If I can just get full duplex, the game is on! Is Ubuntu Studio meant for musicians or for computer scientists? ALSA sees USB sound card, Ardour does not failed to open audio device I need a hand with configuring my machine more Recent Forum Comments @Seb: it's called harlequin20 min 20

It would be a pity if it turns out to be a simple issue that could've saved you another 2-3 hours installing and configuring. Also another logitech just wireless mouse I have. I'm also in the process of packaging some newer versions of music software for the RPi and thinking about setting up a repository. Your wiki is already of a great help.

For example I have 'memlock 1500000' in a box where I have 2GB of RAM These changes need a reboot to take effect. I tried adding the rtprio and nice options to limits.conf myself and then rebooting, but I still get the error. BTW does anyone know if the newest ubuntu due out will contain these audio features?

You will then need to reboot and choose the realtime kernel from GRUB (the bootloader). Quote Postby pkslot » Fri Apr 02, 2010 8:20 pm AutoStatic wrote:Which problems? A great resource for "linux musicians": www.linuxmusicians.com Cheers! apt-get install ubuntustudio-audio should do the trick.

Normally the ubuntustudio packages take care of both these conditions. Ubuntu Studio controls didn´t seem to have a spot to add the rtprio switch, so I just added them all with gedit. hw:0|hw:0|64|3|48000|0|0|nomon|swmeter|-|32bit

If /etc/security/limits.d does exist on your machine, then you will need to create and edit a file called /etc/security/limits.d/99-realtime.conf. No one listen to Zathras...
