specifically the ALSA backend explicitly offers millisecond buffer-sizes
for devices that require it e.g. recent HDA Intel via SOF (Sound Open
Firmware).
Also as of yesterday's git, today's nightly.ardour.org build
ARDOUR_ALSA_DEBUG=1024 Ardour6
Thanks, the latest version of the driver also allows setting 64 as a
period size now (even though the network side is still using 48 samples
per network packet). Others have reported that the recent driver change
allows running jackd with period 64, but on my machine it does not seem
possible at the moment to run at periods that small. I have a PREEMPT
kernel, but not PREEMPT_RT, perhaps full RT is needed, at least on my
machine, to run with periods that short.
Still investigating as I get time. I like the flexibility that network
interfaces will give, but this is definitely not going to be like using a
USB interface any time soon.
will first try to use interleaved access and then fall
back to
non-interleaved instead of the other way around.
Also found that the driver was advertising non-interleaved access as a
valid mechanism, but did not properly implement that. The latest driver
version does not set the attribute bit for non-interleaved, so I think
that problem is also solved at the driver side now.
thanks,
