It seems I have the same problem with two different Logitech webcams. Will test if it is also gone with older kernel. Have test it with Leap 15.2 and webcam Logitech C270: With kernel 5.3.18-lp152.60.1 microphone is mute. With kernel 5.3.18-lp152.57.1 microphone works. Other PC with other Logitech i will test it tomorrow. The problem is kernel 5.3.18-lp152.60.1 A known issue, the fix will be merged in SLE15-SP2/openSUSE-15.2 git branch soon later. Please use my temporary fix kernel (or KOTD later), keep the older kernel or copy the old snd-usb-audio.ko to the new kernel directory as a workaround. *** This bug has been marked as a duplicate of bug 1181014 *** |
After the last kernel update to Linux 5.3.18-lp152.60-preempt #1 SMP PREEMPT Tue Jan 12 23:10:31 UTC 2021 (9898712) the microphone of my USB Webcam (Logitech C270) isn't detected by Pulseaudio anymore. If I boot with the old kernel Linux 5.3.18-lp152.57-preempt #1 SMP PREEMPT Fri Dec 4 07:27:58 UTC 2020 (7be5551) it works again. With the new kernel Pulseaudio shows the following errors: E: [pulseaudio] module-alsa-card.c: Failed to find a working profile. E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="1" name="usb-046d_0825_59DC47E0-02" card_name="alsa_card.usb-046d_0825_59DC47E0-02" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes avoid_resampling=no card_properties="module-udev-detect.discovered=1""): initialization failed. cat /proc/asound/cards outputs the following: 0 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xfce60000 irq 100 1 [U0x46d0x825 ]: USB-Audio - USB Device 0x46d:0x825 USB Device 0x46d:0x825 at usb-0000:2b:00.3-1, high speed 2 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xfc800000 irq 101 3 [J370 ]: USB-Audio - Jabra Link 370 Jabra Link 370 at usb-0000:03:00.0-3, full speed It seems OK. Device 1 is the microphone of the USB cam. All other devices are detected by Pulseaudio.
