[Alsa-user] alsa not seeing sound cards
Kernel 5.0.17 alsa-lib 1.1.9 # aplay -l aplay: device_list:272: no soundcards found... # lspci | grep -i audio 00:1b.0 Audio device: Intel Corporation NM10/ICH7 Family High Definition Audio Controller (rev 02) 02:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1) Any idea why alsa is not seeing these sound cards? Seems to be intermittent. One boot they will be seen and yet a subsequent boot they will not. Happy to provide any other info needed.

It should be automatically detecting it, but the modprobe is a good test.

At least as a debugging step, indeed: # modprobe snd-hda-intel # aplay -l List of PLAYBACK Hardware Devices card 0: Intel [HDA Intel], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: ALC662 rev1 Digital [ALC662 rev1 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 Oh, and there are the nvidia devices also. > It should be automatically detecting it, but the modprobe is a good > test. Agreed. So why not autoloading it all of a sudden?
