I installed the kernel by adding deb http://archive.ubuntu.com/ubuntu/ eoan-proposed restricted main multiverse universe to my /etc/apt/sources.list
and then installed sudo apt-get install linux-image-5.3.0-28-generic and sudo apt-get install linux-image-5.3.0-28-lowlatency The 5.3.0-28-lowlatency kernel has the same behaviour as 5.3.0-26-lowlatency, i.e. recognizing the cards but not the pcm device. $ uname -a Linux sim00448 5.3.0-28-lowlatency #30-Ubuntu SMP PREEMPT Wed Jan 15 02:18:14 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux The generic kernel did not load any snd modules when checked with "$ lsmod | grep snd". $ uname -a Linux sim00448 5.3.0-28-generic #30-Ubuntu SMP Wed Jan 15 01:08:19 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux $ ls -l /proc/asound ls: cannot access '/proc/asound': No such file or directory $ dmesg | grep -i audio [ 0.138934] ACPI: Added _OSI(Linux-Lenovo-NV-HDMI-Audio) [ 0.809235] usb 3-3: Manufacturer: M-Audio [ 1.392886] input: M-Audio Fast Track C400 as /devices/pci0000:00/0000:00:14.0/usb3/3-3/3-3:1.5/0003:0763:2030.0001/input/input2 [ 1.451099] hid-generic 0003:0763:2030.0001: input,hidraw0: USB HID v1.10 Keyboard [M-Audio Fast Track C400] on usb-0000:00:14.0-3/input5 $ aplay -l aplay: device_list:272: no soundcards found... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859781 Title: snd_usb_audio not working in 5.3.0-26-lowlatency To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1859781/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
