Dear All,
I am currently working on an audio program (aldrin) which uses libbzub driver http://trac.zeitherrschaft.org/zzub/browser/trunk/src/libzzub/driver.cpp for accessing the sound card. Libzzub, in turn uses rtaudio version 3.03, which is part of the libzzub source tree.
The problem arises when I am running a jack server using my sblive, but specifying the default interface (hw:0).
On startup, a vast number of xruns are generated (>200) and jack either falls over, or the computer almost completely locks up.
This appears to be caused by rtaudio probing the alsa devices whilst jack is running. Interestingly, if I specify a sub-device (hw:0,3), or the integrated sound card (intel), no xruns are generated.
I am wondering if this problem is arising because of a bug in the emu10k1 driver, or a problem with the way rtaudio probes alsa devices, or because it is a bad idea to probe alsa devices while they are being used by jack???
Best wishes,
James
