[SOLVED] Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

It has been a while since i had any audio-related problems with linux.
About 12 years ago, i upgraded Debian 4 to 5 or 6 and sometimes i couldn't get any sound out. I fixed that by saying "chmod o+rw /dev/dsp" as root.

Now it seems that there is no such thing as /dev/dsp anymore.

And the problem is, with this Fujitsu Lifebook U728 machine+Devuan Chimaera as OS,i can't get any sound out of it.
Audio mixer->Output Devices->show hardware outpur devices doesn't show any device at all.
Once played around with alsamixer. Didn't do anything at all.

Found this: https://bbs.archlinux.org/viewtopic.php?id=265211 , tried that "options snd-intel-dspcfg dsp_driver=1"-thing. Still hearing only the sound of silence.

Any ideas what to try next?

"lspci | grep -i audio" says:

00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

"lspci | grep -i sunrise" says also:

00:15.0 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #0 (rev 21)
00:15.1 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #1 (rev 21)

those lines may have something to do with that "dsp_driver=1"-thing.

So, any ideas how to make xfce's audio mixer find that sunrise audio device?

Quick solution would be to buy an usb soud card. I know one card that Just Works or at least it used to.
But it would be better to make the internal sound chip work.

maybe the second line is a good starting point, maybe not.

A similar issue was discussed two weeks ago. Maybe you can read it?

Hi, I use the same tech to keep hdmi out of my way.

.asoundrc overrides the automagic. No sound for other users incl root unless I add the rc file to their accounts.

Guess i'll look into that asound-thing some day. I may get bored booting with "super grub disk"-method, and kill 2 birds with 1 stone.
Not yet fully convinced that this sound problem is about configuration, but i'll find out soon enough.

Tried to boot Fujitsu with devuan live. It worked. And after that, tried youtube. I got sounds out of my hardware. So the silence may be a problem with configuration after all.

Now it seems that there is no such thing as /dev/dsp anymore.

PulseAudio can still emulate it, but virtually nothing uses it anymore. (I think NAS does, but NAS is itself a relic.) Pretty much every piece of Linux software written this millennium uses ALSA, either directly, or through an intermediary such as Pipewire or Jack.

Now it seems that there is no such thing as /dev/dsp anymore.

In any case, the command 

cat /usr/share/sounds/alsa/Front_Center.wav>/dev/dsp

does not work in Daedalus. Maybe it's just me?

Re: [SOLVED] Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

Either there were no /dev/dsp in my Chimaera install or "chmod o+rw /dev/dsp" as root didn't help. Not quite sure anymore which one was the case. Should document better.

Yep, still no /dev/dsp in Daedalus.
But installing wireplumber seemed to be the easy way out of silence.

Re: [SOLVED] Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

The device node /dev/dsp which belonged to the OSS (Open Sound System) was dropped from linux kernel more than 14 years ago. Since then sound has been ALSA (Advanced Linux Sound Architecture).

edit: I guess you could roll your own /dev/dsp with:

daemon -r socat pipe:/dev/dsp,umask=000 exec:aplay

Re: [SOLVED] Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

There's something missing in my Devuan.

root@devuan:/# daemon -r socat pipe:/dev/dsp,umask=000 exec:aplay
bash: daemon: command not found

P.S. This is purely for fun, probably not worth attention

Re: [SOLVED] Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

There's no .asoundrc  or asound.conf nor alsamixergui in my system. I'll have to install some packages. But anyways, wireplumber was the quick fix.

Yes, wireplumber acts as the (multimedia) server for pipewire that pulse did before.
