5.1 audio channels in PC- BSD

[carlosalvet]

Hi I am new in Free BSD so that I am using PC-BSD for comfort.

Before i was using Ubuntu and i decided for this SO thinking in more stable system.

I have a 5.1 audio channel speakers and i don't know how to configure them in my PC-BSD i could read about a virtual channel but i didn't understand very well. Someone can tell me how can i do to has my 5.1 audio channel output working very well?

thanks before hand!

in this page http://www.freebsd.org/cgi/man.cgi?q...eBSD+8-current i found a several steps

cat /etc/sndstat

FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA Realtek ALC885 PCM #0 Analog> (play/rec) default
pcm1: <HDA Realtek ALC885 PCM #1 Analog> (play/rec)
pcm2: <HDA Realtek ALC885 PCM #2 Digital> (play/rec)

my sound driver is: snd_hda_load="YES"

it says in

http://www.freebsd.org/cgi/man.cgi?q...eBSD+8-current

and I added this control in /etc/sysctl.conf with:

snd_hda_load="YES"

and then add the hints to start in the reboot

           hint.pcm.0.at="isa"
           hint.pcm.0.irq="5"
           hint.pcm.0.drq="1"
           hint.pcm.0.flags="0x0"

and with the hints the sound drivers crash so after reboot the devices are undetected and i can't continue

in the first link following the instructions found with this hints added.

#hint.hdac.0.cad0.nid20.config="as=1 seq=0"
#hint.hdac.0.cad0.nid24.config="as=1 seq=1 device=Line-out"
#hint.hdac.0.cad0.nid26.config="as=1 seq=2 device=Line-out"
#hint.hdac.0.cad0.nid21.config="as=2 seq=0"

what's the meaning of "nid #" or where can i read about these? why 20,24 and 26? which may i use?

here is the data sheet of my sound card realtek ALC889

http://www.realtek.com.tw/downloads/...Downloads=true

I am really looking for information to my problem.

with this hints the 3th device is lost it and the SO recognize 2 sound drivers divece #0 and #1 but it doesn't care because these don't play any sound, just follow the song with play and without any sound.

thanks before hand!

using this driver hda i can play 2.1 channel audio.

i read in datasheet and i can play the front principal channel 2.1, but the other 2 jack don't work.

i found this:

FRONT (Port D); Pin: 35.36; Location: Rear Panel; Front Channel Line Output and Amplified Output
SURR (Port A); Pin: 39,41; Location: Rear Panel; Surround Channel Line Output
CENTER/LFE(Port-G); Pin: 43,44; Location: Rear Panel; Center and Low Frecuency Channel Line Output
SIDE(Port-H); Pin: 45,46; Location: Rear Panel;Side Surround Chanel Output
MIC1(Port-B); Pin: 21,22; Location: Rear Panel; Analog Microphone Input
LINE1(Port-C); Pin: 21,24; Location: Rear Panel;Analog Line Output
LINE2(Port-E); Pin: 14,15; Location: Front Panel; Re-Tasking Jack Support Headphone Out (Default), Microphone Input and Line Input
MIC2(Port-F); Pin: 16,17; Location: Front Panel; Re-Tasking Jack Support Microphone Input (Default), Microphone Input and Line Input and Headphone Output

configuring my hints only could set up my front channel with

hint.hdac.0.cad0.nid35.config="as=1 seq=0 device = Line-out"

treat with

hint.hdac.0.cad0.nid35.config="as=1 seq=0 device = Line-out"
hint.hdac.0.cad0.nid14.config="as=1 seq=1 device = Line-out"
hint.hdac.0.cad0.nid39.config="as=1 seq=2 device = Line-out"

with no positive results just work 2.1 audio channels and no more.

You need to read the snd_hda man pages closer. It tells you what the nid# means.

More importantly, you shouldn't really need to mess with them. They are there to provide override to BIOS provided values.

You should get a verbose dmesg first to see what those are. Enable verbose as root by

echo 'boot_verbose="YES"' >> /boot/loader.conf

. After boot,

dmesg | grep hdac

and post it here. Also include the pcmX lines.

I've never setup 5.1 sound but maybe we can muddle through this.

*If you do not want to modify loader.conf then choose option number 5 to boot with verbose messages turned on. When the machine has booted, use the grep utility to find startup messages related to the sound system

[carlosalvet]

i did the

echo 'boot_verbose="YES"' >> /boot/loader.conf

like says in your last post and then search with dmesg and find this, I think that is good information for that
