Hello all, Now I try to transit linux 3.x. But I have a problem on alsa. When I use 3.x, get crack noise on my USB audio randomly. I tested with 3.0rc, 3.1rc, 3.1.4 and 3.2.5. However all 3.x kernels has this problem. (2.6.x works well.) My USB audio is Yamaha SE-U33 recognized as "Philips (or NXP) Digital Speaker System" on lsusb. I tried to tune settings; * use dmix and tune buffers * load snd-usb-audio with nrpacks option (1,10,20) * compile kernel with preempt option * change kernel timer frequency (250, 300, 1000) * trun kernel options off; "USB runtime power management" and "Dynamic USB minor allocation". But nothing changed! How do I do next to fix this problem? -- Tatsuki Sugiura mailto:sugi@xxxxxxxxx ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
