no sound play local music in vlc ,but could work in firefox online video

R

realneet

the problem confuse me and tried any way but usefulless
Code: 
cat /dev/sndstat
Installed devices:
pcm0: <Intel Broadwell (HDMI/DP 8ch)> (play)
pcm1: <Conexant CX20751/2 (Analog)> (play/rec) default
pcm2: <Conexant CX20751/2 (Left Analog)> (play/rec)
Installed devices from userspace:
dsp: <Virtual OSS> (play/rec)
 
I enabled sound with this:
sysrc sound_load=yes
sysrc snd_hda_load=yes

Make sure your system sound volume is at the highest level:
mixer vol 100

Forgot to mention that Firefox uses the playback device selected by pulse audio; I have KDE desktop with pulse audio mixer. I have seen similar behavior when the output device selected in pulse audio mixer is different from system's default playback device - VLC uses system's settings and Firefox uses pulse audio settings.

More on setting up the sound device at https://docs.freebsd.org/en/books/handbook/multimedia/#sound-setup.

thanks i will try !
today i use pkg install cmus to test a.mp3 then echo "ERROR selecting output plugin '': no such plugin "
BUT then i use ports to get source code of cmus,make package add the pulse support , it work very well without any mode change !
so strange😅

😅So complex
alway lack of any useful tool to solve similar problems

I wouldn't call these problems. These software are designed to work with different options/configurations. They come with some defaults, which can be changed as needed.

Firefox on my machine was installed from packages (with pkg), which has been compiled to work with pulseaudio, sndio, etc. It probably uses pulseaudio because it is available on my machine. VLC on the other hand, again installed from packages, has been compiled with pulseaudio off. I am sure both these software can be compiled with my choice of options if I use ports.

Probably due to different options used at compile time, as I mentioned above.

BTW, I think it is not recommended to mix packages and ports, if I am not mistaken.
 
You are enabling virtual_oss (or something is starting it), what configuration did you give it ? Since your default output device seems to be dsp1 I wonder which argument you give to the rc settings: virtual_oss_dsp.
What is the output of sysrc virtual_oss_dsp

In hindsight, I should have mentioned that this is the behavior on my machine. I have Firefox and VLC binary packages installed with pkg, pulse audio installed as part of KDE desktop and I do not have virtual_oss installed.
 
The Plasma pulse audio mixer, installed as part of KDE desktop, works partially for me - it controls the volume of system speaker/headphones and switches audio device, which works for Firefox. However, the volume sliders do not change volume for HDMI output or the mic. For that, I switch device with sysctl and use mixer. As I can very easily run these commands with Krunner, I did not try other mixers like audio/dsbmixer yet. There may be a better/easier approach than mine.

Yestoday i deinstalled oss and viturl_oss then delete related sets in rc.conf, it works well except my externel speaker, but i can live with that
 
I tried to install this desktop environment, but VLC is the only one that works
KDE is beautiful but resource intensive, so i had to switch back
Freebsd is a great system, but desktop applications still take a lot of effort on the part of users（me）


:-/
 
realneet, do you have pulse audio running now? If you have installed these audio/video players as binary packages, you may use pkg info to find out what output options they were compiled with.

should i use the pipewire to replace this? I heard it is a new platform
So many functions be off

:eek:
 
realneet, I think the above info is for pulseaudio. I meant that you can check the package info for the players (vlc, mplayer, audacious, etc.) to see why some are working for you and some are not.

Do you currently use a graphical mixer to control audio?

Could you please share the output from the following commands?
cat /dev/sndstat
sysctl hw.snd.default_unit
mixer
dmesg | grep hda*

I think pipewire is developed for Linux to handle video similar to what pulse audio does for audio in Linux. I see that a port is available for pipewire, but I have no experience with it to comment on it.
 
there's not many grafical mixer of mate desktop i use alsamixer in teminal

audio/mate-media provides mate-volume-control. There are other graphical mixers available too, like audio/dsbmixer; you can find them with pkg search or on FreshPorts.

I think mixer is more appropriate for FreeBSD.

From your previous outputs, it seems your sound devices are detected, but you may also have pulse audio running, which some applications like Firefox may be using as default. You may use pactl commands to investigate this further.
