Sound is skipping

[walterbyrd]

I have an old board. It is called a 78LMT-USB3. I have an AMD Phenom II X4 940 3.0 GHz quad-core processors, and 12GB of RAM. I am running FreeBSD 15.0.

My audio: Realtek® ALC892 codec, High Definition Audio, 2/4/5.1/7.1-channel (Note 4), Support for S/PDIF Out

Low end by today's standards, but I used to be able to get video and sound with no problem.

Now, my audio skips. I have googled the problem, but their solutions do not seem to work. Google tells me to do this:

# sysctl hw.snd.latency=7

It does not work at all. I have tried all the other latency settings, nothing works.

Any ideas?

Maybe some progress.
I have tried these two settings:

hw.iommu.enable="0" in /boot/loader.com
kern.timecounter.hardware=HPET in /etc/sysctl

In the chromium browser, the sound is still skipping, although maybe not quite as bad.
VLC seems to play the audio and video just fine.
On my PC, playing video with my jellyfin server is just awful. Although my jellyfin client on my roku does just fine.

I don't know if this matters, but the audio on my motherboard is supposed to be: Realtek ALC892 audio codec.
But in /dev/sndstat, the audio is listed as:
Installed devices:
pcm0: <ATI RS690/780 (HDMI)> (play)
pcm1: <Realtek ALC887 (Rear Analog)> (play/rec)
pcm2: <Realtek ALC887 (Front Analog)> (play/rec) default
pcm3: <Realtek ALC887 (Onboard Digital)> (play)

what sound demon are you using, if any?

If you just use mplayer on OSS, does it also skip?

 

[walterbyrd]

I do not seem to have a sound daemon or mplayer.
$ ps aux | grep -E 'sndiod|pulse|pipewire'
$
$ mplayer
bash: mplayer: command not found

Is your Chromium hardware acceleration enable or disabled? Try toggling it to see if it helps with your audio.
