only 1 sound output after upgrading to 8.1

P

Pluribootent

Hi, Im new to FreeBSD, installed 8.0 and upgraded yesterday using the freebsd-update method. I hope everything went successfully.
at least
Code: 
# uname -a
FreeBSD freebsd.box.org 8.1-RELEASE FreeBSD 8.1-RELEASE #0: Mon Jul 19 02:36:49 UTC 2010     root@mason.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64
looks fine.

After thh upgrade everything seems to work, but theres one thing:

I use 2 audio outputs from my onboard soundcard feeding 2 speaker sets. Before the update both were playing music out of the box. But now only 1 output is active
Code: 
$ mixer
Mixer vol      is currently set to 100:100
Mixer pcm      is currently set to 100:100
Mixer speaker  is currently set to 100:100
Mixer line     is currently set to  74:72
Mixer mic      is currently set to  75:75
Mixer mix      is currently set to   0:0
Mixer rec      is currently set to  75:75
Mixer igain    is currently set to  87:87
Recording source: mic

Im afmiliar with linux and there I can activate channels by alsamixer. I looked around and installed ermixer but the channel that is now dead doesnt seem to exist.

Maybe someone could suggest a solution? or a direction to look for or google?

My soundcard is ALC888
Code: 
snd_hda_load="YES"
from /boot/loader.conf

Thank you for your suggestions.
 
I'm also using ALC888, but experienced no analog sound output after upgrading to 8.1.

[CMD=""]cat /dev/sndstat[/CMD] showed default pcm() was set to digital (maybe the order changed).
So I've changed my previously set default output in /etc/sysctl.conf() back to analog pcm (hw.snd.default_unit=0 for pcm0).

With a 5.1 Surround Test File and dev.pcm.0.play.vchanformat=s16le:5.1 set in /etc/sysctl.conf my FL/CENTER/FR/RL/RR speakers are working (thanks to your post I've noticed it).

See sound()/snd_hda() for further documentation and adjusting settings to your needs.

With # [man]sysctl[/man] dev.hdac.0.pindump=1 you could dig further into your problem. See /var/log/messages for the pindump

What does your output look like (/dev/sndstat, sysctl dev.pcm, sysctl dev.hdac, pindump)?
 
thanks for your post and sorry for my late reply.

I had difficulty interpreting the output, because I havent a clue. Hope this helps someone to figure it ou.
Thanks!
 
Since 8.1 FreeBSD's snd_hda got real multichannel support. So stereo duplication is no longer used. To use it you should: make sound(4) use 4.0, 5.1 or 7.1 output, respecting your speakers configuration (see above message); and make your media player to playback multichannel content using all these channels (for mplayer see `-channels X` option). Note that mp3 is by definition is stereo-only, so unless you are using some post-processing in your player - it will be played to the front speaker's part only.
 
First one more output:

Thank you very much for your help!
 
/etc/sysctl.conf is empty

Ok, now I found smth:
Code: 
Aug 10 06:25:23 freebsd kernel: hdac0:  nid 21 0x01011412 as  1 seq  2      Line-out  Jack jack  1 loc  1 color   Black misc 4

This is the jack that I want to play sound. so its nid21? what would I do with it?
 
I spent hours on this now - no luck.
My aim: I want to have 2 jacks playing the same sound, I dont know how you call that, but I dont need 5.1, 7.1, Quadro or anything like that. Just simple same sound coming out of 2 jacks to feed 2 sets of speakers with the same sound. It works on windows, it works on my slackware distro and it used to work on my freebsd install, before upgrading to 8.1 ...

Code: 
# ls /dev/dsp*
/dev/dsp0.0	/dev/dsp1.0	/dev/dsp2.0	/dev/dsp2.1

What I did:
Code: 
cat /etc/sysctl.conf
# $FreeBSD: src/etc/sysctl.conf,v 1.8.34.1.4.1 2010/06/14 02:09:06 kensmith Exp $
#
#  This file is read when going to multi-user and its contents piped thru

#

# Uncomment this to prevent users from seeing information about processes that
# are being run under another UID.
#security.bsd.see_other_uids=0
dev.pcm.0.play.vchanformat=s16le:5.1
played around with 2.0, 4.0 and 7.1
only my Green jack gives me audio.
Code: 
# cat /boot/loader.conf 
autoboot_delay="1"
nvidia_load="YES"
snd_hda_load="YES"
vboxdrv_load="YES"
vboxnet_enable="YES"
hint.hdac.0.cad0.nid20.config="as=1 seq=0"
hint.hdac.0.cad0.nid21.config="as=1 seq=4"
hint.hdac.0.cad0.nid22.config="as=1 seq=2"
hint.hdac.0.cad0.nid23.config="as=1 seq=1"
hint.hdac.0.cad0.nid24.config="as=4 seq=0"
hint.hdac.0.cad0.nid25.config="as=5 seq=0"
hint.hdac.0.cad0.nid26.config="as=4 seq=15"
hint.hdac.0.cad0.nid27.config="as=2 seq=0"
hint.hdac.0.cad0.nid28.config="as=15 seq=0"
hint.hdac.0.cad0.nid30.config="as=3 seq=0"
hint.hdac.0.cad0.nid31.config="as=6 seq=0"
I also played around with the as and seq. Took me ages to find out the differences between "as" and "seq". Im still not sure about what Im doing.
I want the nid20 (Green) and the nid21 (Black) to play the same thing, so thats pcm0.
nid20 and nid21 have to be in the same as? And then I give them different seq? and set dev.pcm.0.play.vchanformat to s16le:2.0. didnt work. Tried it with 4.0 and set the nid20 to "as=1 seq=0" and the nid21 to "as=1 seq=4" and then to "as=1 seq=2", no luck.

It says in SND_HDA(4):
For output assotiations sequence numbers encode speaker pairs positions: 0 - Front, 1 - Center/LFE, 2 - Back, 3 - Front Wide Center, 4 - Side. Standard combinations are: (0) - Stereo; (0, 2), (0, 4) - Quadro; (0, 1, 2), (0, 1, 4) - 5.1; (0, 1, 2, 4) - 7.1.

Is Quadro what I want? but how do I set up (0,2) and (0,4). thats four numbers. Is quadro for 8 Speakers? I dont think, Quadro is what I want.

Im too stupid to handle this myself, but Im sure plenty of users have 2 sets of speakers connected to their machine.

Im sorry, if this all sounds dumb, I am dumb. Thanks for answers to this.

edit: I forgot smth:
I also did this:

I may have a similar problem. W/ 8.0, the 'fix' used to be that in /etc/sysctl.conf

Code: 
hw.snd.default_unit=1

would fix it but I found out I could no longer do it in 8.1.

My 'fix' was to just load snd_hda late in /etc/rc.local, and just hw.snd.default_unit=0 (default).

I am using a 780G mobo. I am not using 5.1 sound tho, just 2.1 so I can't go into the details as for the different channels.
