Hi, sound was working for years on my Debian System w/o any issue with pulseaudio. Since a few weeks I have problems with the on-board Intel sound, listed as
Device-1: Intel Cannon Lake PCH cAVS driver: snd_hda_intel whereas the Logitech USB headset always works Device-2: Logitech Headset H390 type: USB driver: hid-generic,snd-usb- audio,usbhid Full inxi -F output is here: http://paste.debian.net/1184310/ Out of the blue I noticed today that it worked again, but after I rebooted into Debian 10.8 it disappeared again. In dmesg I find [...] [ 13.567175] snd_hda_intel 0000:00:1f.3: enabling device (0000 -> 0002) [ 13.567306] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 13.609251] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC887-VD: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:line [ 13.609252] snd_hda_codec_realtek hdaudioC0D0: speaker_outs=1 (0x1a/ 0x0/0x0/0x0/0x0) [ 13.609253] snd_hda_codec_realtek hdaudioC0D0: hp_outs=1 (0x1b/ 0x0/0x0/0x0/0x0) [ 13.609253] snd_hda_codec_realtek hdaudioC0D0: mono: mono_out=0x0 [ 13.609254] snd_hda_codec_realtek hdaudioC0D0: dig-out=0x11/0x0 [ 13.609254] snd_hda_codec_realtek hdaudioC0D0: inputs: [ 13.609255] snd_hda_codec_realtek hdaudioC0D0: Rear Mic=0x18 [ 13.609256] snd_hda_codec_realtek hdaudioC0D0: Front Mic=0x19 [ 13.609256] snd_hda_codec_realtek hdaudioC0D0: Line=0x15 [...] http://paste.debian.net/1184308/ In $ pactl list I get Card #0 Name: alsa_card.usb-Logitech_Logitech_USB_Headset-00 Driver: module-alsa-card.c Owner Module: 6 Properties: alsa.card = "1" alsa.card_name = "Logitech USB Headset" alsa.long_card_name = "Logitech Logitech USB Headset at usb-0000:00:14.0-13.1, full speed" alsa.driver_name = "snd_usb_audio" device.bus_path = "pci-0000:00:14.0-usb-0:13.1:1.0" sysfs.path = "/devices/pci0000:00/0000:00:14.0/ usb1/1-13/1-13.1/1-13.1:1.0/sound/card1" udev.id = "usb-Logitech_Logitech_USB_Headset-00" device.bus = "usb" device.vendor.id = "046d" device.vendor.name = "Logitech, Inc." device.product.id = "0a44" device.product.name = "Headset H390" device.serial = "Logitech_Logitech_USB_Headset" device.form_factor = "headset" device.string = "1" device.description = "Headset H390" module-udev-detect.discovered = "1" device.icon_name = "audio-headset-usb" device.intended_roles = "phone" Profiles: input:analog-mono: Analog Mono-Eingabe (sinks: 0, sources: 1, priority: 7, available: yes) output:analog-stereo: Analog Stereo-Ausgabe (sinks: 1, sources: 0, priority: 6500, available: yes) output:analog-stereo+input:analog-mono: Analog Stereo-Ausgabe + Analog Mono-Eingabe (sinks: 1, sources: 1, priority: 6507, available: yes) off: Aus (sinks: 0, sources: 0, priority: 0, available: yes) Active Profile: output:analog-stereo+input:analog-mono Ports: analog-input-mic: Mikrofon (priority: 8700, latency offset: 0 usec) Properties: device.icon_name = "audio-input-microphone" Part of profile(s): input:analog-mono, output:analog- stereo+input:analog-mono analog-output-headphones: Kopfhörer (priority: 9000, latency offset: 0 usec) Properties: device.icon_name = "audio-headphones" Part of profile(s): output:analog-stereo, output:analog-stereo+input:analog-mono http://paste.debian.net/1184312/ but there is no other sound card listed. I tried from the Debian pulseaudio wiki the part under "Missing playback devices or audio capture": rd@h370:~$ rm -r ~/.config/pulse /tmp/pulse-* rm: cannot remove '/home/rd/.config/pulse': No such file or directory rm: descend into write-protected directory '/tmp/pulse-PKdhtXMmr18n'? y rm: remove write-protected directory '/tmp/pulse-PKdhtXMmr18n'? y rm: cannot remove '/tmp/pulse-PKdhtXMmr18n': Operation not permitted rd@h370:~$ ls -ld /tmp/pulse-PKdhtXMmr18n drwx------ 2 root root 4096 Feb 6 20:19 /tmp/pulse-PKdhtXMmr18n rd@h370:~$ systemctl --user restart pulseaudio.service rd@h370:~$ Not sure if it is expected that there is a pulse file for root in /tmp What is also strange for me, is that the intel card is listed by-path by not by-id: rd@h370:~$ ls -l /dev/snd/by-id/ total 0 lrwxrwxrwx 1 root root 12 Feb 6 20:42 usb-Logitech_Logitech_USB_Headset-00 -> ../controlC1 rd@h370:~$ ls -l /dev/snd/by-path/ total 0 lrwxrwxrwx 1 root root 12 Feb 6 20:42 pci-0000:00:14.0-usb-0:13.1:1.0 -> ../ controlC1 lrwxrwxrwx 1 root root 12 Feb 6 20:19 pci-0000:00:1f.3 -> ../controlC0 rd@h370:~$ lspci |grep 00:1f.3 00:1f.3 Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10) rd@h370:~$ Any idea or hint how to debug this issue is welcome.
