I’ve installed Guix System on a Dell Pro 13 Premium PA13250 with an Intel Core Ultra 5 236V [Lunar Lake CPU](https://en.wikipedia.org/wiki/Lunar_Lake). And everything seems fine so far… except the laptop speaker audio and headphone jack audio don’t work. At least after adding `(service bluetooth-service-type)` to my system config, I got bluetooth audio working! But I’d like my laptop speakers to work… OK, so I [added nonguix](https://gitlab.com/nonguix/nonguix) to my `~/.config/guix/channels.scm` file. And in my system configuration, I have this. ```auto (use-modules (gnu) (nongnu packages linux)) (operating-system (kernel linux) (firmware (list linux-firmware sof-firmware)) ;; ... ``` I didn’t have `sof-firmware` in my `firmware` list at first, but I noticed there were some error messages in `dmesg` about it missing. (Sorry, I should have saved the exact error.) Anyway, after adding `sof-firmware`, `dmesg` seems happy. ```auto $ sudo dmesg | grep -i -E 'sof-|codec|snd' [6.210070] snd_hda_intel 0000:00:1f.3: SoundWire enabled on CannonLake+ platform, using SOF driver [7.512689] sof-audio-pci-intel-lnl 0000:00:1f.3: enabling device (0000 -> 0002) [7.512777] sof-audio-pci-intel-lnl 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if 0x040380 [7.513032] sof-audio-pci-intel-lnl 0000:00:1f.3: bound 0000:00:02.0 (ops intel_audio_component_bind_ops [xe]) [7.520110] sof-audio-pci-intel-lnl 0000:00:1f.3: use msi interrupt mode [7.542503] sof-audio-pci-intel-lnl 0000:00:1f.3: hda codecs found, mask 4 [7.542507] sof-audio-pci-intel-lnl 0000:00:1f.3: NHLT device BT(0) detected, ssp_mask 0x4 [7.542508] sof-audio-pci-intel-lnl 0000:00:1f.3: BT link detected in NHLT tables: 0x4 [7.542510] sof-audio-pci-intel-lnl 0000:00:1f.3: DMICs detected in NHLT tables: 0 [7.548173] sof-audio-pci-intel-lnl 0000:00:1f.3: Firmware paths/files for ipc type 1: [7.548181] sof-audio-pci-intel-lnl 0000:00:1f.3: Firmware file: intel/sof-ipc4/lnl/sof-lnl.ri [7.548182] sof-audio-pci-intel-lnl 0000:00:1f.3: Firmware lib path: intel/sof-ipc4-lib/lnl [7.548182] sof-audio-pci-intel-lnl 0000:00:1f.3: Topology file: intel/sof-ipc4-tplg/sof-lnl-cs42l43-l0.tplg [7.548959] sof-audio-pci-intel-lnl 0000:00:1f.3: Loaded firmware library: ADSPFW, version: 2.13.0.1 [7.795503] sof-audio-pci-intel-lnl 0000:00:1f.3: Booted firmware version: 2.13.0.1 [8.485300] cs42l43-codec cs42l43-codec: supply vdd-amp not found, using dummy regulator [8.520007] sof-audio-pci-intel-lnl 0000:00:1f.3: Topology: ABI 3:29:1 Kernel ABI 3:23:1 [8.522655] sof-audio-pci-intel-lnl 0000:00:1f.3: Loaded firmware library: ADSPFW, version: 2.13.0.1 [15.581822] input: sof-soundwire Jack as /devices/pci0000:00/0000:00:1f.3/sof_sdw/sound/card0/input20 [15.582157] input: sof-soundwire HDMI/DP,pcm=5 as /devices/pci0000:00/0000:00:1f.3/sof_sdw/sound/card0/input21 [15.582237] input: sof-soundwire HDMI/DP,pcm=6 as /devices/pci0000:00/0000:00:1f.3/sof_sdw/sound/card0/input22 [15.582312] input: sof-soundwire HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:1f.3/sof_sdw/sound/card0/input23 ``` However, I still have no speaker audio. ☹ `aplay` seems to see my device… ```auto $ guix shell alsa-utils -- aplay -l ****List of PLAYBACK Hardware Devices**** card 0: sofsoundwire [sof-soundwire], device 0: Jack Out (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofsoundwire [sof-soundwire], device 2: Speaker (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofsoundwire [sof-soundwire], device 5: HDMI1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofsoundwire [sof-soundwire], device 6: HDMI2 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofsoundwire [sof-soundwire], device 7: HDMI3 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofsoundwire [sof-soundwire], device 31: Deepbuffer Jack Out (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 ``` I tried running [`speaker-test`](https://linux.die.net/man/1/speaker-test), but I couldn’t hear anything. ```auto $ guix shell alsa-utils -- speaker-test -D hw:0,2 -c 2 speaker-test 1.2.11 Playback device is hw:0,2 Stream parameters are 48000Hz, S16_LE, 2 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 192 to 1048576 Period size range from 48 to 524288 Periods = 4 was set period_size = 12000 was set buffer_size = 48000 0 - Front Left 1 - Front Right ``` I think `speaker-test` uses ALSA directly, so I think(?) I’m bypassing Pulse/Pipewire… which I’m guessing means the issue isn’t with Pulse or Pipewire… More info: ```auto $ sudo lspci | grep -i audio 00:1f.3 Audio device: Intel Corporation Lunar Lake-M HD Audio Controller (rev 10) $ sudo dmesg | grep -i codec [7.542503] sof-audio-pci-intel-lnl 0000:00:1f.3: hda codecs found, mask 4 [8.485300] cs42l43-codec cs42l43-codec: supply vdd-amp not found, using dummy regulator ``` ---

This GitLab issue seems related: [Kernel support for latest Lunar Lake platforms audio (#390) · Issues · Nonguix / nonguix · GitLab](https://gitlab.com/nonguix/nonguix/-/issues/390) But the change got reverted because it was breaking `aarch64` builds. 😢 I tried adding this patch to my `system.scm` file. (Takes a while to build…) ```diff diff --git a/system.scm b/system.scm index c76663e..eb9f8cc 100644 --- a/system.scm +++ b/system.scm @@ -12,13 +12,20 @@ (btv tailscale) (gnu packages cups) (gnu packages fonts) + (gnu packages linux) (nongnu packages linux) (nongnu system linux-initrd)) +(define-public linux-custom + (customize-linux #:linux linux + #:configs + '("CONFIG_SND_SOC_INTEL_USER_FRIENDLY_LONG_NAMES=y" + "CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH=m"))) + (use-service-modules cups desktop networking ssh xorg) (operating-system - (kernel linux) + (kernel linux-custom) (initrd microcode-initrd) (firmware (list linux-firmware sof-firmware)) (locale "en_US.utf8") ``` I also checked the kernel build-time config using this command. It seems to show the configuration was applied. ```auto $ zcat /proc/config.gz | grep -E 'USER_FRIENDLY_LONG_NAMES|SOUNDWIRE_SOF_MACH' CONFIG_SND_SOC_INTEL_USER_FRIENDLY_LONG_NAMES=y CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH=m ``` But still no speaker audio. 😭 ---

@wegei8 Hey I’m sorry for necro-ing this thread but I was wondering if you were ever able to get the audio working? If so, how? I have a similar device a Dell 13 XPS (2024) also with intel core and lunar lake and I have the exact same issues with the audio not working despite sof-firmware being specified in the config.scm 🫠 any help would be greatly appreciated 🙏
