I for one would love to see the option to have the HDSP 9652 behave the
same way as RME9652.. I ended up with 3 different cards in 3 otherwise
identical systems (Digi9636. Digi9652, and HDSP9652) anything to make
them look more alike would be great.
One problem Ive noticed with the Digi9636 however, and im still waiting
to see it happen on the other systems, is that it stops recording after
a while if I run the following loop:
while true; do
arecord -D plug:hw:0 -t wav -c 18 -r 22050 -I -f S16_LE `date +%s`.wav;
done
after a few days it ends up in a loop
ioctl(4, 0x80044121, 0xbfffee18) = 0
poll([{fd=4, events=POLLIN|POLLERR|POLLNVAL}], 1, 1000) = 0
killing arecord doesnt fix it, a reboot does. Anything I can do to
figure out what state ended up in ?
RME Digi9636 (Rev 1.5) with alsa-lib|driver 0.9.4 on kernel 2.4.20smp
