I'm currently experiencing a regression with the audio on my Behringer U-Phoria UMC404HD. Alsa info is at: http://alsa-project.org/db/?f=f453b8cd0248fb5fdfa38e1b770e774102f66135 I get no audio in or out for this device with kernel versions 6.1.1 and 6.1.2. The versions I have tried that work correctly include 5.15.86 LTS, 5.19.12, and 6.0.13–16. When I run this on 6.1.1, it will just hang until I ctrl+c: aplay -D plughw:1,0 /usr/share/sounds/alsa/Front_Center.wav I've run strace on that command, and its output is at: https://pastebin.com/WaxJpTMe Nothing out of the ordinary occurs when aplay is run, according to the kernel logs. Please let me know how I can provide additional debugging information if necessary. Thanks Michael
