Taking after csita I unplugged/replugged all my external audio devices and restarted pulseaudio and alsa-mixer. I found the below error in journalctl:
Jun 27 09:15:37 hostname pulseaudio[3735]: Failed to load module "module-alsa-card" (argument: "device_id="2" name="usb-N-SIA_KJ- USB_HEASET-00" card_name="alsa_card.usb-N-SIA_KJ-USB_HEASET-00" 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. This is a usb headset. When unplugging and leaving unplugged after reboot everything works. The failure to load the the module for the USB headset was for some reason leaving pulseaudio blocked on IO in a D state. I use audio via HDMI output from my Nvidia card. I have Nvidia driver 440 installed on my system, but I do not use the Nvidia driver. I still use nouveau. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1880835 Title: pulse audio hangs in kernel call To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1880835/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
