afr_configure() returned 1 for every message. For DSP_PROC_NEW_FORMAT that is PROC_NEW_FORMAT_DEACTIVATED, so the DSP did not call the stage for the buffer that brought a new format: the first buffer of each track went out unfiltered, and the filters started on the second. That is 128 samples of a WAV file, and the whole first block of a codec with 32-bit non-interleaved output, 4608 samples of a FLAC file. A codec sets the format again at the start of every track, so between gapless tracks this put a short stretch of unfiltered audio into filtered audio, heard as a click at the join. Return 0, as the other stages do. Found with test_codec's DSP checksums on a Sansa Clip+: a model of the DSP with fatigue reduction left out of each file's first buffer reproduces the sixteen checksums of two runs, and none of them with it left in. Listening on the same player, the click between gapless tracks is gone with this change. Change-Id: I7a1193fa0a4ee0c983cbcc5c1af201e1678579d0 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

Build Your Own Rockbox
1. Clone 'rockbox' from git (or extract a downloaded archive).
$ git clone git://git.rockbox.org/rockbox
or
$ tar xJf rockbox.tar.xz
2. Create a build directory, preferably in the same directory as the firmware/
and apps/ directories. This is where all generated files will be written.
$ cd rockbox
$ mkdir build
$ cd build
3. Make sure you have mips/m68k/arm-elf-gcc and siblings in the PATH. Make sure
that you have 'perl' in your PATH too. Your gcc cross compiler needs to be
a particular version depending on what player you are compiling for. These
can be generated using the rockboxdev.sh script in the /tools/ folder of the
source.
$ which arm-elf-eabi-gcc
$ which perl
4. In your build directory, run the 'tools/configure' script and enter what
target you want to build for and if you want a debug version or not (and a
few more questions). It'll prompt you. The debug version is for making a
gdb version out of it. It is only useful if you run gdb towards your target
Archos.
$ ../tools/configure
5. *ploink*. Now you have got a Makefile generated for you.
6. Run 'make' and soon the necessary pieces from the firmware and the apps
directories have been compiled, linked and scrambled for you.
$ make
$ make zip
7. unzip the rockbox.zip on your music player, reboot it and
*smile*.
If you want to build for more than one target, just create several build
directories and create a setup for each target:
$ mkdir build-fuzeplus
$ cd build-fuzeplus
$ ../tools/configure
$ mkdir build-xduoox3
$ cd build-xduoox3
$ ../tools/configure
