-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I recently built ardour 2.5 for witch I needed to build a recent jackd from source. Everything went fine but starting jackd with -dalsa fails with segmentation fault: zettberlin@zettberlin:~$ /usr/local/bin/jackd -R -dalsa -dhw:1 -r44100 - -p512 -n3 no message buffer overruns jackd 0.109.2 [...] JACK compiled with System V SHM support. loading driver .. apparent rate = 44100 creating alsa driver ... hw:1|hw:1|512|3|44100|0|0|nomon|swmeter|-|32bit control device hw:1 configuring for 44100Hz, period = 512 frames (11.6 ms), buffer = 3 periods ALSA: final selected sample format for capture: 16bit little-endian ALSA: use 3 periods for capture ALSA: final selected sample format for playback: 16bit little-endian ALSA: use 3 periods for playback Segmentation fault trying to start it with ffado yields this one: zettberlin@zettberlin:~$ /usr/local/bin/jackd -R -dfirewire -r96000 -p512 no message buffer overruns jackd 0.109.2 [...] JACK compiled with System V SHM support. loading driver .. 0669831650: Debug (PosixThread.cpp)[ 96] Start: Create RT thread 0x8079ba0 with priority 14 0669885965: Debug (PosixThread.cpp)[ 76] ThreadHandler: ThreadHandler: start 0x8079ba0 0674219575: Debug (bebob_mixer.cpp)[ 170] addElementForAllFunctionBlocks: Adding elements for functionblocks... 0674219603: Warning (bebob_mixer.cpp)[ 176] addElementForAllFunctionBlocks: No BeBoB audio subunit found Segmentation fault The latter looks like I missed something when building ffado - help on this would also be appreciated. Nevertheless the most evil thing is the first one: it wont start with -dalsa what could be wrong here? best regards HZN
