I had this setup working fine in Arch a few days ago. The system froze (ended up being dirty contacts on my PCI wireless card) and after some cleaning and a reboot, I have no sound. The wireless card now works fine; however, even after removing it I still have no sound.
Motherboard: Asus E351-M PRO
Soundcard: ACL887-VD
The card doesn't exist in the HD-Audio-models.txt list, but since it worked before I don't think it's the cause of the issue. The closest options are:
ALC882/883/885/888/889
======================
3stack-dig 3-jack with SPDIF I/O
3stack-6ch-intel Intel DG33* boards
auto auto-config reading BIOS (default)To load the card, I selected the following options in /etc/modprobe.d/alsa.conf:
options snd-hda-intel model=auto position_fix=3This is the same setup that a previous Arch user had success with (https://bbs.archlinux.org/viewtopic.php … 8#p1046038)
Looking at aplay, everything still looks to load fine:
$ aplay -l

defaults.pcm.card 1
defaults.pcm.device 0
defaults.ctl.card 1All the modules seem to be loaded correctly and alsamixer works fine and all the controls show up. When I mute/unmute the Master and Front channels I can even hear the small "thud" through the speakers as the channel gets activated.
The only thing that i'm not entirely convinced about is if the default "PCM" output is tied to the front speakers - and not some other channel. I have selected "2 channel" output in the appropriate spot in alsamixer but am unsure how this is handled by alsa. Can anyone confirm if the "speaker-test" command below will force output through the front speakers? The command executes happily (with no warnings or errors) - just NO sound.
speaker-test -Dhw:1,0 -c2Any other suggestions would be greatly appreciated! This whole issue is very annoying - especially since I have no error messages to work with - and is making my HTPC useless!!.

Instead of messing with .asoundrc, use module parameters: https://bbs.archlinux.org/viewtopic.php?id=134145

Thanks for your response. I'll give this a try when I get home.
The Intel HDA driver has the following options ( http://www.alsa-project.org/main/index. … -hda-intel ):
description: Intel HDA driver
author: author unknown
license: GPL
parm: index:Index value for Intel HD audio interface. (int)
parm: id:ID string for Intel HD audio interface. (charp)
parm: model:Use the given board model. (charp)
parm: single_cmd:Use single command to communicate with codecs (for debugging only). (bool)
parm: enable_msi:Enable Message Signaled Interrupt (MSI) (int)
parm: enable:boolI'm guessing that loading my sound module with the options below should just reorder my cards. If not specified, does Arch always take card 0 as the default output device?
options snd_hda_intel model=auto position_fix=3 id=SB index=0Do I then need to edit my asound.conf to represent something like what I have below or will alsa do this automatically?
pcm.!default {
type hw
card SB
}
ctl.!default {
type hw
card SB
}Do I need to include any other options to make sure that alsa is using "device 0" (my analog output)? How does this bridge my default PCM output to the front speakers?

Dooooon't use the .asoundrc from that thread! It disables dmix. Just find out the IDs and use the module parameters appropriately.

Gusar, still no change.
I removed my asound.conf and then reloaded my sound modules with the following options:

OK, some additional information. I installed the HDA-analyzer tool and browsed through all the available codecs and mixers. Aside from the large quantity of information available, two things sparked my interest:
1. There are a bunch of nodes that correspond to each audio output and none of them are muted (all have mute=0). All of these inputs and outputs seem to correspond to alsamixer channels.

0x04 0x0bMy front channel is node 0x02 and the corresponding audio mixer is 0x0c. The mixer is also connected to node 0x0b, which appears to handle the front/back line-in and mic channels.
Does anyone know if these mixers have an "auto" mute when there is no input?
Alamixer does not seem to have access to these hardware mixers. Is there a way to unmute them manually?

Still no solution, however to answer one of my own questions, I can use
hda-jack-retaskto override the internal driver settings.
HDA-jack-retask Description:
"Although primarily meant for power users, it focuses on simplicity: Just select your codec, then select which pins you want to override and what you want them to override to: Headphones, Line Out, Mic, Line In, and so on. There are buttons for trying it out right away, and for making your override the boot-time default. And of course, a button for removing all overrides in case things did not go as planned."
Another very cool tool is the HDA codec graphing tool. This tool's generated graph depicts the HDA codec layout and node connections (something I was trying to do using the HDA-analyzer text output).
codecgraphIt is available at http://helllabs.org/codecgraph/

Following the instruction from http://www.alsa-project.org/main/index. … -hda-intel
I installed the latest git module for snd-hda-intel (alsa-driver) and the newest alsa-lib.
Everything loads fine, but still NO sound from the speakers (speaker out or headphones).
Does anyone know how to exclude a hardware problem (aside from wiping arch and installing windows)?
