f1a36e84a7 alsa-mixer: Fix a small issue when detecting required-any
If somebody writes the line "required-any=ignore", that shouldn't
mean a required-any element needs to be present for the path to
succeed probing.

2577cc81b3 alsa-mixer: Show HDMI ports for older Nvidia cards
Some older cards do not have jack detection. This patch makes the
port still show up.
An implementation detail: the "required = ignore" line has in itself
no effect, but we have to write *something* there, or else the entire
jack detection section will be ignored by the parser.

pa_channel_position_mask_t is type defined to uint64_t, and to display
uint64_t, it's better to use PRIx64 primitives.

e02cb7fb2e alsa-mixer: Make speaker get available=no when headphones are plugged in
While developing the new UI we had to ask ourselves the question of whether
"speakers" should be considered available when headphones are plugged in.
In most cases, they are not available and therefore we should list them
as such.

OTOH, we don't want unplugging the headphones to be considered an act of
wanting to use the speakers (the user might prefer HDMI), and there might
be line-outs that keeps the speakers from unmuting anyway. So, at this point,
I think the most reasonable would be to make the speakers have
PA_PORT_AVAILABLE_NO when headphones are plugged in and
PA_PORT_AVAILABLE_UNKNOWN when they are not. But we might want to revisit
this decision once we have the priority lists up and running.

The same reasoning applies for "Internal Mic", which should become unavailable
when any other mic is plugged in.

dedf1340c6 alsa: Jack detection kcontrol implementation
Support the new jack detection interface implemented in Linux 3.3
(and Ubuntu's 3.2 kernel).

Jacks are probed and detected using the snd_hctl_* commands, which
means we need to listen to them using fdlists. As this detection
needs to be active even if there is currently no sink for the jack,
so this polling is done on the card level.

Also add configuration support in paths, like this:
[Jack Headphone]
required-any = any

...where 'Jack Headphone' should match 'Headphone Jack' as given by
ALSA (as seen in e g 'amixer controls').
"Required", "required-any" and "required-absent" is supported. Using
required-any, one can have several ports even though there is no
other indication in the mixer that this path exists.

Hi. Could you please apply the attached trivial patch so that I could drop

a103e82029 alsa: reset watermark to initial values on resume
Watermark level and latency values are not restored when
resuming, the values used prior to suspending are reused.
This leads to side effects when underruns happen and buffer
sizes are updated, PulseAudio can never meet lower latency
requirements.

Solution: keep track of watermark and latency values on sink or
source creation, and reapply them on resume to start with
a clean slate.

42d056593d alsa: Make mixer error handling more robust still
Instead of relying on the snd_mixer_* functions failing, we check for
POLLERR and POLLNVAL first. After this, any errors in handling the mixer
events are deemed fatal (that is we cause the ALSA source/sink thread to
terminate).

The case where POLLERR is set but POLLNVAL is not does not actually
occur, but we're making this a soft failure (stop polling the mixer, but
don't kill the I/O thread). If other conditions where POLLERR occurs
turn up, we need to handle them explicitly.

Thanks to Linus Torvalds for helping get this right.

fc8702ee81 alsa: Give compressed formats preference over PCM
This makes set_formats() put PCM formats lower down the list than
compressed formats since we negotiate by picking the first format in

during sink input creation.

This will be incorrect if we ever decide to do encoding in PA (for
things like AC3/DTS encoding for multichannel output over S/PDIF).
