Try disabling wifi in the BIOS/UEFI during boot. This can have dramatic
results.

Hey guys!Recently I've bought a Lenovo IdeaPad B590 laptop. As it is =
announced as an Ubuntu-certified laptop (here), I did not=
think twice if buying it and thought that there would hardly be an audio p=
roblem - I've used Lenovo laptops before and audio worked very well.

However, I was disappointed. Not only had I to use wired Internet=
, as wi-fi does not work without installation of proprietary drivers, not o=
nly had I to install a later kernel, as video card was freezing the system,=
but Linux Audio does not work well at all.

I am using Xubuntu 12.04 with kernel 3.8 now.=
Here's what has already been done.1. All real-time priorities and audio group and such standard stuff set u=
p, checked and rechecked by myself and other people at LAC.

2. Autostatic was kind enough to help me turn off bluetooth and =
webcam, which did seem to help a little bit. His tutorial on this is here.

However, my problems persist.There=
are two distinct problems.Problem 1. Xruns.<=
br>Even if nothing is done on the computer and/or with audio, xr=
uns are generated. For instance, since I started writing this letter, JACK =
was on and right now I have an indicator of xruns in qjackctl which says: 7=
(13). Note, no audio programs are open at all. If I do nothing, just turn o=
n JACK and leave laptop running, xruns are also generated.
Try disabling wifi in th=
e BIOS/UEFI during boot. This can have dramatic results.=
