Introduce the generic, target-agnostic pieces for a gadget-driven USB Audio Class DAC, gated by the HAVE_HOST_USB_AUDIO target flag so they stay inert unless a target opts in. Rather than adding a new USB mode, reuse the existing usb_audio setting (never / always / while charge-only / while mass-storage) with its LANG_USB_DAC string, usb_set_audio() callback and the PCM_MIXER_CHAN_USBAUDIO mixer channel. HAVE_HOST_USB_AUDIO becomes the umbrella capability flag for this common code; USB_ENABLE_AUDIO stays the native usbstack class-driver contract (which needs HAVE_USBSTACK and so cannot be used by hosted ports whose kernel owns the USB controller). usb_set_audio() is declared here and implemented by the target (natively by the usbstack driver, or in the hosted port for gadget targets, as with usb_audio_get_active()), and applied at settings load. The playback interlock in wps.c/playback.c keeps local playback from mixing with host audio while the DAC is active. Simulator stubs for usb_set_audio() and usb_audio_get_active() keep sim builds linking. Co-Authored-By: Claude Opus 4.8 Change-Id: I5b7738508c24721d91d4c32379102a1ac7c6228b |

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
