I just setup freebsdFreeBSD on a macbook pro. I've got everything working mostly correct except now there is no audio at all. I installed firefox, chrome, vlc, xorg, nvidia drivers and a few other things. Here's a list of the installed programs.

sorry for all the text attachment but my mouse/ copy pasting isn't working very well in xterm at the moment.

I needed more space to upload additional files. I also attached my pciconf -lv

Any help on getting sound hopefully while avoiding pulseaudio.

As of FreeBSD 10, and above, snd_hda is statically compiled in the kernel. The snd_hda entry in your /boot/loader.conf unnecessarily loads it a second time. The handbook needs to be updated to reflect this fact.

I did a quick web search (FreeBSD MacBook Pro) and also searched this forum (MacBook Pro), there were both web and forum hits. I'd link them except the hardware depended on the model of MacBook Pro. If none of the search hits are helpful, it would help to post the model of your MacBook Pro .

Another aspect is that your sndstat shows 2 sound devices
Code:
 Installed devices:
pcm0: <NVIDIA (0x0042) (HDMI/DP 8ch)> (play) default
pcm1: <NVIDIA (0x0042) (HDMI/DP 8ch)> (play)
pcm2: <NVIDIA (0x0042) (HDMI/DP 8ch)> (play)
pcm3: <Cirrus Logic (0x4208) (Analog 4.0/2.0)> (play/rec)
pcm4: <Cirrus Logic (0x4208) (Analog Headphones)> (play)
pcm5: <Cirrus Logic (0x4208) (Digital)> (play)

Unless you specify otherwise, the default device is pcm0. Most laptops would wire the speakers to the Cirrus Logic sound chip. The Handbook, section 7.2.3 tells how to change the default sound device.

I removed the snd_had from my /boot/loader.conf but there is still two sets of audio devices being shown. If I remember correctly from debian I rarely used the HDMI ones, unless the mac was connected to a t.v.

There's the hdmi ports that control the internal sound chip and then the headphones but I am not sure how they are connected.

here's two more updated documents.

The macbook details are, not working atm... seems like dmidecode is just returning empty strings but I know it's worked before on linux. I will update this thread once I get that information.

If you plug the MacBook into a TV, the default sound setting may work.

If instead you want to use built in speakers try the steps below.

Using the handbook section I linked above I would run the following command as root
# sysctl hw.snd.default_unit=3

If sound then works, you can assign pcm3 as the default sound device with the following entry in
/etc/sysctl.conf
Code:
hw.snd.default_unit=3

I hope that this is enough information to get this audio issue sorted out on FreeBSD.

If you plug the MacBook into a TV, the default sound setting may work.

If instead you want to use built in speakers try the steps below.

Using the handbook section I linked above I would run the following command as root
# sysctl hw.snd.default_unit=3

If sound then works, you can assign pcm3 as the default sound device with the following entry in
/etc/sysctl.conf
Code:
hw.snd.default_unit=3

The audio has never worked on freeBSD it works on linux. Setting the device also doesn't work.

I've tried setting the new sound device, quitting firefox, relaunching firefox and trying to play a youtube video.

I've tried it on all snd hardware but so far none of them works.

Can you provide any other tips or link to those articles you were referring to earlier?

I found this article that talks about settings home boot hints: http://blog.hplogsdon.com/tuning-freebsd-for-apple-hardware/
I also saw a forum thread talking about the same things.

How do you find these device ids to use to set the hints? Are those documented somewhere?

Here's the relevant parts sans the adding snd_hda(4) to /boot/loader.conf

Sound and Audio
Both my iMac and my MacBook Pro use snd_hda(4) as the driver. I've now compiled it directly into the kernel, but it can be easily loaded with
kldload snd_hda

or by adding this line to /boot/loader.conf:
Code:
snd_hda_load="YES"
But, with both computers, sound still didn't work. Right now, a month or more after running BSD almost full time, at least on my MacBook Pro, it still isn't working completely correctly. On my MacBook Pro, the lines I stick into /boot/device.hints to get my sound working through the speakers is:
Code:
hint.hdac.0.cad0.nid10.config="as=2 seq=2"
hint.hdac.0.cad0.nid12.config="as=4 seq=1"
hint.hdac.0.config="gpio0"
and in order to route it through the headphone jack, I have to stick these lines into /boot/device.hints:
Code:
hint.hdac.0.cad0.nid10.config="as=2 seq=2"
hint.hdac.0.cad0.nid11.config="as=0 seq=2"
hint.hdac.0.cad0.nid12.config="as=4 seq=1"
hint.hdac.0.cad0.nid15.config="as=0 seq=2"
hint.hdac.0.config="gpio0 ovref"
As you can see, there is a bit of duplication. I'm not completely sure how to combine these two groups to get speakers to work by default. Whenever I have the headphone jack lines in the device.hints file, the speakers quite working. Whenever I remove them, the speakers work again.

And the fact that I have to reboot my fucking computer every time I make one change in order for the device to reconfigured makes the fine tuning of my speakers a bitch to do, so it might be a while until I figure it out.

On my iMac, the sound in tinny. There is no bass sound, and that sucks. Also if I bring both PCM and VOL volumes up very high, and REC is up even a tiny bit, the speakers go haywire and the girlfriend starts throwing shit at me to turn it off. I haven't given up on adjusting the sound, but it takes a lit of effort.

I'll continue to edit this post as more information comes up... I can't remember thing that I have done.

Actually, I think I found it with sysctl -a | grep hda, here's some output. Anything looks out of the ordinary? Any documentation on working with these things, this is totally uncharted waters for me.

Sound chips that use the intel hda specification have many, many pins. Most laptop manufacturers do not use all the pins, Different manufacturers assign the pins differently, ie Asus may assign pin 14 to the on-board speakers while Apple may assign pin 15 to the speakers.

In linux there is a large database (codecs) that specifies the pin assignments. There is variation within a codec and Linux users specify a particular variation in /etc/modprobe.d. FreeBSD does not utilize a database, it interrogates the pins during boot (nids in your hda.txt output) and groups them based on location of the jacks. FreeBSD sound configuration does not always configure the pin assignments correctly or as you would like them. FreeBSD users can re-assign the pins using the /boot/device.hints file. device.hints(5)

If you just want to get the laptop working, I believe the fastest way is to search for your particular laptop model and FreeBSD. Someone likely has already worked this out.

If, instead, you want to understand what you are doing, I would read snd_hda(4) and search this forum. There are at least 8 or 9 posts where non-working sound has been sorted out and fixed.

One key thing in the snd_hda man page is putting the speaker nid and headphone nid in the same association. If you then assign the headphone nid a sequence = 15, it should sense the headphone jack and mute any lower numbered nids, in that particular association, which are typically the onboard speakers.

The snd_hda entry in your /boot/loader.conf unnecessarily loads it a second time.
More specifically, it tries to load it a second time. There ought to be a way to silence the warnings if it is already loaded, like the kldload(8) -q option.

I recall some issues with sound in FreeBSD/Firefox. Playing an mp3 with simple player audio/mpg123 is a more reliable test. The handbook section I referenced above also tells you how to generate some white noise.

I don't have just a /dev/dsp, there's a /dev/dsp0.0% and /dev/dsp3.0% I am not sure what that's about to be honest.

I've also tried the sound on Firefox, Chromium, and VLC with an .wav file and nothing. The sound on the system is not functional. I saw this thread and asked over there as well : Thread 51788/

My understanding is that dsp0 corresponds to pcm0 while dsp3 corresponds to pcm3. /dev/dsp is suppose to be linked at boot to point to your default sound device. In your case, it is likely that pcm3 would be your default device. If you did not specify
/etc/sysctl.conf
Code:
hw.snd_default_unit=3
you will loose the link on reboot.
See this Thread 9413.

grahamperrin There are many other discussions on pulseaudio, alsa and oss. Even on linux I only used pulseaudio as a jack module because I rand a lot of music programs, mostly seq24, ardour, cadence tools which was tool to configure jack although I did it with scripts before. If FreeBSD cannot run audio, I would be pretty bummed because music is one of the main things that I do on the side.

shepper that still didn't work, not with firefox, chromium or vlc with local mp3. Earlier you said that linux had some database files that laid out how the pins were supposed to be arranged. Couldn't those be added to the FreeBSD project, even as a port or something? Also how could I find that database of sound card configuration data?

Right now I am not sure which path to take but I can't really use FreeBSD w/o sound as I do a lot of sound work second only to graphics programming.

Have a look at the snd_hda(4) man page, specifically the examples section at the end. You basically have to do a verbose boot, which will give you a lot of information, then adjust the pin layout accordingly.

This NID mapping is a highly Interesting topic...
If I understand this correctly this might be the reason why some sound cards with the same chip work and others not (i.e. no input and/or output).

Is it is possible to write a tool which enables one to check through all NIDS semiautomatically and quickly find those that actually "do the connection"?
Maybe such would allow to adapt generic chip drivers to all possible sound boards with varying NID mapping?

Maybe it could also be possible to use the ACPI information to get this information from the BIOS? Here a Linux-related article about this.

A generic verb pump sounds like a great idea.

Needing to turn mic bias on/off, to key a ham radio, I hardcoded the NID 11 of the mic in this particular PC.
Should have thought further. dev.hdaa.0.verb=0x123

Note the CTLFLAG_ANYBODY.

It is going to take more effort but as the MacBook Pro 11.3 is common, it would be worthwhile to work this out.

Start by posting the audio portion of your verbose dmesg as suggested by SirDice above.

My apologizes, I really didn't know there was a 20k limit on a forum post and once I started I didn't know what to do.

Does FreeBSD have it's own pastebin type service? Some communities are particular to that type of thing.
