pulseaudio wrong channels

dalu · 2018-05-22 13:41:36

I have a MSI GT72 2QE Dominator Pro laptop.

Realtek ALC892
using snd_hda_intel

With alsamixer I've configured it to be 6 channel output.
I've connected 3 analog cables, colored black, lime(green), light orange(not mic color) to a
Logitech z906 sound system. It's 5.1 system. DTS all that crap.

Now, I'm dual booting and the correct order of connecting the cables under Windows is black, lime, orange.
And it sounds very nice under Windows.

However i also use arch to work under Linux.
And with it, pulseaudio.

Now I've tried a number of things,
manually loading modules results in a timeout

$ pactl info
Server String: unix:/run/user/1000/pulse/native
Library Protocol Version: 32
Server Protocol Version: 32
Is Local: yes
Client Index: 16
Tile Size: 65472
User Name: darko
Host Name: wrk
Server Name: pulseaudio
Server Version: 11.1
Default Sample Specification: s16le 6ch 48000Hz
Default Channel Map: front-left,front-left-of-center,front-center,front-right,front-right-of-center,rear-center
Default Sink: alsa_output.pci-0000_00_1b.0.analog-surround-51
Default Source: alsa_output.pci-0000_00_1b.0.analog-surround-51.monitor
Cookie: 6f4c:2b57

The problem is, it sounds awful. Everything it seem it output on the physical front right speaker, it being the loudest and the rest is not as loud.

Front-Right is Rear-Right, Front-Left is Rear-Left
And physical rear-left is really low on loudness.

As you can see from the pactl info output, the "Default Channel Map" is off.
However:
in /etc/pulse/daemon.conf

default-sample-rate = 48000
default-sample-channels = 6
default-channel-map = front-left,front-right,rear-left,rear-right,front-center,lfe

But it just doesn't want to apply.
I don't know, why is there a global conf when it's ignored?
And why is it ignored?

fwiw

$ aplay -l

How do you change default channel map or channel map in general at runtime?

load-module module-remap-sink sink_name=remap51 master=alsa_output.pci-0000_00_1b.0.analog-surround-51 channels=6 channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe master_channel_map=front-left,front-left-of-center,front-center,front-right,front-right-of-center,rear-center remix=no

all it did was turn off channels

I've seen this:
https://wiki.archlinux.org/index.php/Ad … g_speakers

How do I apply that to pulse?
It should go through pcm remapping, then pulse

V1del · 2018-05-23 09:31:43

You really shouldn't try to bridge this over ALSA and then back to pulse, that will only lead to issues.

Your pulse remap should be correct (if you are sure of the identifiers for the maps) except for why did you add remix=no ? You want remixing to happen, otherwise stereo sources will only play front-left,front-right
Edit: Oh I see the docs mention that, but in your usecase you definitely want remixing to happen, strange that that page is written like the author is unsure of it's purpose

As for global conf ignorance, that would be relevant for selfadded sinks. Udev-detected sinks represent the capabilities and channel-maps as reported by the driver.

FWIW you also might want to refer to this thread OP sadly didn't post back, but it contains some discussion and a link that explains why channel maps don't necessarily map the same way on Windows and Linux.

and FWIW2 can you post, during such a situation where you feel you don't get the audio as you want it to

also
https://iuploa.de/v/x4z9BYkpNk1t
alsamixer

And the connection is from a 2014 thread on MSI forums, the only way to connect that worked

- Front cable (green): to Line out.
- Rear cable (black): to Line in.
- Center/Subwoofer cable (orange): to Mic in.

So if you're saying that the driver says that this is the way it needs to be, then I should get the driver provided by realtek.
However they're being elusive lately when it comes to drivers.

Hmm I'll try with remixing enabled, let's see what happens

update: realtek driver is the same as the one from alsaproject, so it says in the pdf and readme. And from realtek's page it's for 3.x kernel only anyway.

And by the way, the same (meaning, no sound sink available), when I manually load module-alsa-sink with the correct parameters.
It's as if the driver was sabotaged on purpose.

No I don't think this is necessarily the drivers fault, simply as mentioned in the link in the second post by brebs another interpretation of how the channel map should look like, this isn't set in stone and can be changed.

Another alternative to that whole dance with the remaps on the pulseaudio level, which might be more successful, is remapping the connectors to the layout you expect it to be using hdajackretask from the alsa-tools package.

Regarding the pacmd outputs. You should repost them during playback of audio, there are a few potential configuration quirks/tweaks which can only really be assesed when looking at how pulse tries to map the audio it receives.

Edit: Oh wow, that reads interesting

rebooting fixed the taint

yeah well regarding the differences linux/windows, I'm not going to plug it in differently every time I boot a different system, that's crazy talk
anyhow, now I have this appened at the bottom and I'm manually selecting that sink

load-module module-remap-sink sink_name=remap51 master=alsa_output.pci-0000_00_1b.0.analog-surround-51 channels=6 channel_map=rear-left,front-left,front-center,rear-right,front-right,lfe master_channel_map=front-left,front-left-of-center,front-center,front-right,front-right-of-center,rear-center remix=yes

the problem now is.
front-left is too silent
subwoofer is too silent

and essentially it sounds even worse than before, output is even more to the right than before with less bass.

Seems like I'll have to buy a copper spdif to optical spdif cable after all, how that's supposed to work, don't ask me.
And if I'll wager a guess new problems will arise with that.

V1del · 2018-05-23 11:19:21

If that channel map works now, can you still post the pacmd outputs during playback? In general if you want bass, you should enable lfe remixing in the daemon.conf and denote a frequency cutoff for when you want the bass to kick in. or use the special value 0 which will simply mix anything into the LFE channel to get you something.

Oh and could you replace that alsamixer image with a thumbnail/a direct link, full size images can be distracting/unexpected data usage.

Many channels on your remap sink are at 60% and your chrome isn't set to play back from it, are you sure that's what you want?

dalu · 2018-05-24 10:39:14

I'm not using remapped output but default and where do you see 60%?

Well if that works for you that's fine by me but I thought the intention was to verify if this works, and as you mentioned low volume these might be some knobs to change.

Edit: Regarding the volumes
