a6974a6c83 Don't try to read the internal capture buffer into itself 2014-05-14 21:20:28 -07:00

f311f74001 Avoid freeing an in-use capture buffer
When stopping, ALSA may capture into its own storage buffer. Do not free
the storage buffer if it first reads from it.

1fb9311d82 Lock the device before calling aluHandleDisconnect
PulseAudio causes an assert if being relocked inside a callback on the worker
thread, where aluHandleDisconnect is called. We can assume it's already locked
there, so just make sure the device is locked before being calling it.

0865db564f Move the device lock into the backend function table
For backend-specific implementations: this should hold the audio mixer loop for
playback devices, and provide recursive mutex behavior.

ac4fc4026c Add a device method to retrieve the active latency
This is effectively the time until the next update will be heard by the user,
or the closest approximation thereof, in nanoseconds.

051195a991 Avoid failing if ALSA can't set a buffer or period time near to our request
These functions should not fail, but there seem to be bugs that cause them to
sometimes. We're flexible enough to handle almost anything it throws back at us
though, so anything is better than nothing here.

92827cc467 Clamp the ALSA buffer time between min and max if setting near fails
It seems there's some bugs with snd_pcm_hw_params_set_buffer_time_near that
cause it to return "invalid argument" despite a valid nearby buffer time being
available. Clamping the buffer time seems to mitigate the issue a bit.

fe6e532c87 Use a separate backend callback to start playback of the device
This allows us to properly update the ALCdevice and its resources with the new
parameters before starting playback, instead of expecting the mixer to block
and wait after it has begun.

This also lets us avoid holding the device lock while resetting and starting
the device, which helps prevent lock inversion on some backends (ie, one thread
locking A then B, and another thread locking B then A), ultimately allowing
certain backends to asynchronously update the ALCdevice without risk of lockup.
Capture still has issues here, however.
