After today's update of linux-*-5.19.0-35-generic:amd64 I see many entries in syslog like these:

Mar  2 12:04:57 xxx kernel: [ 4646.030116] snd_hda_intel 0000:00:1f.3: Too many BDL entries: buffer=2097152, period=65536
Mar  2 12:04:57 xxx kernel: [ 4646.031191] snd_hda_intel 0000:00:1f.3: Too many BDL entries: buffer=1048576, period=32768
Mar  2 12:04:57 xxx kernel: [ 4646.032330] snd_hda_intel 0000:00:1f.3: Too many BDL entries: buffer=2097152, period=65536
Mar  2 12:04:57 xxx kernel: [ 4646.033556] snd_hda_intel 0000:00:1f.3: Too many BDL entries: buffer=1048576, period=32768
Mar  2 12:04:57 xxx kernel: [ 4646.035347] snd_hda_intel 0000:00:1f.3: Too many BDL entries: buffer=4194304, period=131072

Previous versions of kernels did not produce such error messages: I searched past system logs of more than one year old.

Some information about my Ubuntu 22.10 GNOME (Xorg) notebook computer:

$ uname -rv
5.19.0-35-generic #36-Ubuntu SMP PREEMPT_DYNAMIC Fri Feb 3 18:36:56 UTC 2023

It seems that these messages occur during system boot and during log in (around a hundred messages each time).

Any ideas of the meaning of these messages?

Note: Currently, I do not have any problems with audio.

Update (2023-04-26)

After update to kernel 6.2 (Ubuntu 23.04) these entries ceased to appear.

  • I have exactly the same problem with my MSI GL73 8SD running Ubuntu 22.10. Like you it started after this kernel update. – Laurent Lyaudet Mar 04 '23 at 15:20

    Thanks @LaurentLyaudet ! – FedKad Mar 04 '23 at 17:42
  • Hi! Were you able to find a solution? I have a similar problem and now the audio on my HDMI/Display port is not working. I opened this question about it: https://askubuntu.com/questions/1457893/my-hdmi-display-port-audio-stopped-working-on-ubuntu-22-10 – Fábio Sousa Mar 06 '23 at 12:42

    The same problem with kernel `5.19.0-38-generic` too! :( – FedKad Mar 22 '23 at 18:12
  • Sorry for you. 5.19.0-38 solved the issue for me. Maybe your hardware is slightly different from mine and you should upload some data about it in the launchpad bug report? – Laurent Lyaudet Mar 22 '23 at 20:55
  • Same here wanted to reboot. Gnome never launched and when i did login in terminal mode i got a ton of this error messages. – Arjan Apr 09 '23 at 18:50
  • I had the same errors also folowing yesterdays updates on Ubuntu 22.10 Wayland. ditto - audio seems to still work. However, this problem has dissapeared when I updated to Ubuntu 23.04 – TurnipThrasher Mar 02 '23 at 17:11

Well I have got issues with my sound card Creative Sound Blaster Z with the new kernel 5.19.0-35.

There was no sound and it said 'dummy audio' in settings. I tried some tricks from the internet but nothing helped, so I had to revert back to kernel 5.19.0.32 and everything works ok

  • Thanks for that, I had a similar problem and the audio on my HDMI/DISPLAY port was not working, rolling back the kernel solved my problem. – Fábio Sousa Mar 06 '23 at 13:00

This solved my issue

sudo ubuntu-drivers autoinstall

Faced same issue with new kernel 5.19.0-35. It appears there are some issue with NVidia drives. Above step worked for me.
