* Regression in kernel 3.19-rc5 for usb2 scarlett 18i20 @ 2015-01-25 11:42 Guido Aulisi 2015-01-26 13:04 ` Takashi Iwai 0 siblings, 1 reply; 6+ messages in thread From: Guido Aulisi @ 2015-01-25 11:42 UTC (permalink / raw) To: alsa-devel Hi, I noticed a regression in 3.19-rc5 kernel (as shipped by fedora rawhide) with usb2 focusrite scarlett 18i20. I get a lot of xruns with jack, even at 1024 frame buffer and 2 periods. In 3.17.8 it works quite well without xruns at the same settings. I use a fedora 20 (64bit) laptop with 8GB ram, I only installed the rawhide kernel to try the new included scarlett mixer, no other software components changed. I can try to do some other test, but compiling the kernel on this laptop is time consuming. Thanks Guido ^ permalink raw reply [flat|nested] 6+ messages in thread

Chris, do you have any clue? In anyway, Guido, could you give lsusb -v output (for the relevant part)? thanks, Takashi ^ permalink raw reply [flat|nested] 6+ messages in thread

IMHO I think this is something about usb than the mixer, because I didn't use it, I only noticed the xruns even without playing audio. I didn't try 3.18, because it isn't shipped with fedora yet.

I compiled it myself using fedora config from http://pkgs.fedoraproject.org/cgit/kernel.git/ Also the mixer is present and I could switch headphones on and off (great thing). I still have to understand most of the controls... Thank you for the support. If I have some time the next days, I'll try to bisect from rc5 to rc6, to see if some commit fixed this issue, or if more probably I did something wrong.
