%description
Restores stereo internal speakers on the ASUS ProArt PX13 (HN7306, AMD
Strix Halo / SoundWire TAS2783) under Fedora on stock kernels >= 7.1.

The stock kernel driver initializes both speaker amplifiers on the same
DSP channel, and the machine driver does not tag the ALSA card with
spk:tas2783, so PipeWire never exposes a speaker sink. This package
installs:

- a PX13-specific snd-soc-tas2783-sdw DKMS module (channel-selection
  control, rebuilds on every kernel update)
- ALSA UCM files plus a SKU-probed long-name override
- a oneshot service that writes the override for this machine's DMI
  card name

Fedora-specific change: the DKMS module is built with GCC (Fedora's
kernel toolchain). Building with LLVM/Clang fails against a GCC-built
kernel.

Based on https://github.com/ftoleedo/px13-audio-fix
(%{upstream_commit})
Packaged for Fedora by devcoons.

Secure Boot must be disabled, or the DKMS module must be signed and
enrolled, or the module will not load.

A reboot is required after the first install so the patched module can
replace the in-use stock codec.

%package resume
Summary:        Optional s2idle SoundWire resume recovery for ASUS ProArt PX13
Requires:       %{name} = %{version}-%{release}

%description resume
Optional systemd-sleep hook that recovers ASUS ProArt PX13 internal
speakers after s2idle. The TAS2783 DSP firmware and SoundWire slaves
can fail to come back after suspend even when mixer levels look fine.

Do not install this subpackage unless speakers actually stop working
after resume. Test boot -> speakers -> suspend -> resume first.
