[Kernel-packages] [Bug 1265475] Re: Please apply patches supporting Haswell based Chromebooks
Is there a way someone could turn these into DKMS packages?

[Kernel-packages] [Bug 1136110] Re: USB Audio Codec choppy playback
I thought I should chip in to confirm that I still get occasional issues with my USB DAC, even on the current Saucy 3.11.0-12 kernel. The symptoms are identical to those that were occurring prior to the patch, however now they usually resolve by unplugging and replugging the DAC, whereas prior to the patch they never resolved. I'm thinking there's still something not-quite-right in the kernel handling of these async audio devices. (Or possibly, these async audio devices don't always obey the USB spec perfectly in some way?) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1136110 Title: USB Audio Codec choppy playback Status in “linux” package in Ubuntu: Fix Released Bug description: 1) The release of Ubuntu using Ubuntu 12.10 AMD64.

It's said that such a DAC hosts the clock itself (USB Device Host). An ordinary DAC, so called Synchronous USB DAC, uses the clock hosted by the mother board, which is not affected by this bug. When this bug affects an asynchronous USB DAC, the audio played by the DAC is constantly interrupted. The playback itself does not stop, but the output becomes discontinous, filling with constant crackling noises, destroying everything the DAC plays. Using CLI command grep device.buffering to get the buffer from the devices, those affected kernels are reporting back a different number to the unaffected devices. The choppy noise is very similar to the situation when buffer size is not correctly set. I have tested four USB DACs, two Asynchronous and two Synchronous. Only the Asynchronous ones are affected by this bug.
