Pulseaudio with Alsa using wrong sound card and non working 5.1stereo

I have a MSI WT72-6QL Workstation Xeon, Its proven to be a challenge getting everything working properly in Linux.  The sound issue has proven to difficult for me to fix without assistance.  Here is the info about my system.   

/etc/modprobe.d/alsa-base.conf

options snd-hda-intel index=2,0 bdl_pos_adj=1,64 snoop=0

$ aplay -L | grep :CARD

Card 2(HDA Intel PCH) in alsamixer:
has 5.1 stereo in alsmixer, although the LFE is listed and on, but doesn't use the subwoofer as intended, instead it just has VERY low volume to match that of the PCM speaker.  No base?!  The subwoofer is located on the bottom of the laptop and is a DYnaudio speaker.  I don't think it is properly mapped.  MSI is not Linux friendly...I had no idea untill after I purchased it. 
Here is an image of the Alsamixer for Card 2(HDA Intel PCH):
http://i725.photobucket.com/albums/ww26 … usqvca.png

The Default Card PulseAudio and only has a Master channel
Card 0(HDA NVidia) is just the 3 S/PDIF channels.  (I should mention I am using my Nvidia Quadro as my default graphics card (I tried Optimus and Primus and Bumblebee to get both Intel and Nvidia to work but MSI's BIOS is not my friend, so its Nvidia by default.)

# vim:set ft=alsaconf:

I don't have an asoundrc in my {$HOME}.

I have tried everything I could google to get this all working properly, to no avail. 
I can't seem to get the Intel Card that shows up as Card2 for some strange reason(even without any options in Modprobe.d) to become the default sound card.  I have been able to get Pulseaudio show an option for 5.1stereo in the sound options  and pauvcontrol menus but only the 2 main front left and right actually work( it lists them as the rear speakers in this configuration).  I can use some help here, everything I have googled seems to b out of date including the Asound.conf options listed in the Arch-Wiki.  I'd also be thrilled to get the subwoofer to work like a subwoofer to! ;-)

Help

Re: Pulseaudio with Alsa using wrong sound card and non working 5.1stereo

A lot of random stuff here:

  1. What are the other options apart from index on the snd-hda-intel module for? Are you sure you need them? The index line is objectively wrong it should be 

    options snd-hda-intel index=0,-2

    as it seems your analog card is loaded first.

  2. If you intend to use pulseaudio, that asound.conf is complete overkill, and likely to break things. Remove/back it up and install pulseaudio-alsa instead. Reboot.

  3. Start playing something and post: 

    sudo fuser -v /dev/snd/*
pacmd list-cards
pacmd list-sinks
pacmd list-sink-inputs

General notes on that last point if you want to try things before I've seen these outputs.:

  1. You should have a 2.1, 5.1 or similar profile within pulseaudio (the list-cards output), switch to that in the "Configuration" Tab of pavucontrol

  2. If the subwoofer still doesn't work as intended, edit /etc/pulse/daemon.conf identify the following lines and make them read 

    enable-lfe-remixing = yes
lfe-crossover-freq = 120 #Change that to however frequency value you feel sounds best

    Restart pulse between tries with systemctl --user restart pulseaudio

  3. If it still doesn't work, go into alsamixer for your PCH card, and up the channel map control from 2ch to something that would represent a surround setup, like 6ch for example

Re: Pulseaudio with Alsa using wrong sound card and non working 5.1stereo

Thany You for your assistance.
I changed the '/etc/modprobe.d/alsa-base.conf' to match your suggestion

options snd-hda-intel index=0,-2

I removed the asound.conf, and have pulseaudio-alsa re-installed. And rebooted.
I have started playing music via Rhythmbox, and here are the results your requested.

sudo fuser -v /dev/snd/*

I enabled-lfe-remixing =yes and lfe-crossover-freq = 120 in /etc/pulse/daemon.conf.

I have restarted pulse and reset my PCH card in Alsamixer for 6channel and unmuted and brought everything up.  Then I went back in and PulseAudio shows 'Master Front', Mater Rear', 'Master Center', and 'Master Woofer'.  I made sure everything was unmuted and moved everything up.  Still a no go with the sound properly working.
It lists Analog Surround 4.0(only Rear right & left have output), Analog Stereo(Front left & right have output), Analog Surround 5.1(Only Rear right & left have output).

Any Ideas as to why it shows the channels unmuted and up yet I can't get any sound?
Thanks again for your assistance.

Re: Pulseaudio with Alsa using wrong sound card and non working 5.1stereo

What I find strange is that pulse doesn't find a 5.1 profile. Does aplay -L still list the 5.1 profiles? Was that what bpos param was for? What's the output of 

amixer -c0

I had done a lot of digging on Google before posting here, and  the MSI laptops are not well documented for Linux.   And what is documented is all for their gameing laptops not the workstations.

I recall that the 'bpos' param was something I came accross in a post for and MSI gaming laptops sound card.  So I had added it to see if it would help any....I can't say that I did or didn't...I just don't know.

I also meant to let you know that I just checked 'PulseAudio Volume Control' and It no longer lists the 5.1 in the 'Built-in Audio" profile it only has "analog stereo-duplex, analog stereo-output, analog surround 4.0 output + analog stereo input, analog surround 4.0 output, digital stereo (IEC958) output + analog stereo input, digital stereo (IEC958) output, and lastly analog stereo input."  And of course the 4.0 surround still only outputs sound to Rear right + left speakers.  LOL!!! 
I just opened 'alsamixer' and the "PulseAudio" Card only has 1 Master Channel.  It didn't keep anything that was set up yestarday, even if it wasn't working.  I just droped the other channels and went back to a single Master.  I'm sure you can feel my frustration....ahhhhh!   I truly appreciate your assistance, this has been driving me mental.

Bye-the-way; I generally use the Gnome-Desktop because thats what I started using way-way-back ages ago, and I am comfortable with it, I do also use OpenBox-Desktop with Compton from time to time.  The only reason I was sticking to PulseAudio is because it is pretty-musch intergrated into Gnome at this point.  I am however not against scrapping PulseAudio and using Asla, maybe with Jack or something.   I'm just leaving the posability to change open incase Pulse is to uncooperative to get working with this MSI.  Should you feel that would be a better route to take I am agreable; but I would still require detailed assistance, as I have know Idea as to how to make that work.
Food for thought.

Re: Pulseaudio with Alsa using wrong sound card and non working 5.1stereo

That the pulseaudio mixer in alsamixer only shows a single master volume is completely normal and expected don't worry about that. The configuration on pulse side must be correct, the right thing on the alsamixer side should happen when we achieved that. I see in your amixer output that the channel control is still set to 2ch, and I feel that this is key to solving this. My amixer syntax is rusty but 

amixer -c0 set 'Channel Mode' '6ch'

, if it doesn't just use alsamixer to set that same control. Do things change now? Does pulseaudio get a new profile 

systemctl --user restart pulseaudio

to be sure, if it doesn't and simply for veryfing this, does 

speaker-test -Dsurround51 -c6

at least give you output on all of your channels?

Re: Pulseaudio with Alsa using wrong sound card and non working 5.1stereo

I keep setting alsamixer to 6 channels, but it resets to 2 channels after a reboot.  After it is reset to 6 channels the PulseAudio Card has Master Fromt, Master Rear, Master Center, and Master Woofer as it's channels, the only thing is only the Front right and left channels actually paly sound.

amixer -c0 set 'Channel Mode' '6ch'
Simple mixer control 'Channel Mode',0
  Capabilities: enum
  Items: '2ch' '4ch' '6ch'
  Item0: '6ch'

And now PulseAudio says I have 5.1 surround, but again only Front right and left have sound.

speaker-test -Dsurround51 -c6

speaker-test 1.1.4

Playback device is surround51
Stream parameters are 48000Hz, S16_LE, 6 channels
Using 16 octaves of pink noise
Playback open error: -16,Device or resource busy

I can't imagine what is causing this.

Re: Pulseaudio with Alsa using wrong sound card and non working 5.1stereo

Try to disable pulseaudio for the duration of the speaker-test call 

pasuspender speaker-test -Dsurround51 -c6

if you still get the resource busy error, figure out the culprit with 

sudo fuser -v /dev/snd/*

Re: Pulseaudio with Alsa using wrong sound card and non working 5.1stereo

pasuspender would not disable pulseaudio, it kept giving an error about the -D.
So I stoped pulseaudio via systemd and ran the test.

I found in alsamixer that Card0 had reverted back to 2 channel stereo.  It seems to change from 6 channel back to 2 channel after every reboot.
It didn't make any difference in the end tough.
I was still only able to get sound out of Front right and left speakers.

pasuspender speaker-test -Dsurround51 -c6
pasuspender: invalid option -- 'D'
sudo fuser -v /dev/snd/*
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  joshva     8940 F.... pulseaudio
/dev/snd/controlC1:  joshva     8940 F.... pulseaudio
/dev/snd/pcmC0D0c:   joshva     8940 F...m pulseaudio
/dev/snd/pcmC0D0p:   joshva     8940 F...m pulseaudio

So I stoped pulseaudio with systemd and tried it again. 

systemctl --user stop pulseaudio
Warning: Stopping pulseaudio.service, but it can still be activated by:
  pulseaudio.socket
 systemctl --user stop pulseaudio.socket

And ran both tests again with pulse stopped.

 speaker-test -Dsurround51 -c6

speaker-test 1.1.4

Playback device is surround51

Nothing is listed here.  Also no sound is in use at this moment.
