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 for the report. To be sure the issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression tracking bot:
#regzbot ^introduced v6.0..v6.1 #regzbot title alsa: usb: audio stopped working #regzbot ignore-activity
This isn't a regression? This issue or a fix for it are already discussed somewhere else? It was fixed already? You want to clarify when the regression started to happen? Or point out I got the title or something else totally wrong? Then just reply and tell me -- ideally while also telling regzbot about it, as explained by the page listed in the footer of this mail.
Reminder for developers: When fixing the issue, add 'Link:' tags pointing to the report (see page linked in footer for details).
