40ba9db406 Only call Pulse functions from under a lock 2010-07-31 16:07:04 -07:00
Chris Robinson
d886fb118b Signal the Pulse mainloop on underruns 
Otherwise there are (rare) risks of not getting signaled after writing the
amount of free audio data the client knows about, leading to a mixer loop
lockup

40dd1fb853 Add a backend callback to get the device time 
The method should monotonically count the number of nanoseconds the device has
active contexts

969818db6f Use a 100ms capture buffer minimum for PulseAudio, with 50ms fragments 
This better matches what is given with the WaveIn backend

33234d605a Don't attempt to look for more samples from Pulse after a disconnect 2010-06-05 00:09:45 -07:00
Chris Robinson
c6defe9a6d Read PulseAudio's capture data into the ring buffer when querying the sample count 
This ensures we have all the samples available that the app knows about

ebccfa93c3 Don't unload libs when they're not needed 
Some libs don't really like being unloaded and reloaded all the time, and the
benefits aren't that great

f89c9f7ea4 Connect a pulse stream on device open, to make sure the device isn't suspended 
Also use the opportunity to get the stream's device's name, so later reset
calls will use the same device

d4159430f0 Set the buffer length for Pulse when opening the device 
So it will properly scale with context frequency requests

14255a38fc Pulse's buffer size is not a good measurement for the update size 
Lie and say 20ms instead, since there is no stable method to get such info

56379bffac Use pa_channel_map_superset only when available with PulseAudio 0.9.15 
pa_channel_map_equal can otherwise detect some compatible output modes

fd794b44b2 Use pa_stream_begin_write when available for "zero-copy" writing 
Must be compiled against 0.9.16 or newer to be available. It will fall back to
the old method if the function is not available at run-time.
