Hello I use pjsua / python 1.6 and I wonder if it is possible to refresh the list of sound devices. case concerns a USB sound card. I suppose that the list of sound devices is created once at startup library. import time import pjsua as pj lib = pj.Lib() lib.init(ua_cfg, log_cfg, med_cfg) while 1: print len(lib.enum_snd_dev()) time.sleep(5) I connect my sound device during the loop, and nothing changes. Of course, if the card is plugged in before the start of the program everything works perfectly. Little help ? -- ?ukasz Wr?blewski DDarko.org Hostowisko.pl NRI.pl
