Hi all,
Hi!
I have a RME madi fx card, but i found out that the
minimal buffersize
for those cards is 8192 samples, which is way to big for my use.
Hardware buffer size. This buffer is divided into sub-buffers (periods)
depending on what you configure.
If you choose 32 samples, then it's 8192/32 == 256 periods that fit into
one buffer. You get an interrupt every 32 samples, and ALSA reads the
just completed sub-buffer.
The HW buffer size really has zero relation to your RTT.
Spin up jackd and then use Fons' jack_delay. Maybe we have to add
buffer_size_min to the driver, but I'm pretty sure returning the card is
the entirely wrong approach.
