[SOLVED] USB audio interface problems since kernel 6.12.113

Anyone having problems with their audio interface lately? I use a Behringer UMC204HD and since I removed 6.12.111 it stopped working. Could this just be an issue with the Behringer?

Re: [SOLVED] USB audio interface problems since kernel 6.12.113

Are you saying it works with the old kernel but not with the new kernel? What's the output of aplay -l and are the cards in the same order with both kernels? Are you using any sound server like pulseaudio,pipewire or jackd or do you just use some alsa config file to select the device?

I only have usb headphones to test with, and they're still working with 6.12.115.

Yeah. I had to go back to 6.12.111 for it to work. aplay -l shows the device. I'm using jackd and it just doesn't want to work, so I installed pulseaudio and it doesn't work with that either. It's not the interface as I've tested it on the raspberry pi5 6.18.55, cachyOS 7.3.1 and fedora 7.2.12. They all worked.

What errors or other messages do you see in syslog when you connect this USB audio device?

run this before inserting the device:

sudo tail -f /var/log/syslog

Also try to see with alsamixer in a terminal (F6 to select the device) that the outputs aren't muted

Give the new 116 version a try, I seen it mention something about usb audio fix in the change log as I was scrolling by.

Where did you see the changelog of the debian 6.12.116 kernel?

apt is telling me: "Changelog unavailable for linux-signed-amd64=6.12.116+1 (404  Not Found)"

and if I look in the http folder where apt tries to get it from I only see the changelog up to 6.12.113:
http://metadata.ftp-master.debian.org/c … 4/?C=M;O=D

Or do you mean the upstream changelog?

The wonderful little program apt-listchanges shows change logs, this was not a large one like usual lately for hundreds of CVE's seemingly. But that is where I seen it with the dozens of other programs that were updated today. I see the stupid cannot download change log errors all of the time too. Oh if you install it and actually want to see the change logs change the config so it shows it and not just the news file for some strange reason it defaults to only showing you the news files. Oh, you may want to blank the email setting too to stop the GD spamming it does sending you emails all of the time.

root@9600k:~# cat /etc/apt/listchanges.conf
[apt]
frontend=pager
which=both
email_address=
email_format=text
confirm=false
headers=false
reverse=false
save_seen=/var/lib/apt/listchanges

Upgrading to 6.12.116 fixed it.

@RedGreen925 Thanks for the info regarding apt-listchanges!

With regards to the problem of the OP I guess you meant the following changelog entry from 6.12.116:

* ALSA: usb-audio: Use the right limit for PCM OOB check (Closes: #1152888)

It certainly sounds like it could have something to do with the OPs problem.

Yes that is what I seen and thought I would mention it in this thread, good to see it sorted it for him. My USB audio interface just continued to work as usual during all of this.
