System error on startup

bn flag

I have a new Ubuntu install (22.04.2) on a Lenovo ThinkPad T460. It's actually set up as dual-boot with Windows 10. I'm using the XFCE desktop with lightdm as the display manager.

When it boots, I get a small dialog box that says "System Program Problem Detected". If I click on "Report problem", nothing seems to happen. If I click on either button the system seems to run normally.

/var/crash is empty

If I choose System -> Logs from the XFCE menus, the only "Important" log that I see is:

Other Error opening PCM device front:0: No such file or directory

A check in syslog shows this message as being generated by pulseaudio at startup. I sort of assumed that the PCM device was a sound problem, but system sounds play normally. (and I still don't know if that's what's causing the dialog :-). The only place the "front:0" string ever shows up is in the output of pactl:

pactl list | egrep "^Source|^Sink|device.string"
Sink #0
                device.string = "front:0"
Source #0
                device.string = "0"
Source #1
                device.string = "front:0"
                device.string = "0"

Where can I look for more detail on this? Any other way to find the cause of the "System Program ..." dialog?

Thanks!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
