
headphone is not plugged yet.
That's what I'd expect too. Is the headphone port marked as unavailable
as it should?
Then I plug the headphone, and I select the hdmi (hdmi is also
plugged in) as the default sink, after a while I unplug the hdmi
cable, here I expect the default sink is back to analog-stereo since
headphone is still plugged, but the default sink did not switch to
analog-stereo. BTW after I unplug the hdmi cable, I can still see two
sinks.
The default sink is set in pa_core_update_default_sink() in
src/pulsecore/core.c. That function uses the compare_sinks() function,
and the first thing compare_sinks() does is to check if one of the
compared sinks has an unavailable port active. Can you figure out what
goes wrong? Is pa_core_update_default_sink() not called when you plug
in or unplug things, or does pa_core_update_default_sink() really
choose a sink whose active port is unavailable?
Looking through the patch it seems to me that availability changes of
a port
do not trigger a recalculation of the default sink. Or am I missing
something?
Sorry, I was wrong. The actual commit is slightly different from the
patch in
patchwork and includes the necessary calls.
