[LAU] RME HDSP 9632 - amixer control

[Klaus Schulz]

Hi Georg and others.

Find enclosed my HDSPscan script. I wrote it to identify the channels ids
for using it with amixer.

It connects each in- to output, which makes it easy for you to identify the
routing you're looking for.

It is a two-stage approach to reduce the number of test cases.
First it will connect every single input - one after another - to "all
outputs" to identify the input you're looking for.
Then it'll connect the chosen input to every single output one after
another.

The test tone is generated by the script (sox) itself.

Hope some of you guys find it beneficial.

It saved me a hell lot of time.

Have fun

\Klaus
