Realtek ALC255: no audio/sound with FreeBSD 14.2-RELEASE

someone231 · Sunday at 1:59 AM

Greetings,

I have installed FreeBSD and everything is working fine except audio.

here is the output of `dmesg | grep pcm` https://termbin.com/jtct

output of `dmesg | grep hdaa | grep Realtek` https://termbin.com/5rif

I don't know what am I missing, the audio isn't muted and I can see it in `mixer`

$ cat /dev/sndstat ?

here is the output I got: https://termbin.com/w6vx

I don't know what am I missing since the kernel detects the sound card but it doesn't play any audio/music and even the `beep` command doesn't make a sound. it's a weird issue.

Please show us the output of sysctl dev.hdac.0.pindump=1 from dmesg or /var/log/messages.

Paste the data in your next post for future reference (preferable paste the other termbin data as well). https://termbin.com/ stores the data sent only one week, then it's gone (see use policy # 7)

This command doesn't give the output you have provided instead it gives this:
`doas sysctl dev.hdac.0.pindump=1`
dev.hdac.0.pindump: 0 -> 0

When the command is executed in an Xterminal (or virtual console ttyv1 – ttyv7: Alt + F2 – F8), the output is not displayed there, you have to look at a dmesg(8) output, or /var/log/messages end of file.

The system console ttyv0 (Alt + F1) will display the pindump as well, but it's less convenient to copy from there into a forums post.

ohk, I was wondering why it wasn't working.

here is the output:

@T-Daemon what could be wrong here, I don't know how to interprete this output.

T-Daemon · 2025-01-22T13:08:59+0000

Which devices are connected to which line-out connection exactly?

There is a (Rear Analog Line-out)> at nid 27 [1] and a "connected" indicating Digital-out [2].

I had two things connected at the time I copied the output. one was in-built sound card and second was a jack connected to external speaker. however when I ran beep command I couldn't hear anything from any of them.
