Re: [Jack-Devel] alsa_* device or resource is busy

You should really consider your approach and come up with something else. what could be conflicting here? Everything. Your login manager is probably using the card. The whole concept of integrating desktop distros with rc.local for audio is not going to fly, because the distros set device permissions based on the logged in user. There might also be a system-wide pulseaudio daemon running, probably as root. You might get away with pasuspender -- alsa_out, but I wouldn't be surprised if not, unless you wrap your su call in pasuspender. Also note that you shouldn't be using alsa_in/out at all, use zita-a2j and zita-j2a or use jackd-0.124.x where you can simply specify additional cards: $ jackd -A Intel -d alsa -d hw:DSP24,0 I don't know what you're trying to achieve, but I see mostly two options: (a) if you don't need a desktop, don't use one. (b) if you do need a desktop, use their autostart features For (b): You can have auto-login for a certain user. You can have autostart for this user. Just run your script from the usual XDG directories (or however your distro implements autostart). Also consider switching to KXstudio - a lot of work went into it to make things work. An integration effort other distros never bothered to do. Cheers
