Hi everybody,
I've been using Thinstation (based on Crux) for several years to connect Nano PCs to a Windows Terminal Server in an elementary school.
I recently purchased several nano PCs based on Apollo Lake (Celeron N3350). Everything works fine, except for the analog audio jack connector. Pavucontrol only shows "Dummy output" If I connect a screen via HDMI, the sound works without any problem. Only the jack connector does not work.
Here is my module.list : |module ac97_bus module soundcore module snd module snd-hda-intel module snd-hda-codec module snd-hda-codec-hdmi module snd-soc-core module snd-compress module snd-pcm-dmaengine module snd-soc-acpi-intel-match module snd-soc-acpi module snd-soc-sst-ipc module snd-soc-sst-dsp module snd-intel-dspcfg module snd-hwdep module snd-hda-core module snd-pcm module snd-timer module i915 module x86_pkg_temp_thermal module intel_powerclamp module coretemp module crct10dif-pclmul module i2c-algo-bit module crc32-pclmul module intel-gtt module ttm module crc32c-intel module i2c-i801 module ghash-clmulni-intel module i2c-smbus module lpc_ich module drm_kms_helper module ahci module libahci module cec module libata module joydev module mei-me module drm module igc module scsi_mod module mei module thermal | I removed snd_soc_skl according to https://bkhome.org/news/201912/sound-fix-for-54-kernel-on-apollo-lake.html, without success...
Can you help me ?
Greetings! I have no experience with that exact model but usually Intel chipsets and sound get along reasonably well. What does 'lspci -k' say about the device? Do you see it in 'cat /proc/asound/cards'? Does 'aplay -L' show the expected devices/outputs, including the jack? Do you see anything related in the output of 'dmesg' that might indicate it's missing some firmware binary or throwing any errors? Regards, Matt
