I thought it was the last of my questions but I have
two more, of this
is the first mail.
My presonus 1818vsl seemingly defaults to 44100 Hz never mind if you
configure it to 96000Hz with the windows mixer.
It seems as soon as you close down the windows based presonus audiobox
software it defaults back to 44100Hz and soesnt keep it in memory when
you use it on Linux.
Questions:
1) I need to confirm the above.
I don't have this issue. The device works fine at 44.1k and 48k. I don't
use it at 96k.
I dimly recall users reporting various issues on Linux after using the
1717VSL on windows once, which resulted in a broken firmware update.
That was 2013-ish though. IIRC the solution was flashing the firmware.
That was reported on LAU or LAD.
If you still have access to a windows box, update the firmware as
described at
https://answers.presonus.com/17746/cannot-switch-samplerates-audiobox-1818v…
Is there any way jack can report the bitrate of the
data it receives
from usb driver
[..]
Probably not. Jack facilitates inter-application communication in
userspace. Hardware I/O on Linux happens at lower level.
you can try https://community.ardour.org/files/adevices.sh which probes
/proc/asound/
