Realtek ALC892 seems to work, but no sound comes out. Please help

Chris_H · #1 June 8th, 2012, 00:32

Greetings all,

Code:

FreeBSD udns 8.3-STABLE FreeBSD 8.3-STABLE #2: Sun May 20 22:25:10 PDT 2012
root@udns:/usr/obj/usr/src/sys/AMD64  amd64

OK. Now that I've got that out of the way, here's my situation:

I've got an MSI mobo with an AMD 3 core CPU. The sound is onboard, and is a Realtek ALC892.

loader.conf:

Code:

sound_load="YES"
snd_hda_load="YES"

I've searched the forums, read the handbook, following all the hints therein. I have 4 stereo output(s) -- front, rear, center subwoofer, & side surround. I have headphones plugged into each of those output(s),

Code:

# ls /dev/ | grep dsp
dsp0.0
dsp0.1
dsp1.0
dsp2.0

but performing the following:

Code:

cat /dev/random > /dev/dsp0.0
cat /dev/random > /dev/dsp0.1
cat /dev/random > /dev/dsp1.0
cat /dev/random > /dev/dsp2.0

produces no sound!

/dev/sndstat:

Code:

FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA Realtek ALC892 PCM #0 Analog> (play/rec) default
pcm1: <HDA Realtek ALC892 PCM #1 Analog> (play/rec)
pcm2: <HDA Realtek ALC892 PCM #2 Digital> (play)

--Chris

P.S.: Here's all the relevant output.

I don't see obvious problem in provided logs. It should work. Just make sure that in all 3 of your mixers "pcm" and "vol" controls are not set to zero.

You may try to update your system as I've just merged to 8-STABLE many HDA changes. I have no specific hopes, but who knows?

Chris_H · #3 June 8th, 2012, 15:18

Greetings mav, and thank you for your reply. I have the mixer vols set @75%. In fact,
I issued the following in an xterm:

Code:

# mixer pcm 100 vol 100

which reported:

Code:

Setting the mixer pcm from 75:75 to 100:100.

So all I can figure, is that it isn't "wired" correctly.
I notice in the following:

That the "speaker" is "[DISABLED]". If the colors mentioned in the output coincide with those of the output jacks; the "Rear" output has been disabled. As many times as I've read the snd_hda(4) man page, I can't quite grasp how I might "re-wire" the "speaker" output to [ACTIVE], or [ENABLED]. If you, or anyone else can think of something, I'd be very grateful.

Thanks again.

Oh. I forgot to mention in response; I've been tracking 8_STABLE, which puts me @ 8.3. Last kernel build was 05-20, which is only 3 wks. old. Can't imagine that being too old. But who knows.

**mav@** · #4 June 8th, 2012, 16:58

Modern CODECs usually have excessive functionality that may be unused in a specific setup. The driver prints [DISABLED] for parts of the CODEC that are not configured or not used for the configuration.

Chris_H · #5 June 8th, 2012, 18:08

Hello mav, and thanks for the reply.

I'm not sure I completely follow. Does this mean that it won't be possible for me to use the "speaker" output with FreeBSD? I currently have 6 stereo ports available -- line-in, front, mic, rear, center surround, and side surround. I would figure that given there are jacks (1/8") that they'd be available. Doesn't snd_hd(4) permit me to "wire" my chosen in(out)put(s)?

Thanks again, for the reply, mav.

--Chris

This would sure be a lot simpler, if I could simply solder the in(out)put(s).

**wblock@** · #6 June 8th, 2012, 19:04

Try the second output:
# sysctl hw.snd.default_unit=1

Chris_H · #7 June 8th, 2012, 20:24

Greetings wblock, and thanks for the reply.

Your suggestion had no effect, nor did

Code:

sysctl hw.snd.default_unit=2

On a good note; halting the system, and powering it off, then starting the system up again, did make the output to the "front" port work. Now, if I can just get the rest of them to work.

But at least I can hear files on the system.

Thanks again for taking the time to respond -- and for cleaning up my mess yesterday.

These pins are disabled not because they are "speaker", but because they are configured as unconnected. "Speaker" there is probably left from the default CODEC configuration and most likely it means nothing.
