[linux-audio-user] zipper noise during playback

[Robert Jonsson]

Hi, 

I think you know this and probably do it right already, can't hurt to repeat 
it though. 
You have to run the sb-live with 48khz sampling frequency to achieve good 
performance. I haven't heard of this particular issue but I imagine it's 
possible since sb-live does internal resampling...
More probable is perhaps that the card is faulty.
