you should use dmix with the 'ipc_key_add_uid' parameter set to false to let multiple users share the same device. > > Currently I do not use sharing of sound card that results in lockups - > app.s either waiting for hardware to be released or hang up my whole > system - I tried to run ardour2 while mplayer2 was playing a FLAC. - > Had to reset whole OS. > that sounds really weird... you should use jack sound server and configure every user .asoundrc properly, furthermore have a look at your /etc/group and add your user to the audio group, then you can use /etc/security/limits.conf or /etc/security/limits.d/audio.conf to "boost" audio performances for audio group members -r
