Please post the output of $ grep RTIRQ_NAME_LIST /etc/default/rtirq Your sound device doesn't share it's IRQ, but it has got a bad priority. The rtirq default is to care about snd drivers, but Ubuntu Studio has got the tendency to use current lowlatency kernels, but stay with outdated rtirq scripts, that don't fit to the kernel. Please also post the output of $ sudo apt-cache policy rtirq-init $ uname -rm On Sun, 2014-07-27 at 16:24 +0530, Shubham Mishra wrote: > So I should get an external audio interface which has a mic preamp and > midi in and not use onboard card at all?
