hi all, on my workstation, i am running pulseaudio with jack as backend. however, i have some troubles with this setup. i have two audio devices on this machine, the onboard audio chip of the soundcard and an rme hdsp (pci+multiface). when the multiface is not connected, the whole computer reacts very slowly. like i click on a menu and it takes something like 10 seconds for the dropdown menu to appear. i suppose, pulseaudio tries to start jack, but doesn't succeed, because it cannot open the hdsp device ... i am not sure, what is the best way to handle this use case, but it took me quite some time to figure out, that the odd desktop behavior is related to pulseaudio trying to launch jack ... maybe it is possible to switch the pulseaudio backend to the null backend, if jack cannot be launched? cheers, tim -- tim at klingt.org http://tim.klingt.org Only very good and very bad programmers use goto in C
