FreeBSD 13.0 HDMI audio slow motion

Good morning, I have a stable FreeBSD 13.0 and I am very happy with my operating system that I met in October 2020 when my PC was very slow because the computer's battery was (dead) going into Powersave mode (at the time I didn't know it existed, my computer was very slow and I looked for a more efficient system. Some time later, I found out that I could change the processor governor and the computer become fast again, but I was fall in love with FreeBSD, that's uses Powerd). I looked for other operating system and saw one that was very interesting, FreeBSD, although people don't use it as the day-to-day operating system and youtube videos mostly just install on virtual machines. It is amazing to build your own operating system in every detail. Everyone who knows my operating system is delighted: it has an XFCE4 environment, it has XScreensaver, free games, a printer, folders and videos open faster than the blink of an eye, mount a USB stick, ext4 external disk and even the shared Iphone folders (I couldn't get the pictures folder).
But something bothers me a lot, which is that the audio doesn't work properly, in this case, only the HDMI audio, which works, but the audio is in slow motion, I've been trying to fix it for months. I know that there are several very cheap alternatives like buying a speaker via cable or even Bluetooth, or, even buying devices that combine HDMI and audio. I am unemployed, no matter how cheap I can't spend on anything. When I worked, I was a teacher (chemistry) and to transport a speaker for 40 people to listen quality audio is difficult because we already carry a lot of material.
As an alternative to unemployment I would like very much to format computers (R$ 100.00 = US$ 20.00 each), but I want to install only FreeBSD because of the impressive speed of this system that never crashes, but it is difficult to sell something that sin in any detail. Without Netflix you can still try to convince, but without perfect audio, I missed 6 opportunities because of this defect.
In short: The audio works well, except HDMI (/dev/dsp0) which works in slow motion. My sound card is Broadwell. The best driver I tested was pulse audio (songs in flac format are in slow motion with other drivers even for /dev/dsp3 (internal) or /dev/dsp4 (headphones)).

There is my cat /dev/sndstat:
Code:
Installed devices:
pcm0: <Intel Broadwell (HDMI/DP 8ch)> (play) default
pcm1: <Intel Broadwell (HDMI/DP 8ch)> (play)
pcm2: <Intel Broadwell (HDMI/DP 8ch)> (play)
pcm3: <Realtek ALC255 (Internal Analog)> (play/rec)
pcm4: <Realtek ALC255 (Front Analog Headphones)> (play)
No devices installed from userspace.
There is my /etc/rc.conf:
Code:
oss_enable="YES" 
pulseaudio_enable="YES"
sndiod_enable="YES"
sndiod_flags="-a on"
linux_enable="YES"
linux64_enable="YES"
jackd_enable="YES"
jackd_user="herbert"
jackd_rtprio="YES"
jackd_args="-r -d oss -r48000 -p1024 -n3 -w16 -o8 \
                  --capture /dev/dsp3 --playback /dev/dsp4"
And finally, there is my /etc/sysctl.conf:
Code:
debug.debugger_on_panic=0
hw.snd.default_unit=0
vfs.usermount=1
hw.snd.vpc_0db=45
hw.snd.vpc_mixer_bypass=1
hw.snd.latency=4
hw.snd.feeder_rate_quality=2
hw.snd.maxautovchans=2
hw.snd.vpc_autoreset=0
hw.syscons.bell=0
I would like to thank the FreeBSD community, which is small but very welcoming.
 
Hello herbertpfp,

nice to see that you are happy about FreeBSD.

To narrow down the problem more: Can you also confirm this problem if only the base sound system is in use? (No jack, pulseaudio etc.. and testing sound with apps that do use OSS like mpv, firefox etc..)

BTW: I dont know if you know it already but
Code:
oss_enable="YES"
is for audio/oss which is an different implementation. FreeBSD uses OSS in the base and the other thing is OSSv4.

From package description:
"Not to be confused with sound(4)() which is a different implementation with the same API."

From package description:
Yes, I've already tested this and all the possible combinations rebooting my Machine and sometimes causing strong songs and crashes. OSS_Enable causes a kernel warning, that the message is that I need to build a custon Kernel. I migrate from FreeBSD 13 alpha2 to the stable version via github, but I don 't know why I generate a custon kernel (without the sound), if you know where I can find this information, I not tested yet.
 
Compiling FreeBSD kernel is nothing compared to linux kernel configuration madness. Its pure joy. Also easiest configs can be made by just including GENERIC and undefining options.
 
Welcome herbertpfp
a pair of things,that may be help you
one, (first make a backup of the files that modified)

1) remove everything relating to
Code:
hw.snd
except
Code:
hw.snd.default_unit=0

2) leave rc.conf like this

Code:
oss_enable="YES"
linux_enable="YES"
linux64_enable="YES"

for now lets focus on OSS

3) the slow sound is like the "too fast" device rate configuration
add to your sysctl.conf

Code:
dev.pcm.0.play.vchanrate=44100

reboot and see what happen with for example audacious playing a song,etc

and remember , before modify anything make backups of the files

good luck!!!

I forgot, for compiling the kernel just place it in /usr/src
and run
Code:
make clean
make buildkernel KERNCONF=GENERIC
make installkernel KERNCONF=GENERIC
and reboot

Thank you a lot!!!! The user manual is too orientated to the developer, it's a week to me to understand. Preparing myself to do this operation for the first time without backup 1Tb of information.

maybe,but there is a lot of sources on google, dont worry, one thing take you to another and before notice your journey begin (sounds like a hobbit movie 😄 )
 
Since I'm going to get my hands to risk my system terribly, I thought of two scenarios:

1) Standard /compat/linux settings that everyone in the FreeBSD uses which is to call in /etc/fstab:

#Device Mountpont FStype Options Dump Pass
fdesc /dev/fd fdescfs rw 0 0
proc /proc procfs rw 0 0
linprocfs /compat/linux/proc linprocfs rw,late 0 0
linsysfs /compat/linux/sys linsysfs rw,late 0 0



2) Take a risk and bring a bit by bit copy of an Ubuntu 20.04 LTS totally updated and with all the programs compiled from the github repository, a show that everything works. However, it is known that all GUI interface programs (except synaptic) do not go up (systemd is not mounted). You can install any program via synaptic or apt-get or binary .deb (or use alien to convert RPM packages). Compiling on the basis of Cmake I was not able to native on FreeBSD (even less inside a virtual machine). Follows the required configuration in /etc/fstab:

#Device Mountpont FStype Options Dump Pass
fdesc /dev/fd fdescfs rw 0 0
proc /proc procfs rw 0 0
devfs /compat/linux_her/dev devfs rw,late 0 0
tmpfs /compat/linux_her/dev/shm tmpfs rw,late,size=1g,mode=1777 0 0
fdescfs /compat/linux_her/dev/fd fdescfs rw,late,linrdlnk 0 0
/tmp /compat/linux_her/tmp nullfs rw,late 0 0
/home /compat/linux_her/home nullfs rw,late 0 0

Which of the two options do you suggest me to try?
 
none of both, a good backup and fresh FreeBSD install, but is just me, I am closer to be purist in my system
I dont want to mix the Linux compatibility layer with Freebsd
but here there is a lot of users that make amazing thinks mixing the 2 worlds and make Linux application run on FreeBSD
 
PS: the second scenario gives me the opportunity to put the original module from intel video driver, because mine on FreeBSD complains about loss of power on boot, and it 's true: with Ubuntu my machine was able to have an HDMI conexion to transmit a virtual class, FreeBSD freezes only in this situation, and, in addition, the app on internet is heavier than the binary .deb app

We need a copy of wine with WOW64 too...

I agree with you, the important is my sound working fine. I use a copy of virtualbox everytime inside the startx to have 200Mb more memory than in startxfce4 and use a full upgraded win10 with about 2Gb of ram and the speed is good.
 
I run freeBSD raw - no emulation. I haven't had time to install sound. I use my remote to switch my Sony X80H from HDMI1 to built-in Google Smart Android TV to watch TV or do Google Play things. I wonder how many will be seeking "easy up and running multimedia" for freeBSD in the future, when pressing "HDMI2" solves all the media needs.

Audio HDMI compatibility is nothing minor. It's IEEE stuff - there are many HDMI out there and they are all "machines". The specifications are very deep.

Your trying to get HDMI working in a virtual box. I think that's "not fair to expect freeBSD to do". You are using a linux based virtual machine if I understand correctly. That's a linux question for QEMU, if that is the VM your using. QEMU has "drivers" which pass (or perhaps block) hardware information going from your linux emulated sound driver (which very likely doesn't support HDMI audio totally) and passes that to Microsoft windows QEMU, which again doesn't totally support HDMI to Windows to (perhaps your video card, which again may flub HDMI audio in some video formats or when talking to a broken request not completely IEEE compliant).

In short. I would try what these people are saying to do not ignore them. But your time is better spent getting something that does work

Now, intracting a "windows has audio ergo it has no probles", well, my Windows 10 continually updates and has root consoles opening when I'm working ... And I don't like Disney icons. Let's not start with whether a platform which has drivers is "the winner of end all".

I'm not inside a virtual box, quite the contrary, I'm making FreeBSD my system, which even runs windows inside a virtual box and that can even format a pen drive or start the webcam. Sorry if my English is not clear.

I prefer it with minimal emulation, like you, but windows binaries are always needed to work in almost any company. I am still taking courage to install this custom kernel, but I believe it is a conflict problem, and that disabling the conflict will transmit perfect audio. Here at home I turn on my computer to a 1990s sound with 4 speakers and four small horns, or the analog sound of my old TV with VGA input. But when I teach, the class cannot remotely drop, it loses recording, and live I need the television in the classroom to release audio, you can't load a device that generates sound for a room with 40 students, cause you carry books, dyaries, tests, HDMI cable.
 
Thank you very much wolffnx, Alexander88207, Debguy and tyson. I finally compiled a new kenel, but with no effect. When the sound module is uninstalled, no other module can be installed. Removing all modules is an option that compiles, however, no audio mixer is available, so there is no sound. Then OSS_enable continue genarating conflict. I didn't get HDMI audio working 100%.
 
I did read this thread once again. My main language isn't English, but looks like herbertpfp isn't too, but i think we will find common ground.
FreeBSD is not Linux. It don't need any 'outside' tools to have sound. So OSS from ports is not needed, and i think its so old implementation it wouldn't work good for you anyway.
Pulseaudio - its another layer of adding complexity/bugs which isn't really needed if your program support oss (FreeBSD integrated one of course).
Please explain your use case with apps you use to play audio, your hardware, etc.

PS. About installing kernel- did you use same src as your machine is running atm.? For example is it 13-BETA3 with this sources installed in /usr/src? Did u run make buildkernel KERNCONF=yourconfig when yourconfig is placed in /usr/src/sys/*ARCH*/conf/ than installing it with make installkernel KERNCONF=yourconfig?
PS2. Of course none of above shouldnt be needed, if you just use build-in OSS.
 
like tyson I see the post again and again..until I got it
you shoud have sound with a fresh install of FreeBSD , with OSS and without compile nothing

only change the default sound output to hdmi , to my setup only 2 steps:

1)identify the output number
Code:
# cat /dev/sndstat

Installed devices:
pcm0: <NVIDIA GTX550 (HDMI/DP 8ch)> (play)
pcm1: <NVIDIA GTX550 (HDMI/DP 8ch)> (play) default
pcm2: <NVIDIA GTX550 (HDMI/DP 8ch)> (play)
pcm3: <NVIDIA GTX550 (HDMI/DP 8ch)> (play)
pcm4: <Realtek ALC887 (Rear Analog)> (play/rec)
pcm5: <Realtek ALC887 (Front Analog)> (play/rec)
No devices installed from userspace.

2)make the number 2 in this case the default output

Code:
hw.snd.default_auto=0
hw.snd.default_unit=1
dev.pcm.1.play.vchanrate=44100 #for the "sound playing too fast"

reboot if you want

So Tyson, my use of HDMI audio would be to show recordings of chemistry experiments in the classroom, or even, in remote classes by the computer. Remote classes are also a problem, which unfortunately, because there are no binaries for the Zoom and Teams programs, they run very poorly by the browser. And to make the row call of the students I used a Microsoft Program emulated by wine (not possible at FreeBSD).

I entered the folder /usr/src/sys/amd64/conf and copy the generic Kernel using sudo cp -r GENERIC ALANA, and edited the file:
# Sound support
device sound # Generic sound driver (required)
#device snd_cmi # CMedia CMI8338/CMI8738
#device snd_csa # Crystal Semiconductor CS461x/428x
#device snd_emu10kx # Creative SoundBlaster Live! and Audigy
#device snd_es137x # Ensoniq AudioPCI ES137x
device snd_hda # Intel High Definition Audio
#device snd_ich # Intel, NVidia and other ICH AC'97 Audio
#device snd_via8233 # VIA VT8233x Audio

Then I ran the following commands in /usr/src:
make clean
make buildkernel KERNCONF=ALANA
make installkernel KERNCONF=ALANA

If I comment device sound, the kernel warning disappears, but I can't install device snd_hda and I have no mixer and no sound. I must install them.

I liked FreeBSD a lot, but when it comes to work it may be difficult for what I need. I need the computer not to crash while taking online classes, audio and video work well. Compatibility with an version of wine with WOW 64.

PS. My kernel version was updated to stable version 13.0 two weeks ago via github.

My audio is too slow, I tried vchanrate 44100, 48000, 96000 and 192000, no effect.

If I comment device sound, the kernel warning disappears, but I can't install device snd_hda and I have no mixer and no sound. I must install them.

Did you reboot after that ? Try commenting both sound and snd_hda entries, than rebuild, install, reboot with new kernel.
Next step would be install audio/oss to test, than enable oss service.
Try it with service oss onestart after you install that port.

I tried without sound and snd_hda, the problem is that without snd_hda I have no mixer and no sound (I use DSB mixer and TrueOs mixer to change the channel, but I can also edit on /etc/sysctl). I already have audio/oss installed (and some linux-c7 ports too) and oss_enable on /etc/rc.conf. I will do again the kernel, and reinstall audio/oss, but before, any other idea?
 
Sorry man. I had to move my TV(good its only 32'') to be sure this thing is working good. Works perfectly fine here.

I had to install graphics/drm-kmod to get it working tho, as my main display device is NVIDIA.
No need for fancy mixers, just did some multimedia/mpv test and it worked fine, my cpu is ivybridge i7-3770.
