I was messing around with resampler.c in the pulsecore folder. I was
wondering about the input and output buffer sizes that are passed into
the various resampling methods. I printed out the size and the output
buffer is larger than the sampling rate ratio times the input buffer
by a large number
What is returned in the next input buffer, when the resampled output buffer
is under by a sample or two?
For example:
Input buffer size is 100 samples. You are upsampling by a factor of two, so
the output buffer size should be 200 samples.
So if you a doing some processing, and the number of
Is there a flag that specifies the amount of time that parec should be
running? parec seems to run indefinitely waiting for data to be streamed on
the monitor sink.
Thanks

What is the proper way to do volume ramping in pulse audio to avoid clicking
when changed the volume? I wrote a module to callback and change the volume
in small incremental steps, but it seems that pulse seems to apply the
volume changes on the audio buffer as a whole. Does pulseaudio take a
? If
not, then where?
Thanks

Is it possible to change the sampling rate that the alsa sink or source is
configured for? For example, in some scenarios, 44.1kHz is used, then in
another scenario, to avoid sample rate conversion and some other hardware
problems, configure the alsa device to 8kHz within the

Hi,
I'm seeing some issue with underruns/rewinds occurring on the beginning of
every sink input playback.
I see rewind requests on alsa sink of 9600 bytes. The alsa driver is
configured with the following buffer sizes
I: sink.c: device.buffering.buffer_size = 9600
I: sink.c:
Also, if i revert to pulseaudio 0.9.14, i do not see this issue happening.
I can hear the very short samples in the beginning fine.

Hi,
There used to be some test/sample code that did volume ramping on pulseaudio
git source. Recently it has been taken out. Any idea as to why, the revert
commits did not mention a reason.
I've been testing it out and it seems stable, I did have to change some of
the logic and code to get it
