refactor: unified multi-profile build system

Add 4 configurable profiles (stable-cinnamon, stable-niri, mainline-cinnamon, mainline-niri) with a single unified build entry point. - iso/build.sh: replaces build-iso.sh / build-live-iso.sh / build-niri-live-iso.sh; accepts --profile and --type flags - iso/_inner-build-unified.sh: replaces the three _inner-build-*.sh scripts; branches on BUILD_TYPE / DESKTOP / KERNEL_PKG env vars - config/profiles/stable-niri/: new — linux (k6) + niri/Wayland/noctalia - config/profiles/mainline-cinnamon/: new — linux-mainline (k7) + Cinnamon/X11 - config/profiles/mainline-niri/packages.live.list: symlink added - config/profiles/stable-cinnamon/packages.live.list: symlink added - Makefile: PROFILE variable (default stable-cinnamon), shellcheck updated - installer/install.sh: respects DEFAULT_PROFILE env (set by live ISO) - tests/run-qemu-test.sh: passes PROFILE through to build and overlay Live ISOs embed the installer pre-configured for the same profile they were built with (DEFAULT_PROFILE in /etc/profile.d/).
Add kernel-7 audio diagnostics and verify SOF/UCM completeness

+# Kernel 7 Audio Troubleshooting for Dell XPS 17 9700
+
+## Symptom
+On the Niri live ISO booting kernel 7, audio shows only HDMI devices and "Dummy Output" in `wpctl status`. Internal speakers and headphone jack do not appear.
+
+## Root Cause
+The XPS 17 9700 is a Dell SoundWire platform requiring **SOF + SoundWire** for internal audio on modern Linux kernels. The issue is **not** PipeWire misconfiguration. Common causes are:
+
+1. Kernel driver stack selection issue (wrong path selected at boot)
+2. Missing or mismatched SOF firmware/topology
+3. Missing or mismatched `sof-soundwire` UCM profiles
+4. A kernel SoundWire regression
+
+## Diagnostic Steps
+
+### 1. Verify the driver stack is loading
+Boot into the live ISO and check which driver is active:
+
+```bash
+# Should show SOF driver for internal audio
+lsmod | grep -E '^sof|^snd_sof'
+
+# Should show the SoundWire machine driver
+lsmod | grep -E 'sof_sdw|sof.*mach'
+
+# Check kernel logs for SoundWire errors
+sudo dmesg | grep -Ei 'soundwire|sdw|sof.*error|topology.*-22'
+```
+
+### 2. Test explicit SOF driver selection
+If internal audio is missing, the kernel's auto-detection may have selected the wrong path. At the GRUB/boot menu, edit the kernel command line and add:
+
+```
+snd-intel-dspcfg.dsp_driver=3
+```
+
+This explicitly forces SOF (value `3`) for the audio stack. Options are:
+- `0`: auto (kernel's default)
+- `1`: legacy HDA
+- `3`: SOF (correct for this laptop)
+- `4`: AVS
+
+Then boot and re-check:
+```bash
+wpctl status
+```
+
+### 3. Verify package completeness
+Ensure the live image has the required audio support packages:
+
+```bash
+xbps-query -l | grep -E '^ii.*sof-firmware|alsa-ucm-conf|alsa-utils'
+```
+
+Expected output should include:
+- `sof-firmware` (Sound Open Firmware binaries and topology)
+- `alsa-ucm-conf` (Use Case Manager profiles for `sof-soundwire`)
+- `alsa-utils` (ALSA utilities and initial mixer state)
+
+### 4. Check PipeWire/WirePlumber state
+Once the kernel exposes the internal audio devices (they should appear in `wpctl status`), verify PipeWire is reading them correctly:
+
+```bash
+# List all devices seen by PipeWire
+pw-cli ls Device
+
+# Check WirePlumber's ALSA monitor for errors
+journalctl -u wireplumber.service -n 50
+
+# Manually re-scan if needed
+pw-cli list-objects Module | grep monitor
+```
+
+## If It Still Fails
+
+### Check for a kernel regression
+Recent kernel versions 6.9 and 6.10 had SoundWire regressions affecting XPS-series Dell laptops. These were fixed in:
+- 6.9.x (fixed in 6.9 stable releases)
+- 6.10.11+
+
+If kernel 7.x shows the same symptoms, check the [SOF upstream issues](https://github.com/thesofproject/linux/issues) for similar reports.
+
+### Compare against a known-good kernel
+If kernel 7 still fails with `dsp_driver=3`:
+1. Boot with the fallback kernel 6 (available in the Niri live ISO GRUB menu)
+2. Test audio on kernel 6
+3. If audio works on kernel 6 but not kernel 7, there is likely a kernel-7-specific regression
+
+Report findings to:
+- [SOF upstream](https://github.com/thesofproject/linux/issues)
+- [Void Linux](https://github.com/void-linux/void-packages)
+
+### Manual ALSA routing (for microphone issues)
+If speakers work but the internal microphone does not, manually set the mic input mux:
+
+```bash
+amixer --card 1 set 'rt715 ADC 24 Mux' 'DMIC3'
+```
+
+Then persist the state:
+```bash
+sudo alsactl store
+```

+## Live ISO Packages
+
+The mainline-niri Niri live ISO includes:
+- `sof-firmware`: Intel SOF binary and topology files
+- `alsa-ucm-conf`: ALSA Use Case Manager profiles, including `sof-soundwire`
+- `pipewire` and `wireplumber`: Session and policy management
+- `linux-mainline`: Kernel 7.x with SOF support
+- `linux`: Kernel 6.x fallback entry in GRUB
+
+The build ensures both kernels are available to test audio driver behavior across kernel versions.

Author	SHA1	Message	Date
Giancarmine Salucci	56dfe11039	refactor: unified multi-profile build system Add 4 configurable profiles (stable-cinnamon, stable-niri, mainline-cinnamon, mainline-niri) with a single unified build entry point. - iso/build.sh: replaces build-iso.sh / build-live-iso.sh / build-niri-live-iso.sh; accepts --profile and --type flags - iso/_inner-build-unified.sh: replaces the three _inner-build-*.sh scripts; branches on BUILD_TYPE / DESKTOP / KERNEL_PKG env vars - config/profiles/stable-niri/: new — linux (k6) + niri/Wayland/noctalia - config/profiles/mainline-cinnamon/: new — linux-mainline (k7) + Cinnamon/X11 - config/profiles/mainline-niri/packages.live.list: symlink added - config/profiles/stable-cinnamon/packages.live.list: symlink added - Makefile: PROFILE variable (default stable-cinnamon), shellcheck updated - installer/install.sh: respects DEFAULT_PROFILE env (set by live ISO) - tests/run-qemu-test.sh: passes PROFILE through to build and overlay Live ISOs embed the installer pre-configured for the same profile they were built with (DEFAULT_PROFILE in /etc/profile.d/).	2026-04-26 12:42:11 +02:00
mozempk	88797bb1e9	Add kernel-7 audio diagnostics and verify SOF/UCM completeness - Add alsa-ucm-conf to installed packages.list (already in live-desktop.list) - Create KERNEL7_AUDIO_XPS9700.md with comprehensive audio diagnostics guide - Document kernel parameter choices and SOF/SoundWire fix approach in build scripts - Includes boot-time dsp_driver=3 test procedure for XPS 9700 kernel 7 compatibility	2026-04-25 22:35:46 +02:00
mozempk	2dc1881b69	Fix niri live ISO audio and dark theme setup	2026-04-25 22:22:07 +02:00
mozempk	21de42b6b1	feat(niri-live): dual-kernel boot menu, audio fix, elogind fix, rsync optimization - Add kernel 7 (linux-mainline) as primary boot entry - Add kernel 6 (linux) as secondary fallback boot entry - Simplified boot menu: single entry per kernel, no failsafe variants - Add snd-intel-dspcfg.dsp_driver=1 + snd_hda_intel.dmic_detect=0 to BOOT_CMDLINE - Fix elogind sv: dual D-Bus + PID check to suppress already-running warnings - Replace cp -rfpPv with rsync -aHX in copy_include_directories (nixpkgs speed fix) - Fix trailing slash bash glob bug in mklive.sh and postsetup-nvidia.sh - Add -v linux-mainline to _inner-build-niri-live.sh for correct primary kernel	2026-04-25 21:38:07 +02:00
mozempk	6bb29fc081	fix(mainline-niri): add linux-mainline-headers to enable nvidia DKMS on kernel 7.0	2026-04-25 20:15:43 +02:00
mozempk	cd8248f2f5	feat: NVIDIA PRIME, audio fix, timezone, dmesg error cleanup - Add nvidia/nvidia-dkms/nvidia-libs-32bit/nvidia-vaapi-driver to niri live and installed profiles; wireless-regdb and sof-firmware to all profiles (fixes regulatory.db and SOF firmware dmesg errors) - iso/postsetup-nvidia.sh: new mklive -x hook that re-runs dracut inside the rootfs chroot after the overlay is applied; ensures the squashfs initramfs includes nvidia.ko and omits nouveau.ko at build time — no driver install needed at runtime (fixes /run tmpfs overflow that was killing wireplumber by corrupting D-Bus sockets) - Both ISO inner build scripts gain -x postsetup-nvidia.sh and the nonfree repo flag so nvidia packages resolve correctly - niri config: wireplumber started via supervisor loop (waits for PipeWire socket, auto-restarts on crash) replacing the one-shot exec — survives any D-Bus or pipewire disruption - build-niri-live-iso.sh: NVIDIA modprobe blacklist-nouveau.conf, btusb-quirks.conf, modules-load.d/nvidia.conf, dracut/10-nvidia.conf, Xorg intel/nvidia configs, prime-run helper, elogind run script loop guard, timezone Europe/Zurich overlay, updated BOOT_CMDLINE - build-live-iso.sh: same NVIDIA + timezone + sound udev rule overlays; live-setup.sh timezone and audio group fix - installer/lib/grub.sh: GRUB_CMDLINE_LINUX_DEFAULT gains nvidia-drm.modeset=1 rd.driver.blacklist=nouveau btusb.enable_autosuspend=0 - installer/lib/postinstall.sh: configure_nvidia_prime() adds blacklist-nouveau.conf, btusb-quirks.conf, dracut omit_drivers nouveau, modules-load.d with all four nvidia modules	2026-04-25 18:27:06 +02:00
