Which buffer sizes did you try? Did you try powers of 2?
There is a PortAudio test program called pa_minlat
, maybe that gives some insights?
Did you try setting blocksize=0
and varying latency
?
PortAudio under Unix currently uses a backgroud thread that reads and writes to OSS.
OSS is an audio backend that hasn't really been used for decades. I guess you are using ALSA?
You must also set PA_MIN_LATENCY_MSEC
That's something I have never heard before, and if you search for it in the PortAudio source code, it only appears in the file https://github.com/PortAudio/portaudio/blob/master/src/hostapi/dsound/pa_win_ds.c, which is irrelevant for Linux.

if you had a chance to see my feedback
Yeah, I've seen it, it's kinda hard to read. Can you try formatting it a bit nicer?

Please let me know if it's good or not.
Still not great.
Maybe you should use the web interface instead of replying by e-mail.

Hi Mathias,
I have not tried the pa_minlat yet. Are you referring to this? --> https://portaudio.com/docs/v19-doxydocs-dev/pa__minlat_8c.html#details

yes.
