It seems like I made a loop with little success but I couldn’t get rid of the crackling. So I reverted everything so I get clean sound. But I am still stuck at launching jack_capture - even as root.
sudo jack_capture --daemon -c 5 -mb -tm -f flac
Cannot read socket fd = 5 err = Success
CheckRes error
JackSocketClientChannel read fail
Cannot open jack_capture client
JackShmReadWritePtr1::~JackShmReadWritePtr1 - Init not done for -1, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
Any further ideas what I could inspect / try?
