Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
46f5710f0b
The device reports Synch: Synchronous on the playback interface. This causes regular audible napping on sample rates that are not multiples of 1 kHz. Fix to Synch: Asynchronous. Specifically observed on Focusrite Scarlett Solo 2nd generation. I assume the first generation model has a different device ID. A first generation Scarlett 2i2 I was able to test advertised Synch: Asynchronous by default. For example, with a sample rate of 44100 Hz, a silent sample is played every 40.96 seconds (likely 44.0 samples instead of 44.1 transmitted per USB frame on average, 4096 being the size of some internal buffer). There may be some other bug at play here since this doesn't happen on other platforms. However, a feedback endpoint is listed and using it fixes the issue. That is the only change in the quirk, but I didn't find a way to declare only it. Tested on two units and on two different computers.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
