I'm affected by what's very likely to be the same issue. This doesn't seem to affect all hardware configurations. My laptop can handle jackd with a latency of 32 samples on my Focusrite Scarlett 2i2 and 3.8.0-25 lowlatency kernel. On my desktop jackd won't even start with a latency of less than 512 samples using the same kernel and same USB audio device.
No help from the proposed 3.8.0-26, so I'll continue using 3.5.x kernels on my desktop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1185563 Title: 3.8.x low latency kernels poor performance with usb To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lowlatency/+bug/1185563/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
