I just noticed I still had a dsnoop/dmix set up and renamed asound.conf for retesting.Now at least arecord doesn't crash the system anymore, but it only returns silence (Despite a mic being connected). ossplay still crashes though and strace isn't of much use.Running ossplay causes a sys reset so fast the strace output cannot even be flushed to disk anymore, neverless be up long enough to read it on the screen.
