audio problems after upgrade to 14.1

Can anyone help me with my sound issue?

I'm experiencing a situation that’s similar to what’s been described in this thread.

However, I won’t be ‘reinstalling Linux’ since I’m accustomed to having it on other computers and using a virtual machine for different purposes. ;-)

Recently, I’ve been experiencing sound problems since upgrading from version 14.0 to 14.1 last month.

Today, I set aside some time to try to resolve the issue and, if possible, pinpoint the root cause.

Here’s what’s happening: after a while of using my system, the sound cuts out.

I usually restart the audio daemon (sndiod) or sometimes reboot, which has typically worked to restore sound.

However, for some unknown reason, since last month, this approach has stopped being effective.

I’m starting to suspect it might be a hardware issue, as it worked fine for a time after the 14.1 upgrade. The frequency of the sound loss increased months ago in 14.0, prompting me to upgrade in hopes of fixing the issue.

What do you recommend? Reinstalling FreeBSD is tempting and seems like it could be a quick fix, but that might be overkill.

I've never reinstalled FreeBSD; I’ve only removed all packages once as an option. I’ve been using this PC since 2022 and have transferred data from other systems, but I've never gone through a complete reinstallation.
My version is:
Code: 
FreeBSD bside 14.1-RELEASE-p5 FreeBSD 14.1-RELEASE-p5 GENERIC amd64

I've executed all steps above in the thread (in the past, before upgrade from 14.0 to 14.1) I've solved with them but now, it is not working anymore.

Now:

Note: cat /dev/random to /dev/dsp0 or /dev/dsp1 doesn't not play any noise sound despite of my volume is at 100% on both

Code: 
$ mixer -a
pcm0:mixer: <Intel Jasper Lake (HDMI/DP 8ch)> on hdaa0 (play)
    vol       = 1.00:1.00     pbk
    pcm       = 1.00:1.00     pbk
pcm1:mixer: <KTMicro KT USB Audio> on uaudio0 (play) (default)
    vol       = 1.00:1.00     pbk
    pcm       = 1.00:1.00     pbk

Code: 
$ cat /dev/random > /dev/dsp0
^C

$ cat /dev/random > /dev/dsp1
cat: stdout: Invalid argument


TIA

Reinstalling won't fix it. The kernel is hard to mess up.

Just get a USB sound thingie.

Thanks, but I don't think it's necessary to reinstall (that can often lead to more issues).

I managed to fix my problem yesterday. It seemed that the chipset (not entirely sure) kept the mute setting that was applied when I booted into Windows for my yearly update (I still have the original OEM installation on another SSD). I had muted the sound, and it stayed muted.

I decided to boot back into Windows to check if it was a hardware issue and noticed the sound was indeed muted there. I turned it on, booted back into FreeBSD, and the problem was gone.

Now, I’m curious to find out what setting Windows changed. There are a lot of keys in /dev/sndstat (as detailed in the thread).

(P.S. I admit, my solution feels a bit silly... but it worked! :-S)
