Comment 9 for bug 1642105

I set latency back to 10ms to maybe catch some log output.
Loaded a .m4a, et voilà, these were last lines after the dropout happened:

File is an .m4a recoded from .wav with this command:
avconv -i "$file" -vn -acodec libfdk_aac -b 320k "${file%%.$ext}.m4a"

Still can't reproduce it, though. Neither when loading the same file, nor when also playing a .m4a (even a shitty one) on the other deck.

As next step I will build a more recent kernel with preempt patch, see if that makes a difference.
