I'm now pretty sure I made a mistake when I thought I solved: I simply used
a different Android file system (of which I don't have source... of
course).
So I really need some guidance here?
Someone who could help me in fixing my tinyalsa implementation?
What should I check first?
How should I adapt the mixer_paths.xml to my device?
thanks!
