Hi Adrian,
visually tested, seems to work for the HDSPe AIO.
[rocketmouse@archlinux hdspdump]$ gcc -std=gnu99 -o hdspdump hdspdump.c -lasound
[rocketmouse@archlinux hdspdump]$ ls
hdspdump hdspdump.c
[rocketmouse@archlinux hdspdump]$ ./hdspdump hw:0 > hdsp-test.dump
[rocketmouse@archlinux hdspdump]$ ls
hdspdump hdspdump.c hdsp-test.dump
[rocketmouse@archlinux hdspdump]$ ./hdspdump hw:0 write < hdsp-test.dump
hdspmixer doesn't readjust the faders after running
./hdspdump hw:0 write < hdsp-test.dump, but the meter on the mixing
console does show that it's seemingly working. I only moved one fader,
didn't run an extensive test.
It's useful, thank you.
Regards,
Ralf
