Have you upgraded or downgraded jack_capture and/or libsndfile since then? Which version of jack_capture are you currently using? Have you tried a different format than wavex? (wav is probably the the safest format to try since it's one that has been the most tested. Wav files has a 2gb limitation though, but jack_capture automatically writes to a new file whenever it reaches that limit.) There was a problem many years ago that I used (by accident) a 32 bit integer instead of 64 bit integer. Perhaps you are using one of those quite old versions of jack_capture. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
