no stereo sound

I have been using beowulf/MATE for quite some time now, and have almost zero issues with it. But I do have one thing:

The sound output as shown in the 'Sound' app under 'Sound & Video' in the MATE menu shows as 'HD Intel PCH mono'. That is the only output device shown. In buster/MATE, it shows as 'Built-in analog stereo sound' (something close to that - going by memory here). This is also how it showed up in ascii/MATE.

This issue is present whether it's a clean install of beowulf or and upgrade from ascii, and whether I use pulseaudio or apulse. I would like to improve my sound quality, so if anyone has any ideas as to how I might fix this, I'm all ears :-)

TIA...

Re: no stereo sound

Hi

First try from commandline with alsamixer. If you get sound alsa is working (and this is just fine. Pulseaudio is just an unnecessary layer). Then install volumeicon-alsa. It is gtk based and can replace the pulseaudio based frontend on your system. Can be placed on the menuline as well.

Have a nice day

Re: no stereo sound

also in alsamixer, you may be able to set the default device. hth

I have sound - just not stereo. Alsamixer doesn't seem to offer any other options.

Re: no stereo sound

Hi

You can choose soundcard in alsamixer by pressing F6. To adjust volume make sure "Master" is selected (or headphone if you are using that) and then arrow up(down to adjust.

It looks like jack soundserver and pulseaudio is running. If jack is running (and as a musician I am using it myself when needed) please stop the daemon (maybe through qJackĆtl or commandline). Jack prevents other servers (as alsa) to use the soundcard. Just use jack for recording and mixing sound at a (semi) professional level. It does not work by default on games and in browsers. Pulseaudio also makes the setup more complicated than it need to be. Edit /home/user/.config/pulse/client.conf and set autospawn = no. Then it will not restart by iself when you stop it. Log out and in. If needed stop pulseausio by passing pulseaudio -k in a terminal. Using just alsa is the simplest way to get audio as an ordinary user on Devuan.

Hope this helps
Lars H

Hi,

Well, F6 does not show any other sound devices. The only thing jack related installed is libjack-jackd2, and I don't see any jack server process running. I got rid of pulseaudio altogether. Sound works, the mixers/volume controls/multiple audio apps all work - just not in stereo. In Debian buster, which is configured almost identically, it's stereo, and the output device is shown as Built-in Audio Analog Stereo. I just can't figure out what Devuan is doing differently...

Thanks for your input - somewhere in all this is a clue...

Re: no stereo sound

In the report of aplay -L at post #7, it says

pulse
    PulseAudio Sound Server

That's an indication that there is pulseaudio residue. One thing in that is that it declares the "default" output to be via "pulse" which makes the connection to its audio library. That is all separate from the running or not of the pulseaudio program. To be sure, you should remove the associated configuration files.

Then you might look at what amixer -D default tells about the available controls.
